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.
