780 830 850nm Fiber Circulator MCCIR-780
The 780 830 850nm three-port fiber circulator is a multiport nonreciprocal optical device that transmits light in only one direction. A signal entering port 1 exits port 2; a signal entering port 2 exits port 3, both with low loss. Light entering port 2 experiences high loss toward port 1. Likewise, light entering port 3 experiences high loss toward ports 1 and 2. Mingchuang Optoelectronics produces three-port and four-port fiber circulators with different power ratings and wavelengths. Applications include fiber lasers, add/drop multiplexers, bidirectional pumping systems, dispersion compensation devices, fiber sensing and scientific research.
