DWDM devices demonstrate low-loss temperature insensitivity and reliable performance. Compact modules are also available with low insertion loss, low crosstalk, and wide passband with high isolation, which enables users to establish a low-cost bi-directional optical. DK Photonics Athermal AWG DWDM (Arrayed Wave-guide Grating Dense Wavelength Division Mux/Demultiplexer) Modules are part of a series of high-performance products based on silica-on-silicon planar technology and a unique athermal packaging design requiring no electrical power, software or. Fiberdyne Labs offers Dense Wavelength Division Multiplexer (DWDM) Modules in a wide variety of formats. While Fiberdyne offers some models as "standard," we will also produce customized DWDM modules. Customization can include the number and selection of DWDM channels. Additionally, modules may.
