    Optical Fiber Circulators - Wideband (S+C+L Bands)

    Model CIR-3-CL/SCL
    Price:   US$289.00 US$249.00
    Available Options:
    Connector Type:

This optical circulator is specially designed for applications that require wide operation wavelength range. The C+L bands optical circulator works from 1520nm to 1625nm - over 100nm and covers the most useful DWDM bands - C band and L band. The S+C+L optical circulator covers three bands from 1470nm to 1610nm.
This product has low insertion loss over the whole wavelength range and can handle up to 1000mW optical power (optional).
It can be used in C and L band WDM optical communication networks, as well as optical sensoring systems that utilize ASE broadband light sources.
