The Quad Fibre Loop Converter* (QFLC) system is a cost-effective optical multiplexer that
transports four E1s over two singlemode fibres. The QFLC system can be configured to maximize
facility utilization for point-to-point or point-to-multipoint topologies.
The QFLC system can also be used for fibre ring networks for both dual-feed and single-feed
applications to a customer. The QFLC system accepts standard electrical E1 signals and can be
used in a stand-alone configuration with any approved multiplexer or network element that
generates a standard E1 (6.703 Mbps) signal. The QFLC system consists of a rack mount central
exchange (CE) chassis with up to eight QFLC modules. Sixteen protected...
