Copper SFP+ Series
The number of JCP-SFP-RJ45 needs to be determined according to the power supply capability ofequipment.
Make sure the air flow is well for SFP in equipment.
Leave the adjacent port empty if possible.
Note3. TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within
the module with a 4.7 – 10 KΩ resistor. Its states are:Low (0 – 0.8V): Transmitter on(>0.8, < 2.0V): UndefinedHigh (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter DisabledNote2
Note4. Mod-Def 0,1,2. These 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.
