DESCRIPTION
1.1 ADC FasTerm Singlemode FC Connector The ADC FasTerm Singlemode FC connector is a field-installable FC-type fiber optic connector for singlemode fiber optic cable. The term “singlemode” refers to optical fiber in which the core diameter is approximately 9 microns. Basic features of the ADC FasTerm FC connector include the following: • Fits either 3 mm or 900 micron fiber optic cable. • Can be installed using standard fiber optic tools. • Requires no electricity or curing oven for assembly. • Is fully compatible with all singlemode FC adapters that meet the JIS-C-5970 specification. • Includes a pre-radiused zirconia (ceramic) ferrule for exceptional insertion loss and reflectance performance. Each packaged ADC FasTerm Singlemode FC connector includes all the components shown in Figure 1; i.e., a connector body (with a protective dust cap on the ceramic ferrule at the front of the connector), a strain relief boot for use with 900 micron cable, and a separate strain relief boot (and crimp tube) for use with 3 mm cable. 900 µm STRAIN RELIEF BOOT

1.6 Safety Precautions Various safety precautions should be observed when installing the ADC FasTerm Singlemode FC connector. Specific warnings are included in the procedures where appropriate. This section provides a list of general cautions and warnings that apply when working in a fiber optics environment. Read and understand all cautions and warnings before proceeding. Warning: Invisible infrared radiation can seriously damage the retina of your eye. Do not look into the optical bulkhead of an operational transmitter; or into the launching (output) end of an active fiber. A clean, protective cap or hood MUST be immediately placed over any radiating bulkhead receptacle or optical connector to avoid exposure to potentially dangerous amounts of radiation. This practice also helps to prevent contamination of connectors and adapters. Caution: Improper handling can damage fiber optic cables. Do not bend fiber optic cable more sharply than the minimum recommended bend radius specified by the cable manufacturer. Do not apply more pulling force to the cable than specified. Do not compress the cable or allow it to kink. Caution: Glass fibers are very sharp and can easily pierce the skin or eyes. Do not let cut pieces of fiber stick to your clothing or drop in the work area where they can cause injury later. Safely dispose of cleaved or broken pieces of glass fibers. Wear safety glasses with side shields to protect your eyes.

CABLE PREPARATION AND CONNECTOR INSTALLATION Note: Assembly consists of preparing the fiber optic cable, potting the fiber, cleaving the fiber, polishing the connector, completing final connector assembly, and inspecting the connector. Throughout this section, the tools and materials in the FC Tool Kit are referred to by the item letter (A, B, etc.) listed in Table 2 (page 5) and shown in Figure 2 (page 4). Read through all assembly instructions before assembling connectors. Follow instructions completely and in the order in which they are presented. Caution: Wear safety glasses (Item R) before starting any of the following procedures. Small pieces of glass fibers are very sharp and can become embedded in the eyes. Small drops of adhesive and accelerator can be splashed into the eyes. Avoid the risk of eye injury by wearing safety glasses.
Note: If you experience any difficulty in either preparing the fiber optic cable or installing the connector, consult the troubleshooting section for recommendations.

4. Trim the Yellow Yarn a. Pull all the exposed yellow yarn to one side and gather it into a single thread for easier cutting. Note: The yellow yarn is extremely tough; however, it cuts easily after it is twisted into a single thread. b. Using scissors (D), trim the yellow yarn approximately 1/4 inch from the end of the cable jacket (see Figure 6). Then, fan out the yarn until it is again evenly distributed around the buffer. 3 mm CABLE

Note: If you are inexperienced in stripping fiber buffer, practice several times on some scrap cable to develop the proper stripping technique. If fiber breaks during stripping procedure, check closely for debris in the plastic head. Any such debris will prevent proper operation of the buffer stripper. 5. Detailed instructions for buffer stripper use: a. Hold tool with arrow on top (as shown in Figure 7). b. Insert fiber between plastic alignment teeth. c. Squeeze handle.

