Import Cwdm — Buy in Bulk from Supplier in China

The Cwdm is a coarse wavelength division multiplexer designed for optical signal routing in fiber-optic networks. It combines or separates multiple optical channels at specific wavelengths, typically spaced at 20nm intervals, to increase bandwidth over single-mode fiber. The device operates within the C-band (1530nm to 1565nm) and is built for low-loss signal transmission in telecom and CATV systems.

It uses fused fiber technology with precision alignment of dielectric filters to achieve low insertion loss and high channel isolation. The housing is typically metal or ceramic to ensure thermal stability, and the connectors are standard SC/APC or LC/APC. Performance parameters such as polarization dependent loss (PDL) and return loss are engineered to meet industry benchmarks for passive optical components.

This component is purchased by network equipment manufacturers, fiber-to-the-home providers, and test lab integrators deploying dense optical infrastructure. It is commonly used in access networks, metro rings, and CATV distribution systems. Buyers should confirm the exact wavelength channels, number of ports, and connector types required, as customization is common and lead times vary based on configuration.

Sichuan Guangfa Technology Co., Ltd is located in Mianyang, Sichuan Province, China, within the High Tech Zone. The company is classified as a harbor-tier supplier and an imported-tier entity, indicating compliance with export documentation standards.
