Is wavelength division multiplexing WDM the same as code division multiplexing CDM
The Wavelength Division Multiplexing (WDM) system encompasses two distinct wavelength patterns: Coarse Wave Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM). Multiplexing is a technique used in telecommunications and computer networks to combine multiple signals or data streams into a single transmission medium. The subsequent discussion will delve into a comprehensive introduction of. Frequency division multiplexing is defined as a type of multiplexing where the bandwidth of a single physical medium is divided into a number of smaller, independent frequency channels. These technologies will be further explored in detail.
