Conventional DWDM SuperWDM

The backbone covers the main cities of France with total distance of 3311km, including 39 stations. Supporting built-in OSA and ALC function reduce OPEX dramatically. Compared to other solutions, SuperWDM realizes 35% - 50% network cost saving.


Total network distance is 5000km while SuperWDM span is about 1300km.

Existing fibers are with high loss, which challenge to transparent transport.

SuperWDM enhance system’s span loss budget and reduces REG.
