2. TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the
3. MOD-DEF0,1,2. These are the module definition pins. They should be pulled up with a 4.7K-10KΩ resistor
4. Tx Signal Detect, Tx Active State: High.
5. LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K-10KΩ resistor.
6. These are the differential receiver outputs. They are AC coupled internally, Compatible with LVPECL.
7. V
8.These are the differential transmitter inputs. The DC coupling is done inside the module.

Pull up voltage between 2.0V and V
power is below the worst-case receiver sensitivity (as defined by the standard in use). Low indicates normal
operation. In the low state, the output will be pulled to < 0.8V.
connector pin. Inductors with DC resistance of less than 1Ω should be used in order to maintain the
required voltage at the SFP input pin with 3.3V supply voltage. When the recommended supply filtering
network is used, hot plugging of the SFP transceiver module will result in an inrush current of no more than
30 mA greater than the steady state value.
kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
Low (0-0.8V): Transmitter on
(>0.8, < 2.0V): Undefined
High (2.0-3.465V): Transmitter Disabled
Open: Transmitter Disabled
MOD-DEF0 is grounded by the module to indicate that the module is present
MOD-DEF1 is the clock line of two-wire serial interface for serial ID
MOD-DEF2 is the data line of two-wire serial interface for serial ID
