3. The signals Mod-Def 0, 1, 2 designate the two wire serial interface pins. They must be pulled up with a 4.7 k – 10 k resistor on the host board.
4. RX_LOS (Rx Loss of Signal) is an open collector/drain output that must be pulled up with a 4.7 k – 10 k resistor on the host board. When high, this
5. RD-/+ designate the diff erential receiver outputs. They are AC coupled 100  diff erential lines which should be terminated with 100  diff erential
6. VccR and VccT are the receiver and transmitter power supplies. They are defi ned at the SFP connector pin. The maximum supply current is 300 mA
7. TD-/+ designate the diff erential transmitter inputs. They are AC coupled diff erential lines with 100  diff erential termination inside the module.

Notes:
1. TX_FAULT is an open collector/drain output, which must be pulled up with a 4.7 k – 10 k resistor on the host board. When high, this output
2. TX_DISABLE is an input that is used to shut down the transmitter optical output. It is internally pulled up (within the transceiver) with a 6.8 k

Low (0 – 0.8 V):
Between (0.8 V and 2.0 V):
High (2.0 – Vcc max) or OPEN:
Mod-Def 0 is grounded by the module to indicate the module is present
Mod-Def 1 is serial clock line (SCL) of two wire serial interface
Mod-Def 2 is serial data line (SDA) of two wire serial interface

between 370 and 850 mV diff erential (185 – 425 mV single ended) when properly terminated.
and the associated in-rush current will typically be no more than 30 mA above steady state after 2 microseconds.
The AC coupling is done inside the module and is not required on the host board. The inputs will accept diff erential swings of 180 – 1200 mV
