Cables
Use multimode fiber optic cables with shortwave lasers that adhere to the following specifications:
v OM3 or OM4: 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 only can be connected to other OM1 cables. For best results,
OM2 cables must not be connected to OM3 or OM4 cables. However, if an OM2 cable is connected to an
OM3 or OM4 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 fiber optic cable types at different link
speeds.
