Extreme Networks 10018 Connecting Fiber Cables, Remove an SFP Module, 100FX/1000LX SFP Module

Extreme Networks SFP and SFP+ Modules

1Holding the SFP module by its sides, insert the SFP module into the port on the switch.

2Slide the SFP module into the port until you hear it click.

If the SFP module has a handle, push up on the handle to secure the SFP module.

Note

Disconnect fiber-optic cable from an optical SFP module before removing the SFP module from the port.

Connecting Fiber Cables

Before you connect fiber cables to the dual-speed 100FX/1000LX SFP module or the LX100 SFP module, note the following information about these SFP modules

100FX/1000LX SFP Module

The 100FX/1000LX SFP module complies with the 100FX-SMF standard.

In order to use the 100FX/1000LX SFP module in 100FX-MMF operation, a minimum attenuation of 6 dB is required. After the SFP module is installed, connect a 6-dB attenuator to the transmitter side (Tx) of the SFP module. Then connect the attenuator to the single-mode end of a mode conditioning patch cord. The mode conditioning patch cord transitions the SFP module from SMF to MMF operation.

LX100 SFP Module

To prevent permanent damage to the LX100 SFP module, always check the optical input power of the receiver before you insert the fiber cable.

The maximum optical input power is -9 dBm. If you use an optical loopback for diagnostics, the loopback requires a minimum of 12 dB optical attenuation. The recommended attenuation range is 12 to 20 dB.

Remove an SFP Module

1Disconnect the optical cable from the SFP module.

2Unlatch the SFP module in one of the following ways:

a On an SFP module similar to Module A in Optical SFP Module Types and Connectors, press and hold the black plastic tab at the bottom of the connector.

b On an SFP module similar to Module B, Module C, or Module D in Optical SFP Module Types and Connectors, rotate the front handle down.

3Pull the SFP module out of the port on the switch.
