8100 Series Fiber MDAs

The 8100 Series fiber MDAs are used to make fiber-based 100 Mb/s connections to the switch. Two versions of these MDAs are available (Figure C-4):

•The 8100-2FX MDA uses two longwave 1300 nm SC connectors to connect devices over 62.5/125 µm multimode fiber optic cable.

•The 8100-4FX MDA uses four longwave 1300 nm MT-RJ connectors to connect devices over 62.5/125 µm multimode fiber optic cable.

The 8100 Series fiber MDAs are not supported on single-mode fiber cable.
