DESCRIPTION
General
The Small Form Factor Pluggable (SFP) series of transceiver modules from Opnext, Inc. are hot
pluggable 3.3V transceivers designed for a range of high-speed bi-directional communication
applications and offer nominal data rates ranging from 155Mbit/s to 2.5 Gbit/sec. Supported
distances range from 500m (Gigabit Ethernet and Fibre Channel multimode) to 80km (155Mbit/s,
622Mbit/s, 2.5Gbit/s SONET/SDH and Gigabit Ethernet). The transceivers are compliant with
all applicable standards, such as the relevant ITU and IEEE specifications, as well as the SFP
Multisource Agreement (Sept. 2000). The SFP transceivers are provided with an LC receptacle
that is compatible with the industry standard LC connector. The transceivers are also compatible
with industry standard electrical connector and cage. The SFP transceivers are Class 1 eye safety
products. The optical output power levels, under normal operation, are at eye-safe level.

Note: VccR and VccT are the receiver and transmitter power supplies. The recommended
host board power supply filtering is described below. When the recommended power
supply filtering network is used, hot plugging the SFP transceiver module will result in an
inrush current of no more than 30mA greater than the steady-state value. VccR and VccT
are not connected internally within the SFP module

lines, which should be terminated with 100Ω (differential) at the user SERDES. The AC
coupling is done inside the module and thus is not required on the host board
Note: This is an open collector/drain output, which should be pulled up with a 4.7 kΩ –
10 kΩ resistor. Pull-up voltage between 2.0V and VccT,R + 0.3V. When high, this output
indicates the received power is below the worst-case receiver sensitivity (as defined by the
standard in use). Low indicates normal operation. In the low state, the output will be
pulled to <0.8V
