The transceiver consists of two sections: The transmitter section incorporates a FP or uncooled DFB laser, and the receiver section consists of a PIN photodiode or APD integrated with a trans-impedance preamplifier (TIA). All modules satisfy class I laser safety requirements. The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault is provided to indicate degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver. The transceiver provides an enhanced monitoring interface, which allows real time access to the transceiver operating transceiver temperature, parameters laser bias such as current, transmitted optical power, received optical power and transceiver supply voltage by reading a built-in memory with I2C interface.

It is pulled up within the module with a 4.7k~10kΩ resistor. Its states are: Low (0~0.8V): Transmitter on (>0.8V, <2.0V): Undefined High (2.0~3.465V): Transmitter Disabled Open: Transmitter Disabled 3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10kΩ resistor on the host board. The pull-up voltage shall be VccT or VccR. MOD-DEF 0 grounded by the module indicates that the module is present MOD-DEF 1 is the clock line of two-wire serial interface for serial ID MOD-DEF 2 is the data line of two-wireserial interface for serial ID 4. LOS is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. In the low state, the output will be pulled to less than 0.8V. 5. These are the differential receiver outputs.
