1x2 Fused Type PM Coupler , FC/APC , 980nm, 1064nm, 1310nm, 1550nm
Based on Takfly's fused fiber technology, the PM coupler demonstrates very low loss, high power handling and there is no price penalty for adding a second input port. The center operating wavelength may be chosen from within a wide variety of operating passbands, including 780, 820, 980,
1064, 1310, 14xx, 15xx and 16xx nm.
In common with all PM components, it is necessary to launch into either the slow or the fast axis to maintain polarisation. For the G&H PM coupler,
specifications are based on slow axis launch,although fast axis versions are also available if requested.
