Finisar Corporation engages in the design, development, manufacture, and sale of optical subsystems and components for use in fiber optics-based data communication and telecommunication networks applications. Its optical subsystems primarily consist of transmitters, receivers, transceivers, transponders, and active optical cables principally based on the gigabit Ethernet, fiber channel, OTN, and SONET/SDH protocols that provide the fundamental optical-electrical or optoelectronic interface for interconnecting the electronic equipment used in building networks, including the switches, routers and servers used in wireline networks, as well as the antennas and base stations for wireless networks. The company also offers wavelength selective switches that are used to switch network traffic from one optical fiber to multiple other fibers without first converting to an electronic signal. Its optical components primarily consist of packaged lasers and photo detectors for data communication and telecommunication applications; and passive optical components for telecommunication applications. The company markets its optical products through its direct sales force, as well as through a network of distributors and manufacturers’ representatives to the manufacturers of storage systems, networking equipment, and telecommunication equipment in the United States and internationally. Finisar Corporation was founded in 1987 and is headquartered in Sunnyvale, California.
