GracyFiber Optical Fiber WDM Filter is a high-performance thin-film wavelength management device designed for precise separation and combination of multiple optical bands over a single fiber. Supporting 1310 nm, 1550 nm, and C-band Red / Blue wavelengths, the filter operates across the 1260–1620 nm spectrum to enable efficient multi-service signal routing.
Based on an all-fiber optical structure, the device delivers ultra-low insertion loss, high isolation, and extremely low PDL, ensuring minimal impact on live traffic. With multiple packaging options—from miniature fiber tubes to 19″ rack-mounted modules—it is well suited for access, metro, and system-level optical integration.
