Axpo WZ-Systems offers its customers the use of the most modern DWDM systems (Dense Wavelength Division Multiplexing) for the simultaneous transmission of multiple broadband communication links over a single lightwave link. The transmission capacity can be increased almost indefinitely with the DWDM method. On the one hand, this method can be used to cover greater distances, and on the other hand, the data rates of signal and message transmission are individual and cost-optimized. Up to 80 wavelengths with a bandwidth of 100 Gbit/s can currently be transmitted on our modern infrastructure.

Individual connections with high performance

Axpo WZ-Systems' DWDM services are part of a crisis-proof data network. Our services are primarily aimed at security authorities and organisations as well as private and public companies with an increased need for security, flexibility and performance. Dedicated connections (redundant routing along the entire route) with the options Equipment Protection, Path Protection or Equipment and Path Protection enable us to guarantee very high availability. In addition, the optical latency times of the system are both calculated and measured. Our infrastructure is state-of-the-art and is regularly maintained and updated. We provide our customers with a wide range of services, protocols and interfaces.

Your benefits

  1. High-quality transmission capacities over great distances
  2. High availability due to redundancies in the backbone and comprehensive network monitoring
  3. Low latency periods
  4. Short switchover times during malfunctions

Wavelength division multiplexing

Multiplex methods are methods for signal and message transmission in which several signals are combined and transmitted simultaneously. Wavelength Division Multiplexing (WDM) is an optical frequency division multiplexing method used to transmit data over fibre-optic cables. In the so-called Dense Wavelength Division Multiplexing (DWDM) method, the wavelengths (spectral colors) used for transmission in the fibre-optic cable are particularly close to each other. This method is most frequently used to combine signals from the third optical window (1,550 nm) and transmit them over long distances.
