Table 2. Pin Description
Notes:
1. TX Fault is an open collector/drain output which should be pulled up externally with a 4.7K – 10 K resistor on the host board to a supply
2. TX disable input is used to shut down the laser output per the state table below. It is pulled up within the module with a 4.7-10 K resistor.
3. Mod-Def 0,1,2. These are the module defi nition pins. They should be pulled up with a 4.7-10 K resistor on the host board to a supply less
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7 K – 10 K resistor on the host board to a
5. RD-/+: These are 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 as 3.135 – 3.465 V at the SFP connector pin. The in-rush current
7. TD-/+: These are the diff erential transmitter inputs. They are AC coupled diff erential lines with 100  diff erential termination inside the module.

supply < VccT,R+0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defi ned by
the standard in use). Low indicates normal operatio0n. In the low state, the output will be pulled to < 0.8 V.
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
must be between 370 and 2000 mV diff erential (185 – 1000 mV single ended) according to the MSA. Typically it will be 1500mv diff erential.
will typically be no more than 30 mA above steady state supply current after 500 nanoseconds.
The AC coupling is done inside the module and is thus not required on the host board. The inputs will accept diff erential swings of 500 – 2400
mV (250 – 1200 mV single ended). However, the applicable recommended diff erential voltage swing is found in Table 5.
Mod-Def 0 is grounded by the module to indicate that the module is present
Mod-Def 1 is clock line of two wire serial interface for optional serial ID
Mod-Def 2 is data line of two wire serial interface for optional serial ID
