FAH0347 Series Rev.1: [Apr.2004]
4 or 8 Channel CWDM Mux/DeMux Data Sheet
Preliminary FAH0347,FAH0348
FAH0347 : 4Channel Type
FAH0348 : 8Channel Type
Overview
The CWDM Mux/DeMux Filter utilizes dielectric thin film technologies and is designed for use in low cost Metro and Access networks, and CATV networks applications. The modules allow either four or eight channels to be combined (added) or separated (dropped). The thin film filters are designed for 20 nm
spacing and correspond to the standard ITU-T G.694.2 CWDM wavelength grid.
