RENATER Optical transport network2019 updates

Sept 2019

CEF meeting, CESNET, Prague

Agenda

• Maps and general key figures

• Optical engineering updates

• Dark Fiber/Links part

• Transmission equipment part

• Time/Frequency part

• Discussion : NREN optical skills… what for ?

• RENATER optical transport network is built mostly on dark fiber links.

• With roughly 13000 km, RENATER is one of the NREN with the largest footprint (referto Compendium 2017),

• Pairs of Dark Fiber are procured for a 10 to 13 years range time period with some of the major fiber operators in France/World (SFR, Celeste, Zayo…)

• This network is then divided into two parts :

• A main part (~80 %), so called backbone, which aims at interconnecting the main POPs (major Cities/Universities in France) throughout France territory,

• A second part, so called Metropolitan networks, split in several smaller networks covering big cities (Paris, Paris-Saclay,…) or regions (Britany, Southeastern (PACA) region…) with an heteregenous technologicalenvironnement (equipment type, level of responsabilities,…)

• On the backbone part, RENATER is mainly using INFINERA equipment (ex CORIANT brand) to transmit, to amplify and to receive information.

• This equipment roll out started in 2015 for a 5-8 years time period,

• It is progressively replacing old generation non coherent CIENA equipment.

• Project covered ~80% of links :• 3-4 technicians/engineer involved,

• Started in feb 2017 and still ongoing,

• Main outcomes :• 14% were procured with a new operator,

• Despite this low level of challenger, cost dropped to a better price (around 0,12 €/m/an) because of volume, negociation and longer time range (13 years),

• Main difficulties :• Offers not always realistic leading to roll out

problems :• Several optical budgets were theoritical and came up as

unsatisfied on field,

• Lead time longer due to congestion paths or unpreparedadministrative procedures,

• Poor quality of deliverables leading to re-works,

Equipment renewal status progress

2015

•Contract awarded to CORIANT

•High level design definition (racks design, DCN definition,…)

•Beginning of equipment deployment : Interoperability POC, Pilote project

2016•First mass deployment in North and East regions

2017•Alien lambda over CIENA to speed up capacity delivering thoughout

France territory

2018•First introduction of high density cards : matrix (MFAB2), line cards

(OSM4C/4xOTU4) in order to uncongestion some big nodes

2019

•First introduction of 16QAM modulation line rate card(OSM4F/2x100/150/200 ports) and introduction of HD client interface card (OSM5C/5x 100 GE)

•Packet service introduction on mTera (still not concluding)

•First 100 GE end users

•INFINERA buys out CORIANT

2020

•Evolutions /upgrade projects in North and East regions (first regionsdeployed) ?

•Toward a packet service mode generalization (or not !)
