This 16-channel, 200 GHz O-Band PM DWDM Module is a polarization-maintaining (PM) Dense Wavelength Division Multiplexing/Demultiplexing module designed for operation within the O-band. It covers the 1260–1380 nm wavelength range and utilizes a 200 GHz channel spacing to enable high-density transmission across 16 distinct wavelength channels. According to product specifications, the module primarily covers a channel range spanning approximately 1295.56 nm to 1312.58 nm, with a passband precisely controlled within ±0.2 nm of the center wavelength; this makes it ideally suited for carrying Gigabit and higher-speed data services.
