Cables
Cables are the responsibility of the customer. Use multimode fiber optic cables with shortwave
lasers that adhere to the following specifications:
v OM3: Multimode 50/125 micron fiber, 2000 MHz x km bandwidth
v OM2: Multimode 50/125 micron fiber, 500 MHz x km bandwidth
v OM1: Multimode 62.5/125 micron fiber, 200 MHz x km bandwidth
Because core sizes are different, OM1 cables can only be connected to other OM1 cables. For best
results, OM2 cables must not be connected to OM3 cables. However, if an OM2 cable is connected
to an OM3 cable, the characteristics of the OM2 cable apply to the entire length of the cables.
The following table shows the supported distances for the different cable types at the different
link speeds.
