Product Overview of PM Fused Coupler
High Quality 1x3 Polarization Maintaining PM Coupler for Fiber
Optical Instrument
1x3 Polarization Maintaining Fused Coupler
GEZHI Photonics uses unique fusing technique and polarization
maintaining fiber to build the polarization maintaining fused
coupler (PMC).The coupling ratio also could be selected. It
features low excess loss, small size and high polarization
extinction ratio.It is widely used for optical sensors, optical
gyro and fiber optical instrument. |

Note: 1. the PM fused coupler is both axis working, no axis can be
blocked; default test extinction ratio is on the slow axis.
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.
