Customizable Wavelength TGG Based 3-Port Polarization Maintaining Optical Circulator for Fiber Amplifier
The key functionality of a fiber optical circulator is directing light sequentially from port to port with low loss in only one direction, which results in the separation of signals traveling along an optical fiber in opposite directions.
Gezhi Photonics manufactures various in-line fiber optical circulators, including high-power optical circulators, single-mode & multimode fiber circulators (polarization-independent & polarization-maintaining fiber optical circulators). These fiber circulators are customizable upon request.

1. Above specifications are for device without connector. If with connector, IL will be 0.3dB higher, return loss will be reduced by 5dB and Extinction Ratio will reduce 2dB.
2. If there is pulse application, please be sure to inform us of pulse energy and peak power.
