Pin Descriptions

Note1: Module ground pins GND are isolated from the module case.

Note2: The Tx_Fault output is an open collector/drain output, which should be pulled up with a 4.7k to 10k ohms resistor on the host board.  Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates a transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal operation.  In the low state, the output is pulled to <0.8V.

Note3: Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.

Note4: Shall be pulled up with 4.7K-10Kohms to a voltage between 3.15V and 3.45V on the host board.

Note5: LOS is open collector output. Should be pulled up with 4.7-10k ohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic  1 indicates loss of signal.

Note6: VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the SFP+ connector pin.

Note7: They areAC-coupled, differential lines with  100  Ω differential termination inside the module.
