Our CWDM products separate wavelength into bands of 20 nanometers to cover the complete fiber optical communication spectrum from 1270 nm to 1610 nm. A CWDM SFP module is an optical transceiver that uses Coarse Wavelength Division Multiplexing (CWDM) technology to transmit multiple data channels over a single strand of single-mode fiber, helping networks expand capacity without deploying additional fiber. CWDM and LWDM Components Wavelength and Polarization Test O-Band WDM Increased demand for fiberoptic transmission bandwidth over distances that do not require optical amplification repeaters, such as within and among data centers or within about 10 km, are driving the use of wavelength domain.
