Finisar Corporation provides optical subsystems and components that are used in data communication and telecommunication applications. The Company�s optical subsystems consist of transmitters, receivers, transceivers, transponders and active optical cables that provide the optical-electrical interface for interconnecting the electronic equipment which rely on the use of semiconductor lasers and photodetectors in with integrated circuits and optoelectronic packaging. The Company supplies optical transceivers and transponders that allow point-to-point communications on a fiber using a single specified wavelength that, bundled with multiplexing technologies, to supply multi-Gbps bandwidth over several wavelengths on the same fiber. The Company provides products known as wavelength selective switches (WSS). WSS are switches used to dynamically switch network traffic from one optical fiber to multiple other fibers without first converting the optical signal to an electronic signal.
