-RADIANTECHFiber Optic Small Form Factor
VFD-3143-G
Multimode 850 nm Pluggable Optical Transceiver for 1.063 GBd Fibre Channel / 1.25 Gigabit Ethernet with Digital Diagnostic Function and VF-45TM (SG) Connector
Product Description The
VFD-3143-G
transceiver
Physical-Medium-Dependent
is
sublayer
based and
on
the
baseband
medium type 1000BASE-SX (short wavelength) and Fibre Channel (100-M5-SN-I and 100-M6-SN-I). It conforms to the SFF-8472 Small Form Factor Pluggable (SFP) Multi-Source Agreement (MSA). The appropriate fiber optic cable is 50 µm multimode fiber with the VF-45™ (SG) connector.
FEATURES • Small Form Factor Pluggable (SFP) Multi-Source Agreement (MSA) compliant
The VFD-3143-G transceiver is a single unit comprised of a transmitter, a receiver, and a SG/VF-45™ receptacle. This
• SFF-8472 MSA Compliant (Digital Diagnostic Monitoring
transceiver supports the innovative Volition connectorization concept and is compatible with RJ-45 style backpanels for
Function included) • Fibre Channel (100-M5-SN-I, 100-M6-SN-I) compliant

• Single power supply (3.3 V)
advantages of fiber optic technology. This SFP transceiver is
• ESD Class 2 per MIL-STD 883D Method 3015.7
specially developed for distances of up to 550 m / 2km with
• FCC (Class B) and EN 55022 Compliant • For distances up to 550 m / 2 km with 50/125 µm OM2 / OM3 multimode fibers
applications
while
providing
the
50/125 µm OM2 / OM3 multimode fibers. The module is designed for LAN, SAN, WAN, and Gigabit Ethernet applications. It can be used as the network and
• VF-45™ (SG) connector system
device interface in mainframes, workstations, servers, and
• RoHS Compliant
storage devices, and in a broad range of network devices such as bridges, routers, hubs, and local and wide area switches.
APPLICATIONS • Fiber-to-the-desktop
This SFP transceiver operates at 1.25 Gbits per second from
• Switches/bridges/routers/server
a single power supply (+3.3 V). A Serial EEPROM in the
• Local area networks (LAN)
transceiver provides the transceiver-unique information,
• Storage area networks (SAN)
through the 2-wire serial CMOS E PROM protocol.
• High speed computer links

Comments
Electrostatic Discharge (ESD) to the Electrical Pins

Class 1(>1000V)
Immunity: Electrostatic Discharge (ESD) to the Duplex VF-45 Receptacle
EN 61000-4-2 IEC 1000-4-2
Discharges of ±15kV with an air discharge probe on the receptacle cause no damage.
Immunity: Radio Frequency Electromagnetic Field
EN 61000-4-3 IEC 1000-4-3

Emission: Electromagnetic Interference (EMI)
FCC Class B EN 55022 Class B CISPR 22
Noise frequency range: 30 MHz to 5 GHz
LASER SAFETY This VFD-3143 transceiver is a Class 1 laser product. It complies with IEC 60825-1 and FDA 21 CFR 1040.10 and 1040.11. The transceiver must be operated under recommended operating conditions. Because the transceiver design is designed to be inherently eye safe, it does not require open fiber control thus eliminating complex electronics or mechanics. Caution The use of optical instruments with this product will increase eye hazard! General Restrictions Classification is valid only if the module is operated within the specified temperature and voltage limits. The system using the module must provide power supply protection that guarantees that the system power source will cease to provide power if the maximum recommended operation limit or more is detected on the +3.3 V at the power source. The case temperature of the module must be in the temperature range given in the recommended operating limits. These limits guarantee the laser safety. Usage Restrictions The optical ports of the modules shall be terminated with an optical connector or with a dust plug. Note Failure to adhere to the above restrictions could result in a modification that is considered an act of “manufacturing,” and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (ref. 21 CFR 1040.10 (i))
