cost-optimized aggregator-based communications topology for a single point to multiple point network

摘要

It is an optical combiner for a communications network that transmits both upstream and downstream optical signals. The communications network includes an array of amplifiers, each receiving a respective instance of the downstream optical signal. The output of each amplifier is divided into a plurality of ports on a first splitter / combiner unit. the first splitter / combiner unit transmits the downstream amplified optical signal to the respective second splitter / combiner units.
