The RETN Group has launched a new backbone portion connecting Frankfurt, Paris and London. New DWDM network segment is built with the help of new generation Infinera ILS2. The scalable network solution is based on distributed Raman amplifiers and BMM2 cards and allows 1 600 Gbps upgrade as well as delivery of 100 Gbps lambdas. And it doesn’t require further upgrade of optical fibers and amplifiers. The total length of the RETN network has reached 14 000 kilometers.
