Scurtă descriere

The CL-ROADM multiplexer is a 40-channel reconfigurable optical add drop multiplexer (ROADM). Any combination of channels on a 40-channel grid can be dropped or added. The CL-ROADM allows for remote configuration and reconfiguration.

Multiplexor reconfigurabil - CL-ROADM


A reconfigurable optical add-drop multiplexer (ROADM) is a form of optical add-drop multiplexer that adds the ability to remotely switch traffic from a DWDM system at the wavelength layer. This allows individual wavelengths carrying data channels to be added and dropped from a transport fiber without the need to convert the signals on all of the DWDM channels to electronic signals and back again to optical signals. The main advantages of the ROADM are:

  • The planning of entire bandwidth assignment need not be carried out during initial deployment of a system. The configuration can be done as and when required. 
  • In ROADM, as it is not clear beforehand where a signal can be potentially routed, there is a necessity of power balancing of these signals. ROADMs allow for automatic power balancing and optical level measuring for each channel. 
  •  ROADM functionality originally appeared in long-haul DWDM equipment, but by 2005, it began to appear in metro optical systems because of the need to build out major metropolitan networks in order to deal with the traffic driven by the increasing demand for packet-based services.
