– SDM1 fully qualified in 2019

ASN proposes an innovative design approach optimizing cost per bit. This disruptive solution is an alternative to the traditional design philosophy status quo.

The SDM1 powered by ASN is revolutionizing the traditional submarine network design: “High power, High OSNR, High Effective Area (Aeff) fibre” by using “Low Power, Low OSNR, Low Aeff Fibre and more fibre pairs” in order to:

Push the limits of theoretical design capacity by minimizing nonlinear effects that add complexity and cost;
Create and efficient optical and electrical network based on repeater pump farming, low Aeff submarine fibres, and higher fibre counts;
Work in the optimum spectral efficiency of SLTE : 2-3 b/s/Hz and lower chromatic dispersion compensation.

SDM1 powered by ASN is a simple and smart combination of:

New product features, including :
– Repeater pumping schemes;
– Higher Fibre count submarine cable designs.

Proven and widely use fibre technologies;
Optimised electrical dimensioning resulting in a smaller cable conductor;
Optimum spectral efficiency range (2-3 b/s/Hz) with lower chromatic dispersion compensation.
