        Notes:

        Plug Seq.:Pin engagement sequence during hot plugging.

1)TX Fault 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 a laser fault of some kind.In the low state,the output will be pulled to less than 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 4.7k~10kΩ resistor.Its states are:

Low(0 to 0.8V):            Transmitter on

(>0.8V,<2.0V):            Undefined

High(2.0 to 3.465V):        Transmitter Disable

Open:                     Transmitter Disabled

3)Mod-Def 0,1,2.These 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 is grounded by the module to indicate 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 wire serial interface for serial ID

4)LOS(Loss of Signal)is an open collector/drain output,which should be pulled up with a 4.7K – 10KΩ 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.

5)RD-/+:These are the differential receiver outputs.They are internally DC-coupled 100 differential lines which should be terminated with 100Ω(differential)at the user SERDES.

6)TD-/+:These are the differential transmitter inputs.They are internally AC-coupled,differential lines with 100Ω differential termination inside the module.
