Dense Wavelength Division Multiplexer, 100GHz/200GHz DWDM

The high precision optical filter provides the dense wavelength division multiplexer with accurate central wavelengths, and high channel isolation. It adopts a collimator conforming to ANSI, TIA, ISO, and IEC standards in terms of durability, moisture resistance, coupling stress, and optical fiber tensile strength. This provides the DWDM with reliable performance.

Dense Wavelength Division Multiplexer, 100GHz/200GHz DWDM

Principles and Applications
Based on a special property of fiber-optics, DWDM terminal multiplexer can combine a group of signals onto a single optical fiber. Dense wavelength division multiplexing is an effective laser technology to increase bandwidth over existing fiber optic backbones. It maximizes the use of available optical fiber cable.


Our dense wavelength division multiplexers are effective solutions for long distance signal transmission, while eliminating the demand for installing more fiber cables or increasing system bitrate. They have been widely used in Gigabit and 10G Ethernet, SDH/SONET, ATM, ESCON, FTTx, and CATV systems.
