16/8/4/2CH DWDM Mux Demux https://www.wdmlight.com/16-8-4-2CH-DWDM-Mux-Demux.html The DWDM multiplexer/demultiplexer is designed for multi-wavelength DWDM network applications. It works on an ITU grid with 100 GHz channel spacing based on thin-film filter (TFF) technology. The wavelength range of DWDM is from 1525nm to 1565 nm with an optional ITU channel wavelength. It has a series of advantages, such as multi-kind of packaging structures, low insertion loss, high channel isolation, and so on. 18CH DWDM Mux Demux Features Low insertion loss (IL) High channel isolation High stability and reliability Wide operating wavelength range Provide 1 to 32 channels with a compact design Conform to ITU-T G.694.1 Conform to Telcordia GR-1209-CORE-2001 standard Conform to Telcordia GR-1221-CORE-1999 standard Conform to RoHS-6 (no lead) DWDM Mux Demux Specification Channel number 1 2 4 8 16 Operating wavelength (nm) 1525~1565 Center wavelength (nm) ITU-T Grid Channel spacing (nm) 0.8nm(100GHz) Channel insertion loss (dB) ≤0.8 ≤1.2 ≤1.8 ≤2.6 ≤4.5 Channel bandwidth (dB) ITU±0.11 Flatness (dB) ≤0.5 Adjacent channel isolation (dB) ≥30 Non-adjacent channel isolation (dB) ≥40 Return loss (dB) ≥50 Directivity (dB) ≥55 Polarization-dependent loss (dB) ≤0.2 Polarization mode dispersion (ps) ≤0.2 Power Handling (dB) ≤500 Operating Temperature (°C) 0~+70 Storage Temperature (°C) -40 ~+85 Package type Steel tube, ABS box, LGX standard box, 1U standard 19-inch rack

The NYCMD series utilizes Coarse Wavelength Division Multiplexing (CWDM) technology. This approach assigns specific wavelengths within the 1270nm to 1610nm range to different data channels, maximizing fiber optic bandwidth utilization while minimizing crosstalk. https://www.neoncq.com/nycmd-series-dfb-cwdm-microwave-powerful-laser-diode
