Cables
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:
•
•
•
LC Connectors
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.

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.
