Transmitter Ground¹⁾
1) _{Common transmitter and receiver ground within the module.}
2) _{A high signal indicates a laser fault of some kind and that laser is switched off.}
3) _{A low signal switches the transmitter on. A high signal or when not connected switches the transmitter off.}
4) _{MOD-DEF(2) is the data line of two wire serial interface for serial ID.}
5) _{MOD-DEF(1) is the clock line of two wire serial interface for serial ID.}
6) _{MOD-DEF(0) is grounded by the module to indicate that the module is present.}
7) _{A low signal indicates normal operation, light is present at receiver input. A high signal indicates the received}
optical power is below the worst case receiver sensitivity.
8) _{Should be pulled up on host board to VCC by 4.7 - 10 kΩ.}
9) _{AC coupled inside the transceiver. Must be terminated with 100 Ω differential at the user SERDES.}
10) _{AC coupled and 100 Ω differential termination inside the transceiver.}
