WDM Service

Transfer of data at high capacity with a minimal delay

WDM connections are implemented using the extensive Elisa WDM backbone network. The service is well suited for connections requiring high capacity, such as intercity backbone or data center connections.


Optical wavelength technology enables implementing the connection with minimum delays and delay fluctuations.


The Elisa WDM service is also available internationally. Please ask for our offer.
