Optical Isolator (LISO)
Optical Isolator
Lightem’s Optical Isolator, utilizing Faraday effect of Magneto optical crystal, is a passive
component which guides optical light in one direction and resists the optical light in the
backward direction. The unique manufacturing process and the epoxy-free optical path design enhance the device’s high power applications. With high performance, high reliability and low cost , it has been widely used in EDFA, Raman amplifiers, LFWDM systems, fiber lasers, transmitters and other fiber optic communication equipment.
