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.
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 – 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.
6. 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.
