780~890nm(0.3~10W)-3-Port (High/Low)-Power Polarization-Maintaining Circulator
The fiber circulator is a key passive optical communication device whose value comes from precise magneto-optic control. Faraday rotation establishes unidirectional optical transmission paths for efficient separation and directed routing of signals in different directions. This nonreciprocity is indispensable in modern optical networks, particularly single-fiber bidirectional communication, and enables recovery and reuse of backward light unavailable to conventional isolators. Note: Wuhan Guanghong Technology Co., Ltd. customizes circulators in various specifications.
