Physical Planning Considerations
136 SAN High Availability Planning Guide
Cables and Connectors
This section provides Fibre Channel cable and connector planning information as
follows:
■ Cables for all directors and switches.
■ SFP transceivers for Director 2/64, Director 2/140, Edge Switch 2/12, Edge
Switch 2/16, Switch 2/24, and Edge Switch 2/32.
Cables
Fiber-optic jumper cables are required to connect director and switch ports to
servers, devices, distribution panels, or other elements in a multi-switch fabric.
Depending on the attached device, director port, or switch port, 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 micron (50/125). The cable provides a transmission
distance of up to 300 meters at 2.125 Gbps and connects to shortwave ports
that transmit light at an 850 nanometer (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 of up to 150 meters at 2.125 Gbps and connects to
shortwave ports that transmit light at an 850 nm wavelength. The cable
typically has an orange jacket.
■ Dispersion-unshifted (step-index) single-mode cable with a core diameter of
nine microns and a cladding diameter of 125 microns (9/125). Depending on
transceiver type, the cable provides a transmission distance of up to 10, 20, or
35 kilometers and connects to longwave ports that transmit light at a 1310 nm
wavelength. The cable typically has a yellow jacket.
HP supplies cables for 10 and 35 kilometers. For longer distances, you need
Fibre Channel repeaters or wave division multiplexing (WDM) devices.
Director and Switch Connectors
Multimode or single-mode cables attach to Director 2/64, Director 2/140, Edge
Switch 2/12, Edge Switch 2/16, Edge Switch 2/24, and Edge Switch 2/32 ports
with SFP transceivers with LC duplex connectors. Figure 54 illustrates an SFP
transceiver and LC duplex connector.