6. Strip the Buffer a. Using marker (A), mark the fiber buffer 5/8 inch from the end of the cable jacket. Figure 8 can be used as a template for marking the buffer of the 3 mm cable. b. Grip the cable firmly near the end, wrap the cable once tightly around two fingers of your left hand. Note: Holding the cable as described will help keep the fiber buffer from pulling out of the cable jacket while you are stripping the buffer. c. Using buffer stripper (F), strip off the fiber buffer in several small segments of approximately 1/4 inch each until the buffer is removed up to the mark. Note: Removing segments larger than 1/4 inch could cause the fiber to break. d. Check strip length. Figure 8 can be used as a template. Note: if the fiber buffer pulls out of the jacket during stripping, the strip length will be inaccurate. The buffer can often be slid back into the jacket to compensate. However, this can be avoided by gripping the jacket more firmly; otherwise, you should repeat the process from step a. YELLOW YARN BUFFER

2.3 Potting the Optical Fiber Potting, the process of securing the optical fiber to the ceramic ferrule with adhesive, is identical regardless of which cable size you have. To pot the fiber to the ferrule you will need the following items from the Tool Kit (in the order listed): • An alcohol wipe (S) • Adhesive dispenser (bottle) (C) • Dispensing tip (N) • Accelerator (spray can) (B) • Crimp tool and 0.151 inch hex crimp die (L) [3 mm cable only] 1. Clean the Fiber Using a supplied alcohol wipe (S), clean the stripped fiber by wiping once or twice along the length of the fiber.
Note: Make sure the cleaned fiber does not come in contact with anything until it is inserted into the connector. Finger oils or other contaminants (including wipes containing less than 99% isopropyl alcohol) may cause the adhesive to set while the fiber is being inserted into the connector.
Note: Each alcohol wipe may be used several times before being discarded. If the alcohol wipe becomes contaminated or is no longer damp, use a new wipe. 2. Insert Adhesive

ADCP-90-222 • Issue 2 • November 1999
Warning: The adhesive contains cyanoacrylate ester (i.e., “Super Glue”). Apply only to surfaces to be bonded. Do not get adhesive on your skin, in your eyes, or take internally. In case of skin contact, flush with water. Seek medical attention for any eye or internal contact. To avoid skin contact, use dispenser and dispensing tip provided. KEEP AWAY FROM CHILDREN. Table 3.

+10°C to 45°C (50°F to 113°F)
Operating
–40°C to 50°C (–40°F to 122°F)
Note: Shake the adhesive bottle well. a. Remove cap from adhesive dispenser (C), then install a dispensing tip (N) on the adhesive dispenser. Note: If you plan to install a series of several connectors, you may leave the dispensing tip on the adhesive dispenser. However, when using the same tip on several connectors, clean the adhesive off the outside of the tip with a tissue wipe before inserting it into the next connector. Failure to do so could cause the connector ferrule to seize, locking the connector. Discard the dispensing tip when all connectors are installed. b. Remove, but do not discard, the protective dust cap from the ferrule shown in Figure 12. Note: For best results, insert the clean fiber into the connector immediately after inserting the adhesive. If the adhesive has been in the connector longer than one minute, discard the connector and use a new one. c. Insert the dispensing tip (see Figure 12) into the rear housing of the connector, then push firmly (this makes a tight seal between the tip and the inside of the connector). If the dispensing tip is properly seated, the connector will stay attached to the tip when the adhesive dispenser is tilted downward. Note: It is important to fully insert and properly seat the tip into the connector; otherwise, the adhesive may overflow and ruin the connector. d. Tilt the adhesive dispenser downward, then squeeze the dispenser and inject the adhesive into the connector until adhesive is visible on the end face of the ferrule. Note: After the adhesive appears on the end face, STOP injecting adhesive into the connector or the connector ferrule will adhere to the housing and not move freely as it should. e. Pull the adhesive dispenser straight back until the dispensing tip is free of the connector. f. When you are finished installing connectors, remove the dispensing tip from the adhesive dispenser. Clean the end of the adhesive dispenser with a tissue wipe to reduce adhesive buildup, then cap the dispenser.

