FWDM Filters

FWDM Filters are compact, high-performance wavelength division multiplexing components designed to combine or separate specific wavelengths over a single optical fiber. Commonly used in FTTx, PON, and EDFA systems, these filters utilize thin-film coating technology to deliver low insertion loss, high isolation, and excellent wavelength stability. SunmaFiber offers a wide range of FWDM filters, including configurations such as Pass 1310nm & 1490nm / Reflect 1550nm, Pass 1550nm / Reflect 980nm, and more, to meet various application needs. All products support customization in fiber length, connector type, and package style for seamless system integration.
