Compact Dense Wavelength Division Multiplexers (CDWDM) allow customers to expand the bandwidth capacity of their next-generation networks. Based on thin film filter technology, the device is less than one-third the size of traditional cascaded DWDMs of similar channel count. Our CDWDMs feature low insertion and polarization dependent loss with excellent temperature stability. Available in a variety of ITU channel configurations (20-, 16-, 8-, 4-) with a 100 GHz channel spacing, the devices are ideal for those applications requiring small size and high optical performance.
