DWDM Module, Dense Wavelength Division Multiplexer Modules

Product Details

GLSUN DWDM (Dense Wavelength Division Multiplexing) Modules are optical devices that combine and separate multiple optical signals, each on its unique wavelength, over a single fiber. DWDM is designed for long-distance, high-capacity networks, offering significantly higher channel density than CWDM (Coarse Wavelength Division Multiplexing). DWDM technology is commonly used in telecommunications backbones, data center interconnects, and long-haul networks, where maximizing fiber capacity and supporting high-bandwidth applications are critical.

Features
·Low insertion Loss
·Low PDL
·High channel isolation
·Excellent environmental reliability

Applications
·WDM system
·CATV
·MAN(Metropolitan Area Network)
