Dense Wavelength Division Multiplexers (DWDM) utilize thin film coating technology and dedicated optical design to achieve upstream and downstream light within ITU wavelengths. It provides the characteristics of ITU channel center wavelength, low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and glue-free loop. In telecommunications network systems, it can be used for upstream or downstream optical signals.
