Multiplexing (WDM)

Introduction
  • Wavelength Division Multiplexing has been the
    preferred choice of technology for transmission
    of data in the form of light signals over a fiber
    cable. It helps in maximizing the capacity of
    fiber network and avoids excessive wiring.
  • This technology was initially used only by
    private carriers and service providers. But with
    consistent upgradation and technical
    improvements, WDM has been widely used by
    government organizations, data centers etc.

What is Wavelength Division Multiplexing?
  • WDM is a technique that multiplexes individual
    light wavelengths for transmitting data over a
    single medium. WDM components work opposite at
    the receiving end by de-muxing the combined light
    wavelength back into an individual and routed to
    their receivers.
  • To put it simply, the WDM system combines signals
    with multiplexing (MUX) and separates them using
    de-multiplexing (DEMUX).
  • This technology is mainly used in
    telecommunication applications.

4
Advantages of Wavelength Division Multiplexing
(WDM)
  • It has ultra-large data transmission capacity.
  • It easily connects new channels without
    disrupting the existing network traffic
  • All wavelengths are independent which ensure
    transmission transparency
  • WDM System offers reliability.
  • This technology maximizes fiber utilization and
    optimizes overall network investments.

5
Classification of WDM
  • Wavelength Division Multiplexing is divided into
    two categories
  • CWDM i.e. Coarse Wavelength Division
    Multiplexing This technology combines multiple
    signals at various wavelengths. CWDM is
    compatible with both GBIC and SFP Connections.
  • DWDM i.e. Dense Wavelength Division Multiplexing
    This technology is a vital form of fiber optic
    communications. It intensely increases the
    bandwidth of a single fiber cable. it is used in
    cloud data centers.

6
Components of WDM
  • There are 4 main components of Wavelength
    Division Multiplexing (WDM)
  • Transceivers
  • Mux and De-Mux
  • Patch Cable
  • Dark Fiber Network
