Construction, background and applications of optical nonreciprocal devices are discussed. Operation of optical isolators and circulators based on Faraday polarization rotation is analyzed. Applications of the nonreciprocal devices for multipass amplifiers are presented. Construction of polarization independent circulators is discussed including an all fiber circulator and application of the circulators for fiberoptics communications is included.
