Description
Baudcom DWDM SFP Transceiver exhibits excellent wavelength stability,
supporting operation at 100 GHz channel, cost effective module. It is designed
for DWDM SONET/ SDH, Gigabit Ethernet and Fiber- Channel applications.
The transceiver consists of two sections: The transmitter section
incorporates a colded DFB laser. And the receiver section consists of a APD
photodiode integrated with a TIA. All modules satisfy class I laser safety
requirements. BAUDCOM DWDM SFP transceiver provides an enhanced monitoring
interface, which allows real-time access to device operating parameters such as
transceiver temperature, laser bias current, transmitted optical power,
received optical power and transceiver supply voltage, laser temperature and
TEC current.

Notes：
1. TX Fault is an open
collector/drain output, which should be pulled up with a 4.7K – 10K. resistor
on the host board. Pull up voltage between 2.0V and VccT, R+0.3V. When high,
output indicates a laser fault of some kind. Low indicates normal operation. In
the low state, the output will be pulled to < 0.8V.
2. TX disable is an
input that is used to shut down the transmitter optical output. It is pulled up
within the module with a 4.7 – 10 K. resistor.
3. These are the module
definition pins. They should be pulled up with a 4.7K – 10K. resistor on the
host board. The pull-up voltage shall be VccT or VccR (see Section IV for
further details).
4. LOS (Loss of Signal)
is an open collector/drain output, which should be pulled up with a 4.7K – 10K.
resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output
indicates the received optical 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.
