Terbium Gallium Garnet Based 1030nm Polarization Independent Optical Circulator

Product Specifications/Features
    The fiber optic circulator is a compact, high performance lightwave component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3.So fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port. They perform a similar function as an isolator, protecting the input fiber from return power, but also allowing the rejected light to be employed.

    Our 1030nm Polarization Insensitive Optical Circulator provides low insertion loss, broad band high isolation, excellent temperature stability and optical path epoxy free. It can be used for wavelength add/drop, dispersion compensation, fiber laser and EDFA applications.

    DK Photonics offers a large selection of polarization insensitive or polarization maintaining 3-port/4-port optical circulator. These devices can handle powers rang from 300mW to 20W, and have center operating wavelengths ranging from 850 nm to 1650nm.
    If you do not see a standard Optical Circulator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom circulator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.
