The wavelength division multiplexer series are designed and manufactured to Telcordial and ITU
standard. The devices use environmentally stable thin film filters and advanced packaging technology to
achieve wide pass band, low insertion loss, high channel isolation and excellent environmental stability.
They can be used individually to perform single channel add or drop function or can be cascaded into
sequence for multi-channel applications in CWDM/DWDM systems.
