PMX OPMUX-FL100 PDH multiplexer combines four/eight E1 channels and one 10/100M LAN channel over a single fiber optic link. A pair of PMX OPMUX-FL100 offers simple and low-cost connectivity for these E1 and LAN traffic up to 80KM.  OPMUX-FL100 supports 1+1 optical link redundancy with ALS function (Automatic Laser Shutdown/Reduction). PMX OPMUX-FL100 fiber optic Multiplexer can be used to extend the transmission distance without performance degradation via fiber cable between two Fast Ethernet segments transparently.

PMX OPMUX-FL100 has found wide applications in carriers, paging stations, electricity, railway, oil-fields and banks, as point-to-point applications and central-site to multipoint application. Its compact 1-U high enclosure facilitates easy installation and maintenance.
