Abstract
The telecommunications network node linking a metropolitan area network, including at least one optical link connecting the nodes, with at least one access network, includes an electronic card that enables the aggregation of traffic from multiple access networks, a transmitter capable of receiving an electrical signal from the electronic card and of transmitting an optical packet to the metropolitan area network, a circulator capable of extracting a stream of multiplexed optical packets from the optical link and of inserting a stream of multiplexed optical packets into the optical link, and a reflective switching matrix receiving a stream of multiplexed optical packets from among which it selects and detects those intended for the access network. The reflective switching matrix includes a POADM optical packet add/drop multiplexer that receives multiplexed optical packets and transmits demultiplexed optical packets, and at least one RSOA reflective semiconductor optical amplifier capable of receiving a demultiplexed optical packet, which includes three sections.
