850nm Fused PM fiber Coupler-PMF-850


PM fiber coupler works at 850nm, and its working bandwidth is +/-15nm and its E.R

Description

Details

Rayscience uses its unique fusing technique and polarization maintaining fiber to build the polarization maintaining fiber coupler (PMC). The coupling ratio could be selected according to customer's request. It features low excess loss, small size and high polarization extinction ratio. PMC is widely used for optical sensors etc.
