Product Details

Product Overview of PM Filter Coupler

Low Insertion Loss 1x2 or 2x2 Polarization Maintaining Filter Coupler

1x2 or 2x2 Polarization Maintaining Filter Coupler

GEZHI Photonics uses unique fusing technique and polarization maintaining fiber to build the polarization maintaining filter coupler (PMC).The 1310,1480,1550,1940,2000nm Polarization Maintaining (PM) filter coupler / splitter is a compact low loss micro-optic filter type inline coupler (1x2 or 2x2) which provides PM optical signal splitting (various splitting ratios available) over a wide bandwidth.

Note: 1. Customization is available. The connector default slow axis alignment key

2. Above specifications are for device without connector, If with connector, IL will be 0.3dB higher, return loss with be reduce 5dB and Extinction Ratio will reduce 2dB.

3. For >10W high power applications, we will use heat sink package

4. If there is pulse application, please be sure to inform us of pulse energy and peak power.
