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
Paolo Bolletta // TSP18 // Athens, 2018/07/04 4
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
Paolo Bolletta // TSP18 // Athens, 2018/07/04 5
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
