    1. TD+/- are internally AC coupled with 100Ω differential termination inside the module.
    2. Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kΩ resistors on the host board. Pull up voltage between 2.0V and Vcc+0.3V.

    3.RD+/- outputs are internally AC coupled, and should be terminated with 100Ω (differential) at the user SERDES.

    Notes:

    1.When high, this output indicates a laser fault of some kind. Low indicates normal operation. And should be pulled up with a 4.7 – 10KΩ resistor on the host board.

    1. 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 – 10KΩ resistor. Its states are:

      Low (0 – 0.8V): Transmitter on               (>0.8, < 2.0V): Undefined

      High (2.0V~Vcc+0.3V): Transmitter Disabled   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 between 2.0V~Vcc+0.3V.

           Mod-Def 0 has been 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.When high, this output indicates loss of signal (LOS). Low indicates normal operation.

    5.RD+/-: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board.

    1. TD+/-: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board.
