Abstract

See full text

An optical circulator integrated into a transceiver for bi-directional communication may include a core configured to pass a transmission signal in a transmit direction and a received signal in a receive direction. The optical circulator may include an input port optically coupled to the core. The input port may be configured to deliver the transmission signal to the core. The optical circulator may include an output port optically coupled to the core. The output port may be configured to receive the received signal from the core. The optical circulator may additionally include a network port optically coupled to the core. The network port may be configured to receive the transmission signal from the core and deliver the transmission signal to a fiber optic cable. The network port may be configured to receive the received signal from the fiber optic cable and deliver the received signal to the core.
