TRIPLE WAVELENGTH BIDIRECTIONAL OPTICAL COMMUNICATION SYSTEM

摘要

A triple wavelength bidirectional optical communication system includes an optical fiber, a transmitter optical subassembly and a receiver optical subassembly. The transmitter optical subassembly includes a first filter, a dual wavelength laser device and a first detector device. The dual wavelength laser device emits a first and a second laser beam to the optical fiber. The first detector device receives a third laser beam emitted from the optical fiber and propagated via the first filter. The receiver optical subassembly includes a second filter, a transceiver device and a second detector device. The transceiver device emits the third laser beam propagated via the second filter and reached to the optical fiber and also receives the first laser beam emitted from the optical fiber and propagated via the second filter. The second detector device receives the second laser beam emitted from the second facet and propagated via the second filter.
