Cabling and Connectors Each FPM card provides four SFP optic transceivers with duplex LC connectors for attaching fiber-optic jumper cables. Figure 14 illustrates an SFP transceiver and duplex LC connector. Figure 14 SFP Transceiver and LC Duplex Connector Fiber-optic jumper cables are required to connect director ports to servers, devices, distribution panels, or other directors in a multiswitch fabric. Depending on the FPM card configuration, use one of the following types of cable: • Graded-index multimode cable with a core diameter of 50 microns and a cladding diameter of 125 microns (50/125). The cable provides a transmission distance between two and 500 meters, and connects to shortwave ports that transmit light at an 850 nanometers (nm) wavelength. The cable typically has an orange jacket. • Graded-index multimode cable with a core diameter of 62.50 microns and a cladding diameter of 125 microns (62.5/125). The cable provides a transmission distance between two and 175 meters, and connects to shortwave ports that transmit light at an 850 nm wavelength. The cable typically has an orange jacket. • Dispersion-unshifted singlemode cable with a core diameter of nine microns and a cladding diameter of 125 microns (9/125). The cable provides a transmission distance between two meters and 10 kilometers, and connects to longwave ports that transmit light at a 1300 nm wavelength. The cable typically has a yellow jacket. 58 Port Connectivity and Fiber-Optic Cabling

Port Connectivity and Fiber-Optic Cabling
Cabling and Connectors
Each FPM card provides four SFP optic transceivers with duplex LC connectors for
attaching fiber-optic jumper cables. Figure 14 illustrates an SFP transceiver and duplex LC
connector.

SFP Transceiver and LC Duplex Connector
Fiber-optic jumper cables are required to connect director ports to servers, devices,
distribution panels, or other directors in a multiswitch fabric. Depending on the FPM card
configuration, use one of the following types of cable:
•
Graded-index multimode cable with a core diameter of 50 microns and a cladding
diameter of 125 microns (50/125). The cable provides a transmission distance between
two and 500 meters, and connects to shortwave ports that transmit light at an 850
nanometers (nm) wavelength. The cable typically has an orange jacket.
•
Graded-index multimode cable with a core diameter of 62.50 microns and a cladding
diameter of 125 microns (62.5/125). The cable provides a transmission distance between
two and 175 meters, and connects to shortwave ports that transmit light at an 850 nm
wavelength. The cable typically has an orange jacket.
•
Dispersion-unshifted singlemode cable with a core diameter of nine microns and a
cladding diameter of 125 microns (9/125). The cable provides a transmission distance
between two meters and 10 kilometers, and connects to longwave ports that transmit
light at a 1300 nm wavelength. The cable typically has a yellow jacket.
