Description of 3CH CWDM
3CH CWDM Mux Module ABS Box with customized wavelength and connector
CWDM DEMUX Module ABS box 1470-1610nm with SC/APC Connector 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 or 16 channels to be either combined or separated.CWDM module has low insertion loss, high channel isolation, and flat passband. Additional filters, to enable cascading of devices, or addition of 1310nm or other wavelength, can also be included in the module.