Note: Do not allow the connector to sit for longer than one minute after the adhesive is injected into it; otherwise, the adhesive may harden and prevent insertion of the fiber. If this happens, discard the connector and use another one. 3. Insert the Fiber Into the Connector a.
While holding the connector in one hand, insert the fiber gently into the rear housing of the connector until the cable comes to a stop and is snug inside the connector as shown in the 3 mm example in Figure 13. The fiber should protrude approximately one-half inch out the front of the ferrule at this time. Note: If the fiber is difficult to insert, or stops before it is completely inserted, rotate the connector back and forth while applying light pressure to the fiber. Note: When installing the connector, use care to ensure that the fiber does not move in or out after it is inserted and before the accelerator is applied.

4. Apply Accelerator a. While making sure that the cable is snug within the connector, spray accelerator (B) on the adhesive at the endface of the ceramic ferrule. Hold the spray can approximately 6" from the endface of the ferrule, and apply the spray directly on the endface. Avoid applying the accelerator from the side, which might blow the adhesive off the endface. Note: The accelerator causes the adhesive to harden in seconds. Without the accelerator, the adhesive will require a minute or longer to harden. The adhesive will not be harmed by application of too much accelerator; however, two squirts should be sufficient.
5. Crimp the Cable [3 mm cable only] a. After making sure the yellow yarn is evenly distributed around the outside of the rear housing, slide the crimp tube along the cable until it seats over the knurled section of the rear housing and captures the yellow yarn between itself and the rear housing. Then, using the smaller of the two hex slots on the crimping tool (L), crimp the entire length of the crimp, including the ridge at the rear (as shown in Figure 14), until the entire crimp is constrained to the hexagonal shape of the die. Allow the crimp tool to complete a full cycle (i.e., to click through its entire cycle and release). Note: Before crimping, ensure that the cable is butted firmly against the rear housing of the connector. CENTER CRIMPING TOOL IN THIS AREA

2.4 Cleaving the Optical Fiber To cleave the fiber you will need the following item from the Tool Kit: • Cleaving tool (G) Caution: Glass fibers are very sharp and can easily pierce the skin. Do not let cut pieces of fiber stick to your clothing or drop in the work area where they can cause injury later. Safely dispose of cleaved or broken pieces of glass fibers. The cleaving process is the same for both 3 mm and 900 micron fiber optic cable. Use the following procedure to cleave the fiber: 1. Hold the cleaving tool (G) at about a 30-degree angle to the end of the connector (as shown in Figure 15). 2. Using the cleaving tool, gently place one light scratch on the fiber as close to the ceramic ferrule as possible.
Note: A single light scratch on the fiber produces the best cleave. Do not scratch deeply or saw the fiber with the cleaving tool as this may break off the fiber within the ferrule, ruining the connector. 3. Grasp the end of the fiber and carefully pull it straight up until the fiber breaks at the cleave. Do not bend the fiber over to break it or the fiber may crack below the surface of the ceramic ferrule. If the fiber does not separate easily, re-cleave the fiber (step b). 4. Dispose of the fiber end by immediately placing it in a trash container. Do not let pieces of fiber stick to your clothing or drop into the work area where they might cause injury later.

2.7 Polishing the Optical Fiber The same polishing process applies to both 3 mm and 900 micron fiber optic cable. To polish the fiber you will need some water plus the following items from the Tool Kit (in the order listed): • Gray (5 µm silica carbide) polishing film (H) • Brown (6 µm diamond) polishing film (I) • Purple (1 µm diamond) polishing film (J) • White (0.5 µm cerium oxide) polishing film (K) • Water bottle (Q) • Tissue wipe (M) 1. Remove the Hackle (or Burr) With the GRAY Polishing Film Note: The abrasive side of the polishing paper has a matte (or rough) finish; the shiny side should face away from the connector. a. Use a sheet of GRAY (5 micron silica carbide) polishing film (H) to remove the hackle or burr from the end of the fiber as shown in Figure 18. Hold the matte or dull side of the polishing film against the end face of the ceramic ferrule (while exerting light downward pressure), then move the film in a circular pattern until the fiber is polished down to the adhesive. The circle size should be approximately one-half that of the sheet of polishing film. When the hackle is removed, the polishing sound will start out as a scratching sound and then change noticeably. Note: Each sheet of GRAY polishing film can be reused to remove the hackle from up to 5 connectors before requiring replacement.

