Description

A CWDM (Coarse Wavelength Division Multiplexer) is a passive wavelength division multiplexing device used in optical fiber communication networks. It can combine multiple optical signals of different wavelengths into a single optical fiber for transmission, or separate signals of different wavelengths at the receiving end. This product supports a wavelength range of 1270nm to 1610nm, with a channel spacing of 20nm, and can achieve up to 18 channels of transmission, making it suitable for low-cost, high-capacity optical fiber link expansion. Utilizing thin-film filtering technology and micro-optical packaging design, the product features low insertion loss, high channel isolation, wide passband, low temperature sensitivity, and stable reliability, meeting the multi-wavelength transmission requirements of metropolitan area networks, access networks, data centers, and optical transmission systems.
