Fiber Optical Passive Components

GEZHI Photonics provides 1x1, 1x2, 2x2 Bypass, 2x2 Full, Dual 1x2, Dual 2x2 Bypass, Dual 2x2 Full, 1x4, 1x8 Optical Switches

  1. PM Fiber Product

    Polarization maintaining components, PM, are widely used accross many industry applications, including Fiber Amplifiers, Fiber Lasers, high speed communication systems and Optical Test / instrumentation.

  2. High Power Optical Products

    GEZHI Photonics’ high power components rang from 780nm to 1550nm, handling power from 300mW to 50W or other on request. Low insertion loss, high isolation, high power handling, high return loss, high extinction ratio and excellent environmental stability and reliability. It is ideal for High Power Fiber Amplifier, Fiber Laser, and Instrumentation applications.


    WDM is protocol and bit-rate independent. These networks can transmit data in IP, ATM, SONET/SDH, and Ethernet.
    They can handle bit rates between 100 Mb/s and 40 Gb/s. Therefore, WDM type networks can carry different types of traffic at different speeds over an optical channel.

    GEZHI Photonics production lines have now been increased to cover the full product range of WDM devices, module, and module integration, including thin-film filter (TFF) base WDM products, and also fused fiber base coupler WDM products.

  4. Optical Switches

    Optical switches are widely used in optical add/drop applications that need to be reconfigurable.
    They are also used for network switching applications for fault protection.
    GEZHI Photonics opto-mechanical switches offer industry-leading performance with Telcordia compliant reliability.
    The Optical switch variants include:1×1, 1 x 2, 2 x 2 Bypass, 2×2 Full, Dual 2×2 Bypass, 1×3,  1 x 4, 1 x 8, latching or non-latching options.

  5. Optical Circulator

    Optical circulators are used to build WDM / OADM, bi-directional transport systems, dynamic gain equalizers (DGE) and dispersion compensation modules (DCM). Optical Fiber Amplifiers, Fiber Lasers, Fiber Dispersion Compensation & OTDR.
    GEZHI Photonic has a wide range of Optical circulators which can cover many applications. Our Circulators are fully tested and will provide excellent performance and stability within your system.

  6. Optical Isolators

    An optical isolator allows the transmission of light in only one direction. i.e. this optical component will prevent unwanted light from returning back into an optical cavity. To relate to its function in Electrical terms, would be a similar to that of a diode, allowing current to only flow in only one direction. The main component of optical isolators is usually a Faraday rotator.