2. Polish the Fiber on the BROWN (6 Micron Diamond) Polishing Film a. Remove polishing surface (T) from its storage location and place it on a flat surface; then apply a 1/2 inch diameter drop of water to the shiny side of the polishing surface (T). Place one sheet of the BROWN polishing film (I), shiny side down, on the polishing surface as shown in Figure 19. Note: Each sheet of polishing film can be used to polish approximately five connectors. However, before reusing the polishing film, wipe it with an alcohol tissue wipe, (S) until clean. Note: Before each use, clean the polishing film using water and a tissue wipe. b. Screw the connector into the the polishing puck (P), as shown in Figure 19, until the connector can no longer be turned. c. Apply a one-inch (diameter) drop of water to the brown polishing film, then place the connector/puck assembly on the brown (6 micron) polishing film and water. d. Move the connector/puck assembly in a figure-eight motion (over the entire surface of the sheet, see Figure 19). Start with very light downward force on the connector for the first 3 or 4 figure-eights, then gradually increase the force until the polishing puck rides flush against the polishing surface. A total of 50 figure-eights should be made. When finished, remove the brown polishing film from the polishing surface. Note: If the fiber digs into the polishing film, immediately decrease the pressure on the connector or the fiber may chip or break. e. While the connector is still mounted in the puck, clean the ferrule endface.

Apply a 1/2 inch (diameter) drop of water to the back of one sheet of the PURPLE polishing film (J). Place the film, shiny side down, on the polishing surface as shown in Figure 19. b. Apply a one-inch (diameter) drop of water to the purple polishing film, then place the connector/puck assembly on the purple polishing film. c. Move the connector and puck in a figure-eight motion (see Figure 19). Use enough force to cause the puck to ride flush against the polishing surface. Complete approximately 25 figure eights on the purple polishing film. When finished, remove the purple polishing film from the polishing surface. d. While the connector is still mounted in the puck, clean the ferrule endface.
4. Polish the Fiber on the White (0.5 Micron Cerium Oxide) Polishing Film Note: Before each use, clean the polishing film using water and a tissue wipe. a. Apply a 1/2 inch diameter drop of water to the back of one sheet of the WHITE (0.5 micron) polishing film (K). Place the film, shiny side down, on the polishing surface as shown in Figure 19. b. Apply a one-inch (diameter) drop of water to the white polishing film, then place the connector/puck assembly on the white polishing film. c. Move the connector and puck in a figure-eight motion (see Figure 19). Use enough force to cause the puck to ride flush against the polishing surface. Complete EXACTLY 5 figure eights on the white polishing film. When finished, remove the white polishing film from the polishing surface. d. Remove the connector assembly from the polishing puck.
2.8 Cleaning and Inspection To clean and inspect the fiber you will need the following items from the Tool Kit (in the order listed): • An alcohol wipe (S) • A dry tissue wipe (M) And, if possible: • A microscope capable of 200x magnification • A power meter or OTDR After polishing is completed, inspect the connector (ferrule) end face to verify that the fiber is not damaged. Use the following procedure to clean and inspect the fiber end face: 1. Clean the Connector a. Clean the end face of the fiber by wiping several times across the end of the ferrule with an alcohol wipe (S). Note: The alcohol pad should be used to clean several connectors before it is discarded. The kit includes only enough alcohol wipes for two per connector. b. Wipe the end face of the ferrule with a dry tissue wipe (M).

