3 Port Multi-mode Optical Circulator 830 835 850nm
Description
The 3 port 850 nm Multi-mode Optical Fiber Circulator is a fiber optic componet built with multi-mode fiber. It allows light to be transmitted in only one direction while blocking the opposite transmission, it's light path is port 1 to port 2, and port 2 to port 3. The optical circulator could be built by 50/125μm or 62.5/125μm multimode fiber.
