Fibre Channel host connectors
The Fibr
e Channel FED uses a host connector which is an L
C-type optical tr
ansceiver that
converts electrical signals fr
om the FED to light pulses that are supported by the ber
optic cables. Host connectors are either shortwave or longwave. Fibre Channel FEDs are
congured with shortwave host connectors by default. Longwave host connectors are
available and can be substituted as needed.
The following gure shows the SFP transceiver of a host connector.
