1550nm high power fiber optic circulator is a three-port device, and light can only propagate in one direction. The signal input from port 1 is output from port 2 with low loss; due to its irreversible characteristics, it is often used in bifurcation multiplexers, bidirectional pumping systems and dispersion compensation devices or in combination with FBG systems to separate optical channels, and it can also be used for bidirectional transmission of signals in a single fiber application
High Power Polarization Maintaining Fiber Circulator 1550nm 20W
The 1550nm high-power fiber optic circulator is a three-port device, and light can only travel in one direction. The signal input from port 1 is output from port 2 with low loss; due to its irreversible characteristics, it is often used in bifurcation multiplexers, bidirectional pumping systems and dispersion compensation devices or in combination with FBG systems to separate optical channels, and it can also be used for bidirectional transmission of signals in a single fiber application. Qinghe Optoelectronics adopts a unique process and optical path design to enable it to withstand a power of 20W. Our solid technical foundation also accepts the development and customization of various special parameters.
