pulled to < 0.8 V.
When low, this output indicates the received optical power is below
When high, this output indicates normal operation (as defined by the
Low (0 - 0.6 V): Transmitter Enabled
(>0.8, <2.0 V): Undefined
High (2.0 - 3.465 V): Transmitter Disabled
MOD-DEF 1 is the clock line of a 2-wire serial interface for serial ID.
MOD-DEF 2 is the data line of a 2-wire serial interface for serial ID.
Low: Indicates normal operation. In the low state, the output is
High: Indicates a laser fault.
VeeR and VeeT are the signal grounds, there 2 grounds are
internally separated within the SFF module.

SD (Signal Detect) is a TTL output and has an internal 10K pull-up
resistor to VccR.
RD-/+ are the differential receiver outputs. They are AC-coupled
100 W differential lines that are terminated with 100 W
(differential) at the user SerDes. The AC coupling is performed
inside the TXN31015D2 Optical Transceiver and is therefore not
required on the host board.
TX DISABLE is a TTL input used to shut down the transmitter optical
output. The states are as follows:
TD-/+ are the differential transmitter inputs. They are AC-coupled
differential lines with 100 W differential termination inside
TXN31015D2 Optical Transceiver. The AC coupling is performed
inside the TXN31015D2 Optical Transceiver and is therefore not
required on the host board.
MOD-DEF 1, 2: These pins are definition pins for the TXN31015D2
Optical Transceiver. They are pulled up with a 4.7 K - 10 K W
resistor on the host board. Use a pull-up voltage between 2.0 V and
