FMUX01A/Plus 100M PDH Fibre Optic Multiplexer

16 Channel E1/T1, Data, Voice Plus 100M Ethernet MultiplexerEnd of Life

The FMUX01A/Plus is a 1U, 19" rack mountable, PDH fibre optic multiplexer that transmits up to 16 channels plus a wire speed 100Base-TX Fast Ethernet channel over a single fibre optic link. The FMUX01A/Plus chassis is available in five different power configurations: single AC, single DC, dual AC, dual DC or AC+DC. The AC supplies operate from 90~260VAC while DC supplies operate from 36~72VDC or 20~60VDC. From the rear of the chassis, one to four hot swappable quad E1 or T1 line cards, serial data communications (V.35, X.21, RS-530) or FXO/FXS voice cards are supported. The standard FMUX01A/Plus configuration may be viewed or set via the front panel LCD/menu keys, serial VT-100 terminal connection, Telnet or SNMP.
