3 Ports Optical Circulator 1310/1550nm

What is  the advantage of Wavelength Division Multiplexing?

A WDM system can carry multiple formats of "service" signals, such as ATM, IP, etc.; in network expansion and development, it is an ideal means of expansion, and it is also the introduction of new broadband services (such as CATV, HDTV, and B-ISDN, etc.) Favorable means, adding an additional wavelength can introduce any desired new services or new capacity; using WDM technology to achieve network switching and recovery, which may realize a transparent and highly survivable optical network in the future; transmission in the national backbone network At the same time, the application of EDFA can reduce the number of SDH repeaters in long-distance trunk systems, thereby reducing costs.

Mechanical Fiber Optic Switch, WDM PD, Pigtail PD, TAP WDM Devices, Optical Isolator, Optical Circulator, etc., are the most commonly used WDM Related Equipment in construction of optical network.

Product Information:

3 Ports polarization-insensitive optical circulator, compact light wave component that routes incoming signals from Port 1 to Port 2, incoming Port 2 signals to Port 3 and incoming Port 3 signals to Port 4, while blocking the reflected light. The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.
