Product Description
The CWDM Mux/Demux Module leverages thin-film filter technology to enhance the capacity of existing fiber infrastructure by enabling multiple channels (wavelengths) over the same fiber cabling. Each channel operates independently, allowing for the transport of different data rates and protocols. This flexibility makes CWDM an effective solution for addressing fiber shortages and achieving transparent transmission of diverse services, ultimately reducing network build costs. Featuring low power consumption and a compact design, these modules are widely used in metro aggregation and access layers for short-distance transmission.
SUNET’s CWDM Mux/Demux products support up to 16 or even 18 channels on a single fiber. They are available in various package types, including ABS box, LGX package, and 19″ 1U rack-mount.
