Notes:

-INDU SFP (mini Gbic), 1000Mbit, SX/LC, Industrial, -40 - +85°C

1. TX Fault is an open collector output, which should be pulled up with a 4.7k~10kΩ
resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0
indicates normal operation; logic 1 indicates a laser fault of some kind. In the low
state, the output will be pulled to less than 0.8V.

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 4.7k~10kΩ resistor. Its states are:
Low (0~0.8V): Transmitter on
(>0.8V, <2.0V): Undefined
High (2.0~3.465V): Transmitter Disabled
Open: Transmitter Disabled

3. MOD-DEF 0,1,2 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 VccT or VccR.
MOD-DEF 0 is 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. LOS is an open collector output, which should be pulled up with a 4.7k~10kΩ
resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0
indicates normal operation; logic 1 indicates loss of signal. In the low state, the

output will be pulled to less than 0.8V.

5. These are the differential receiver output. They are internally AC-coupled 100Ω
differential lines which should be terminated with 100Ω (differential) at the user senders.

6. These are the differential transmitter inputs. They are AC-coupled, differential lines with
100Ω differential termination inside the module.