2. Visual Inspection of Connector Endface a. Clean the endface of the connector before viewing; if a defect can be removed with additional cleaning, it is no longer considered to be a defect. b. View the connector endface at 200x or more magnification. Note: On Figures 20 and 21, the area around the outer band is the ceramic ferrule, the outer band (50 microns wide) is the “contact area” of the ceramic ferrule; the middle band (approximately 125 microns in diameter) is the cladding, and the small circle in the middle (approximately 10 microns in diameter) represents the optical core. c. A maximum of two defects are allowable on an acceptable connector. Each of the following (on Figure 20) is considered to be a separate defect: • A maximum of TWO ferrule voids, outside the ferrule contact zone, that are less than 40 microns in length, width, or diameter (as shown at the top of Figure 20). • Coarse polishing marks (less than 5 microns wide) outside the contact zone on the ceramic ferrule (as shown on the left side of Figure 20). • A single ferrule void, within the contact zone, that is less than 20 microns in length, width, or diameter (as shown at the top of the contact zone in Figure 20). • A cleaving chip extending 10 microns or less into the cladding (as shown on the left side of the cladding in Figure 20). • A maximum of TWO light polishing marks (less than one micron wide) in the cladding or contact zone as shown in the lower portion of the contact zone and cladding of Figure 20. • A maximum of THREE small pits or chips (smaller than 5 microns) in the cladding area only (as shown in the top portion of the cladding in Figure 20). • Small chips (less than 10 microns in diameter) along edges of the fiber where the inner diameter of the ferrule hole/capillary is noticeably larger than the outside diameter of the fiber cladding (as shown on the right side of the cladding in Figure 20). (d) Any of the following defects on the connector endface (as shown in Figure 21) are unacceptable: • Dirt, lint, or other contaminants on either the fiber or the ferrule (as shown at the top of Figure 21). • Any single void larger than 40 microns in length, width or diameter in the ceramic ferrule outside the contact zone (as shown in the lower right portion of Figure 21). • A single ferrule void, within the contact zone, that is more than 20 microns in length, width, or diameter (as shown at the top of the contact zone in Figure 21). • A cleaving chip extending 10 microns or more into the cladding (as shown on the left side of the cladding in Figure 21). • Any scratches (wider than one micron) in the cladding or contact zone as shown in the lower portion of the contact zone and cladding of Figure 21. • Any clusters of small pits, scratches, or wavy indentations in the cladding area (as shown on the right side of the cladding in Figure 21). • Any epoxy or other non-removable material on the core, cladding, or contact zone (as shown on the right side of the cladding in Figure 21). • Any cracks in the fiber (as shown on the right side of the cladding in Figure 21).

SUPPORT
3.1 Troubleshooting If you have a problem installing an ADC FasTerm Singlemode FC connector, consult Table 4 for possible solutions. For additional product information or service, call, write or fax ADC’s customer support services (see Section 4). Table 4. Troubleshooting Guide PROBLEM
CAUSE
SOLUTION
Fiber chipped or cracked into the core, evidenced by no definition of the core.
The fiber was scratched too deeply with the cleaving tool.
When cleaving the fiber a light scratch is all that is necessary. Do not use cleaving tool to saw through fiber. Look at fiber after each step in order to ascertain which step is breaking the fiber.
The fiber broke during polishing with either the gray or the brown polishing film.
Excessive pressure was applied.
Apply gentle pressure with the gray polishing film when removing hackle and at beginning of polishing, apply extra pressure gradually until hackle is polished down to the adhesive. Be sure that the hackle has been completely polished down to the adhesive before moving on to the brown polishing film. Allow a larger spot of adhesive to appear on the connector endface when filling connector. Apply accelerator straight onto endface, so adhesive is not blown off endface. The adhesive serves to support the fiber.
Debris on the polishing film or connector.
Clean the polishing film with a connector tissue wipe.
Fiber has not been sufficiently cleaned, or stripped. A tiny piece of debris or residue on the fiber will make it difficult to insert the fiber into the connector.
Clean the fiber before inserting it into the connector. Inspect the fiber for debris before inserting it into connector. Re-strip the fiber.
Adhesive has become hard.
Using a new connector, shorten the time between filling the connector and inserting the fiber.
Trying to strip too much buffer at once.
Strip a shorter length of buffer, taking several short sections rather than, a few long sections of buffer.
Fiber does not go into connector.
Fiber breaks during stripping or fiber buffer pulls out of jacket.
