FME fiber-optic multiplexers are suited for synchronous transmission of up to six E1/T1 channels or twelve 48 ¥ 64-kbit/sec channels via stacking. They also support X.21, V.35 and V.36 interfaces and are available for multimode or singlemode cable. The multiplexers are immune to stray electric currents and contribute to the galvanic separation of the connected devices. Switchable loops (V.54, loop 2 and loop 3) are additional tools for troubleshooting. The multiplexers are available as rack-mountable, stand-alone units.
