LED	Status	Description
LINK/ACT	OFF	No link is present.

Interface Cable For SIC-1FEF, select fibers depending on the type of the installed SFP removable optical module. As the interfaces provided by these SFP modules use LC-type fiber-optic connectors, you must use fibers with LC connectors for them.

Figure 60 LC-type fiber-optic connector

n	LC-type fiber-optic connectors are compact fiber-optic connectors developed by
	Lucent. Push an LC-type fiber-optic connector to connect it to the optical module
	and press the button on the connector to remove it.

The fibers are provided depending on the purchased SFPs. Therefore, please provide information on the SFPs when purchasing interface cards; by default, the fibers are not provided.
