There are two 100BASE-FX models ( Figure C-2 ):
• 400-2FX MDA
The 400-2FX MDA uses two longwave 1300 nm SC connectors to attach
devices over 62.5/125 or 50/125 micron multimode fiber optic cable.
• 400-4FX MDA
The 400-4FX MDA uses four longwave 1300 nm MT-RJ connectors to attach
devices over 62.5/125 or 50/125 micron multimode fiber optic cable.
Figure C-2. 100BASE-FX MDA Front Panels
Both models conform to the IEEE 802.3u 100BASE-FX standard and can be used
for fiber-based 100 Mb/s connections (2 km/6562 ft maximum distance) to other
compatible Fast Ethernet devices. Single-mode fiber cable is not supported.
Table C-2 describes the 100BASE-FX components and LEDs.
