be ordered separately.
For cables measuring up to 500 meters (1 Gbps) or 300 meters (2 Gbps), use
multi-mode Fibre Channel cables. For longer cables, use single-mode Fibre
Channel cables.
Multi-mode optical cables are connected to short-wave optical transceiver
modules in a switch. Single-mode optical cables are connected to long-wave
optical transceiver modules in a switch. Multi-mode cables should use 50/125
optical fibers, and single-mode cables typically use 9/125 optical fibers for
distances up to 10 km.
Verify that connectors interfacing with the Director 2/64 and Director 2/140 use
LC Duplex connectors with a PC finish. In addition, the connector at the opposite
end of the cable must use either LC or SC type, depending on the requirements of
the connected device.

least two ISLs should connect any two director-class fabric elements. Because
this number is subject to change, contact your HP authorized service
representative for the current number of ISLs supported per director.
Hop Count—The fibre channel theoretical limit of ISL connections traversed
(hop count) in a single path through a fabric is 7. The maximum supported
hop count in a single path through a fabric is 3. Because this number is subject
to change, contact your HP authorized service representative for the current
hop count supported by a single fabric path.
The hop count is equal to the number of ISL connections traversed in a single
