Produts Details

Product Name: Dense Wavelength Division Multiplexer (DWDM Series ), Filter Component


The Dense Wavelength Division Multiplexer series is designed and manufactured to Telcordia standard and ITU standard. The devices use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used individualy to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in DWDM systems.
