1.25 Gbps SFP 1310 nm, 40km, Transceiver with Digital Diagnostics PL-XPL-LC-L13-xx The 1G long wavelength, Small Form Factor Pluggable (SFP) transceiver is part of Picolight’s family of E x t e n s u s products designed for single mode applications. With extended reach capability to 40km, the module satisfies a broad range of intermediate to long distance applications. The 1G SFP transceiver features an uncooled Distributed Feedback (DFB), 1310 nm, highspeed edge-emitting laser coupled to a LC optical connector. Its small size allows for high-density board designs that, in turn, enable greater total aggregate bandwidth. The pluggability of the module further allows manufacturers to configure systems later in the build cycle, providing just-in-time inventory and cost control.
Key benefits • Compliant with industry-wide physical and optical specifications • High reliability • Enables higher port densities

Section 1
Functional description
The PL-XPL-LC-L13-xx transceiver is designed to transmit and receive 8B/10B encoded serial optical data over 9/125 µm optical fiber.
Transmitter The transmitter converts 8B/10B encoded serial PECL electrical data into serial optical data. Transmit data lines (TD+ & TD-) are internally AC coupled with 100 Ω differential termination. An open collector compatible Transmit Disable (TDis) is provided. This pin is internally terminated with a 4.7kΩ − 10kΩ resistor to VccT. A logic “1,” or no connection on this pin will disable the laser from transmitting. A logic “0” on this pin provides normal operation. The transmitter has an internal PIN monitor diode that is used to ensure constant optical power output across supply voltage and temperature variations. An open collector compatible Transmit Fault (TFault) is provided. The Transmit Fault signal must be pulled high on the host board for proper operation. A logic “1” output from this pin indicates that a transmitter fault has occurred, or the part is not fully seated and the transmitter is disabled. A logic “0” on this pin indicates normal operation.
Receiver The receiver converts 8B/10B encoded serial optical data into serial PECL electrical data. Receive data lines (RD+ & RD-) are internally AC coupled and must be terminated with a 100 Ω differential load. An open collector compatible Loss of Signal is provided. The LOS must be pulled high with a resistor (10 kΩ) on the host board for proper operation. A logic “0” indicates that light has been detected at the input to the receiver. (See Section 3.4, “Optical characteristic”, Loss of Signal Assert/Deassert Level on page 9.) A logic “1” output indicates that insufficient light has been detected for proper operation. Power supply filtering is recommended for both the transmitter and receiver. Filtering should be placed on the host assembly as close to the Vcc pins as possible for optimal performance. Recommended “Application Schematics” are shown in Figure 2 on page 5.

Factor Commitee’s document number SFF-8472 Rev 9.5, dated June 1, 2004 for memory/address organization of the digital diagnostic data. The optional enhanced digital diagnostics feature monitors five key transceiver parameters which are Externally Calibrated and should be read as 2’s complement Analog to Digital Values and interpreted as follows using the external calibration constants in bytes A2h (56-91) and the Analog to Digital (AD) values in bytes A2h (96-105); see Table 5 for address descriptions. Transceiver Temperature in degrees Celsius: Internally measured as junction temperature of monitoring IC. Represented as a 16 bit signed two’s complement value in increments of 1/256 degrees Celsius from -40 to +125°C with LSB equal to 1/256 degrees C. Accuracy is ± 3 degrees Celsius over the specified operating temperature and voltage range. T = Tslope*TAD + Toffset Vcc/Supply Voltage in Volts: Internally measured. Represented as a 16 bit unsigned integer with the voltage defined as the full 16 bit value (0-65535) with LSB equal to 100µV with a measurement range of 0 to +6.55V. Accuracy is ± 3% of nominal value over the specified operating temperature and voltage ranges. V= Vslope*VAD + Voffset TX Bias Current in µΑ: Represented as a 16 bit unsigned integer with current defined as the full 16 bit value(0-65535) with LSB equal to 2µΑ with a measurement range of 0 - 131mA. Accuracy is ± 10% of nominal value over the specified operating temperature and voltage ranges. I=Islope*IAD + Ioffset TX Output Power in mW: Represented as a 16 bit unsigned integer with the power defined as the full 16 bit value (0-65535) with LSB equal to 0.1µW. Accuracy is ± 3dB over the specified temperature and voltage ranges over the permitted range of 100µW to 800µW ( -4.5dBm to 0dBm). Data is not valid when transmitter is disabled. TP=TPslope*TPAD + TPoffset RX Received Optical Power in mW: Represented as OMA as a 16 bit unsigned integer with the power defined as the full 16 bit value(0-65535) with LSB equal to 0.1µW.

Reading the data The information is accessed through the MOD_DEF(1), and MOD_DEF(2) connector pins of the module. The specification for this EEPROM (ATMEL AT24CO1A family) contains all the timing and addressing information required for accessing the data. The device address used to read the Serial ID data is 1010000X(A0h), available on all SFP part numbers, and the address to read the diagnostic data is 1010001X(A2h), on PL-XPL-xx-L1x-2x part numbers. Any other device addresses will be ignored. Refer to Table 3, Table 4, and Table 5 for information regarding addresses and data field descriptions MOD_DEF(0), pin 6 on the PL-XPL-LC-L13-xx transceiver, is connected to Logic 0 (Ground) on the transceiver. MOD_DEF(1), pin 5 on the PL-XPL-LC-L13-xx transceiver, is connected to the SCL pin of the EEPROM.

Package and handling instructions
Process plug The PL-XPL-LC-L13-xx is supplied with a dust cover. This plug protects the transceiver’s optics during standard manufacturing processes by preventing contamination from air borne particles. Note:
It is recommended that the dust cover remain in the transceiver whenever an optical fiber connector is not inserted.
Recommended cleaning and de-greasing chemicals Picolight recommends the use of methyl, isopropyl and isobutyl alcohols for cleaning. Do not use halogenated hydrocarbons (e.g. trichloroethane, ketones such as acetone, chloroform, ethyl acetate, MEK, methylene chloride, methylene dichloride, phenol, N-methylpyrolldone).
Flammability The PL-XPL-LC-L13-xx housing is made of plastic and sheetmetal.
4.3
ESD discharge (ESD)
Handling Normal ESD precautions are required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from packaging and handled only in an ESD protected environment utilizing standard grounded benches, floor mats, and wrist straps.
Test and operation In most applications, the optical connector will protrude through the system chassis and be subjected to the same ESD environment as the system. Once properly installed in the system, this transceiver should meet and exceed common ESD testing practices and fulfill system ESD requirements. Typical of optical transceivers, this module’s receiver contains a highly sensitive optical detector and amplifier which may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event might require that the application re-acquire synchronization at the higher layers (e.g. Serializer/Deserializer chip).
4.4
Eye safety The PL-XPL-LC-L13-xx is an international Class 1 laser product per IEC 825-2: 1997, and per CDRH, 21 CFR 1040 Laser Safety Requirements. The PL-XPL-LC-L13-xx is an eye safe device when operated within the limits of this specification. Operating this product in a manner inconsistent with intended usage and specification may result in hazardous radiation exposure.
CAUTION! Tampering with this laser based product or operating this product outside the limits of this specification may be considered an act of “manufacturing,” and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (21 CFR 1040).
