The CWDM Mux / Demux module is based on dielectric thin-film technology designed for integration in low cost Metro and Access networks. These include applications such as fiber to the home, business or curb. The module enables 4 or 8 channels to be either combined (added) or separated (dropped). The filters operate with a channel spacing of 20nm corresponding to standard CWDM wavelengths. Santec's CWDM module has low insertion loss, high channel isolation, flat passband. Additional filters, to enable cascading of devices, or addition of 1310nm or other wavelength, can also be included in the module.
