Optical multimode 3 (OM3) and optical multimode 4 (OM4) cables are available for
open systems host and SRDF connectivity. To obtain OM3 or OM4 cables, contact
your local sales representative.
OM3 cables are used for SRDF connectivity over: 4, 8, and 10 Gb/s Fibre Channel
l
I/O modules, 10 GbE and 1 GbE I/O modules.
OM4 cables are used for SRDF connectivity over 16 Gb/s Fibre Channel I/O
l
modules.
OM4 cables are used with 16 Gb/s Fibre Channel I/O modules to provide Fibre
l
Channel connection to switches. Distances of up to 190 m over 8 Gb/s Fibre
Channel and 125 m over 16 Gb/s Fibre Channel modules are supported.
OM2 or OM3 cables can be used, but distance is reduced.
OM3 cables support 8 and 16 Gb/s Fibre Channel distances up to 150 m or 16 Gb/s
l
Fibre Channel distances up to 100 m.
OM2 cables support 8 Gb/s Fibre Channel distances up to 50 m or 10 Gb/s
l
Ethernet up to 82 m.
Note
OM2 cables can be used, but they will not support 8 Gb/s Fibre Channel (SRDF)
distances greater then 50 m. For longer distances, use OM3 cables.
The following table provides the OM3 and OM4 cables.
