HJY’s Wavelength Division Multiplexer (WDM) is based on AWG technology. This proven technology offers wide channel bandwidth, flexible channel configuration, low insertion loss, and high isolation. This DWDM series modules are passive optical multiplexer/demultiplexer designed for metro access applications that represent the state of the art in fiber optics design. This Mux/Demux module multiplexes and demultiplexes multiple DWDM wavelengths of 100GHz channel spacing into a ring or point-to-point network, ideal for telecommunications and networking.
HJY’s Dense Wavelength Division Mux/Demultiplexer Athermal Arrayed Waveguide Grating(AAWG) 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 temperature control for a completely passive DWDM solution. This product range offers a combination of very low loss and high channel isolation along with long term reliability .Each module can perform Mux and Demux functions. Both C- and L-band devices are available with flat top spectral response. Custom frequency grids, fiber types and connector options are also available
