Single Mode WDM

 

The Single Mode 980/1550 Wavelength Division Multiplexer (WDM) is a passive optical component designed to combine or separate optical signals of 980 nm and 1550 nm wavelengths within a single optical fiber. It enables efficient wavelength multiplexing and demultiplexing in Erbium-Doped Fiber Amplifiers (EDFAs), fiber laser systems, and WDM communication networks.

Utilizing advanced thin-film filter technology and precise manufacturing techniques, this WDM offers low insertion loss, high isolation, and minimal polarization-dependent loss (PDL), making it ideal for high-performance applications in dense wavelength routing environments. Its compact structure and robust packaging ensure stability across a wide temperature range, making it suitable for both lab and field deployments.
