50:50 Single Mode 1×2 155nm Polarization Maintaining Filter Coupler
Basic Information:
Polarization maintaining couplers (PMC) combine or split the
incoming light and maintain their polarization states at the output
ports.
Two types of PM couplers are available, micro-optical
sub-components based or PM fused fiber-based. The PM couplers have
central wavelengths at 1310nm, 1550nm, or 1064nm. Their coupling
ratios can be specified with high accuracy. Two configurations, 1x2
or 2x2, are available.
