Description

Modultech 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. Modultech 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.
