• Lambda point to point unprotected link at a fixed bit rate of 2.5 and 10 Gb per second;
• Lambda Ring configurable ring of unprotected lambda segments between two or more terminal points in the Eutelia network.

Service is delivered at the Eutelia PoP (PoP-to-PoP option) or at customer site (End-To-End option).

Price determinants are the required transmission capacity, contract duration and offer type, mainly whether the optical fibre local loop is included or not.
