PM Couplers/WDMs
Quick Overview
olarization-maintaining (PM) fiber couplers in coupling ratios from 1% to 50%, manufactured using industry-standard polarization-maintaining fiber. Available in slow axis, fast axis, and axis-independent variants.
Based on our highly developed fused fiber technology, our PM fiber couplers demonstrate 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.
Our PM fiber couplers operate over a -55°C to +85°C temperature window, making them suitable for applications in harsh environments.
