Fiber-Optic Network Interface Cables
The ATM line cards have SC-type fiber-optic interface connectors. Use a multimode or single-mode
fiber-optic interface cable, as appropriate, to connect the fiber-optic interfaces in the ATM line card in
your Cisco 12000 series router to another router or switch. In general, multimode cables are gray or
orange, and single-mode cables are yellow.
Single-mode and multimode fiber-optic cables are available from cable vendors. These cables are not
Note
available from Cisco Systems. The plug on the cable may be supplied with a dust cover. If it is, remove
it before trying to connect it to the line card port.
You can use either one duplex SC-type connector
