GARR-X: since 2011


Huawei OptiX OSN 8800 (6800 on OLA)

Key properties:• DCM compensated• 80 channels @50GHz spacing• λs: 10G and 40G IM-DD OOK• Max capacity: 3.2 Tbps• Client: 1G, 10G • ROADM:

• core nodes: colorless & directionless• colored & directionless

• WSON control plane: preset restoration• MUX and WSS: equipped with VOA• Integrated OSA Board in each node• OTN Matrix: 1.28Tbps

GARR-X Progress: since 2015


Infinera DTN-X Intelligent transport network Key properties:• 16 superchannels@500G Fixed Grid• Max capacity: 8 Tbps

• Client: 10G, 40G, 100G• SD-FEC (reach up to ULH)• For each superchannel: 10 coherent carriers

spacied at 200GHz on a 25GHz Grid• PM-QPSK, PM-BPSK

• NO WSS• OTN Matrix: 5Tbps or 2Tbps• GMPLS control plane• Restoration and protection available

Network Harmonization


why:• Increase P2P capacity • Make 100GE client services

available in the northern network • the Infinera node needed only

where the 100GE service ends• Extend the lifetime of the

Huawei technology• All terminal nodes are kept to

deliver the native 10 Gbpsservices. Amps serve both platforms

Goal: To measure performances/pe-nalties of the Infinerasuperchannelalongside native lambdas over Huawei line system

Idea:• Share of the optical spectrum

among Huawei and Infinerasignals

How: Field trial on production network
