Open Photonics DWDM Systems Deployment Within the CESNET2 Network, With Emphasis to Single Fibre Bidirectional Operation
This paper describes an experience with the deployment of DWDM system, based on open photonic devices family called CzechLight, within the CESNET2 network optical infrastructure in 2008. Emphasis is given to single fibre bidirectional DWDM systems. The key motivation for CL DWDM based systems deployment is a cost effective solution for gigabit (1-10Gbps) connectivity provisioning for small PoPs with the backup connectivity based on pure optical circuits. A NIL approach, i.e. optical line design without the inline components (e.g. amplifiers and chromatic dispersion compensators), was implemented.
