Fiber optic Fibre Channel cables
The Enterprise Virtual Array uses orange, 50-µm, multi-mode, fiber optic cables for connection to the
SAN or the host, where there is a direct connection to the host. The fiber optic cable assembly consists
of two 2-m fiber optic strands and small form-factor connectors on each end. See
Figure 6
.
To ensure optimum operation, the fiber optic cable components require protection from contamination
and mechanical hazards. Failure to provide this protection can cause degraded operation. Observe
the following precautions when using fiber optic cables.
•
To avoid breaking the fiber within the cable:
• Do not kink the cable
• Do not use a cable bend-radius of less than 30 mm (1.18 in)
•
To avoid deforming, or possibly breaking the fiber within the cable, do not place heavy objects
on the cable.
•
To avoid contaminating the optical connectors:
• Do not touch the connectors
• Never leave the connectors exposed to the air
• Install a dust cover on each transceiver and fiber cable connector when they are disconnected
If an open connector is exposed to dust, or if there is any doubt about the cleanliness of the connector,
clean the connector as described in

Copper Fibre Channel cables
The Enterprise Virtual Array uses copper Fibre Channel cables to interconnect disk shelves. The cables
are available in 0.6-meter (1.97 ft.) and 2.0-meter (6.56 ft.) lengths. Copper cables provide
performance comparable to fiber optic cables. Copper cable connectors differ from fiber optic small
form-factor connectors (see
Figure 7
).
