| High Light | 33/33/33 coupling ratio PM Fiber Splitter ，High Polarization Extinction Ratio Polarization Maintaining Fiber Coupler ，Multiple Wavelength Options 3x3 PM Fused Fiber Coupler | ||
Our 3x3 PM fused coupler is a polarization maintaining optical fiber splitter manufactured by Gezhi Photonics via advanced fused biconical taper technology. This 3×3 PM fiber coupler evenly splits input light into three equal 33/33/33% output ports, fully supporting both fast and slow polarization axes without axis shielding. Available in multiple common laser & communication wavelengths, the device features ultra-low insertion loss, high return loss and excellent polarization extinction ratio, widely deployed in coherent optical communication, power monitoring systems and precision fiber optic test instruments.

Important Notes
The PM fused coupler supports both polarization axes and cannot block any axis; standard extinction ratio test is performed on slow axis.
The above specs apply to bare devices without fiber connectors. If equipped with connectors: Insertion Loss rises 0.3dB, Return Loss drops 5dB, Extinction Ratio reduces 2dB.
For high-power scenarios over 10W, heat sink packaging is available upon request.
If used for pulsed laser applications, please provide pulse energy and peak power for customized design.
Standard 3x3 PM coupler housing with 6 fiber ports: Port1, Port2, Port3 as input group; Port4, Port5, Port6 as output group. Serial number printed on each metal package for traceability.
