Cabling and Specifications
• Single-mode—Generally yellow in color.
• Multimode—Generally gray or orange in color. Multimode cables are multifiber cables that carry
12 channels of fiber data.
Note For network applications using CWDM GBICs in Ethernet line cards, the CWDM GBICs use SMF patch
cords only. Verify that all your patch cords are yellow (SMF), rather than orange (MMF).
The following types of cable connectors are used with Ethernet line cards:
• Subscriber connector (SC)—See Figure 36 and Figure 37
• Lucent connector (LC)— See Figure 38 and Figure 39
You can use two cables with simplex connectors, or one cable with dual, keyed connectors.
Warning
Invisible laser radiation can be emitted from the aperture of the port when no cable is connected.
Avoid exposure to laser radiation and do not stare into open apertures.
