Product Description
780nm 3-port Optical Circulator Three-port Optical Fiber Circulator
A 780-1080nm High Power Circulator is an optical device that directs light signals in a specific wavelength range (780-1080nm) through different ports with minimal loss. It features high return loss, low insertion loss, and is known for its stability and reliability. It's commonly used in test instruments, medical devices, and optical fiber amplifiers to manage light signals efficiently.
