Physical Planning Considerations 5 Cables LC Connectors Fiber-optic jumper cables are required to connect directors, fabric switches, and SAN routers ports to servers, devices, distribution panels, or other elements in a multiswitch fabric or routed SAN. Depending on the attached device and fabric element port, use one of the following types of cable: • Graded-index 62.5/125 micron multimode cable provides a transmission distance of up to 250 meters (1.0625 Gbps), 120 meters (2.1250 Gbps), or 75 meters (10.2000 Gbps) and connects to shortwave ports that transmit light at an 850 nanometer (nm) wavelength. The cable typically has an orange jacket. • Graded-index 50/125 micron multimode cable provides a transmission distance of up to 500 meters (1.0625 Gbps), 300 meters (2.1250 Gbps), or 150 meters (10.2000 Gbps) and connects to shortwave ports that transmit light at an 850 nm wavelength. The cable typically has an orange jacket. • Depending on transceiver type, dispersion-unshifted (step-index) 9/125 micron singlemode cable provides a transmission distance of up to 10, 20, or 35 kilometers and connects to longwave ports that transmit light at a 1300 nm wavelength. The cable typically has a yellow jacket. Multimode or singlemode cables attach to Intrepid-series director, Sphereon-series fabric switch, and Eclipse-series SAN router ports with SFP optical transceivers and LC duplex connectors.
