ABSTRACT:
Systems and devices for use as optical transceivers and amplifiers in optical networks. An optical transceiver/amplifier has two optical signal circulators, each of which receives one incoming signal and transmits one outgoing optical signal. Each circulator combines its incoming and outgoing signals on to a bidirectional optical connection internal to the transceiver amplifier. Between the two circulators are a pump laser, an optical coupler to couple the pump laser's power into the bidirectional connection, and an amplifying medium for amplifying the bidirectional signals internal to the transceiver amplifier. The amplifying medium may be an Erbium doped fiber which would amplify any optical signal passing through it. In one embodiment, the transceiver amplifier is in a self-contained package that is pluggable into existing equipment using pre-existing ports and interfaces.
