Special Wavelength Coupler

 

The Special Wavelength Coupler is a passive optical component specifically designed for combining or splitting optical signals at non-standard wavelengths, such as 980 nm, 1480 nm, and 1590 nm. Unlike traditional WDMs limited to 1310/1550 nm, these couplers utilize custom single-mode fiber and are optimized for wavelength-specific performance in specialized optical systems.

Tailored to meet customer-defined coupling ratios and optical requirements, each unit is built with precision thin-film technology and undergoes rigorous quality control. The product is compliant with Telcordia GR-1221-CORE standards and meets RoHS environmental regulations.
