module with a 4.7-10 KΩ resistor. Its states are:

Low (0-0.8V): Transmitter on

(>0.8, < 2.0V): Undefined

High (2.0-3.465V): Transmitter Disabled

Open: Transmitter Disabled

Note 3: MOD-DEF0,1,2. These are the module definition pins. They should be pulled up with a 4.7K-10KΩ resistor

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

Note 4: Reserved for module tuning and compulsive for system designer that any circuit doesn’t be connected to it.

Note 5: LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K-10KΩ resistor.

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. Maximum supply current is 300 mA. Recommended host board power supply filtering is

shown in figure 4. 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.

Note 7: These are the differential receiver outputs. They are DC coupled 100 Ω differential lines which should be

Note 8: These are the differential transmitter inputs. They are AC coupled differential lines with 100Ω differential

termination inside the module. The AC coupling is done inside the module and is thus not required on the
