Barnfind CWDM Mux/Demux is a passive technology, it allows for any protocol to be transported over the link, as long as it is at a specific wavelength (i.e. HD over fiber at 1570nm transported alongside 3Gbps SDI at 1590nm). This allows for long-term future proofing of the networking infrastructure because the multiplexers simply refract light at any network speed, regardless of the protocol being deployed.
Barnfind CWDM Mux/Demux can support up to 18 wavelengths between 1270nm to 1610nm in 20nm increments when com fiber is ITU-T G.694.2, however if com fiber is ITU-T G.652, we recommend adopt 1270nm and 1290nm instead of 1390nm and 1410nm because of water peak loss.
Barnfind provides a complete portfolio of CWDM Mux Demux and Optical Add Drop Multiplexer (OADM) units to suit all applications.
CWDM Mux/Demux is a flexible, low-cost solution that enables the expansion of existing fiber capacity.
The CWDM Mux/Demux lets operators make full use of available fiber bandwidth in local loop and enterprise architectures.
Barnfind CWDM Mux/Demux is a universal device capable of combining up to 18 optical signals into a fiber pair or single fiber. It is designed to support a broad range of architectures, ranging from scalable point-to-point links to two fiber-protected rings
