Logic High Indicates a laser fault of some kind. TX Fault is an open drain output, which should be pulled up with a 4.7K 1KΩ resistor on the host board. Transmitter Disable 3 TX Disable Its states are: Low (.8V) :Transmitter on (>.8, < 2.V) :Undefined High ( V) :Transmitter Disabled Open :Transmitter Disabled It is pulled up within the module with a 4.7K 1 K.Ω resistor. Module Definition 2 (SDA) The data line of two wire serial interface for serial ID. 4 MODDEF2 MODDEF2 should be pulled up with a 4.7K 1KΩ resistor on the host board. The pullup voltage shall be VccT or VccR. Module Definition 1 (SCL) The clock line of two wire serial interface for serial ID. 5 MODDEF1 MODDEF1 should be pulled up with a 4.7K 1KΩ resistor on the host board.

Transmit Data In (Note 2) 2 VeeT Transmitter Ground Notes: 1. RD+ and RD are AC coupled 1Ω differential lines which should be terminated with 1Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will be between 37 and 2 mv differential (185 1 mv single ended) when properly terminated. 2. TD+ and TD are ACcoupled, differential lines with 1Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 5 24 mv (25 12 mv singleended), though it is recommended that values between 5 and 12 mv differential (25 6 mv singleended) be used for best EMI performance.
