Finisar Corporation provides optical subsystems and components for data communication and telecommunication applications in the United States, Malaysia, China, and internationally. Its optical subsystems primarily consist of transmitters, receivers, transceivers, transponders, and active optical cables that provide the fundamental optical-electrical or optoelectronic interface for interconnecting the electronic equipment used in communication networks, including the switches, routers, and servers used in wireline networks, as well as the antennas and base stations used in wireless networks. The company also offers wavelength selective switches, which are used to switch network traffic from one optical fiber to multiple other fibers without converting the optical signal to an electronic signal. In addition, it provides optical components comprising packaged lasers, receivers and photodetectors for data communication and telecommunication applications; and passive optical components for telecommunication applications. Finisar Corporation markets its optical products through its direct sales force, as well as through a network of distributors and manufacturers’ representatives to the original equipment manufacturers of storage systems, networking equipment, and telecommunication equipment. The company was founded in 1987 and is headquartered in Sunnyvale, California.
