  1. Commercial Deployment of 100G Ultra-Long-Haul Optical System in Verizon's Core European Network Marcel Rijnders Director EMEA Managed Services September 20, 2010

  2. Verizon European Backbone Growth Requirements • Capable to support hybrid capacity growth • Mix of 10Gb/s, 40Gb/s and 100Gb/s • High performance and low latency • Avoid the use of DCMs • Compatible with existing photonic layer infrastructure • Expanding system lifetime • Maintain existing line amplifiers, mux/demux devices and wavelength selective switches • Toleration to typical physical plant uncertainties • Mix of various fibre types, connectors, splices, re-routes, etc. • Service interruption free capacity upgrades • Avoid major network disruptions and/or high risk maintenance • Easy reconfiguration with minimal physical labour • Employ standard Field Operations staff • Limit logistics and truck loads

  3. WSS ROADM Line Amplifier Glass-Thru site CPL Raman Link Verizon European Backbone100Gb/s Production Deployment • Network Section Paris – Frankfurt • Ciena DWDM CPL & OME6500, 88 channel DCM-less • 890 km optical distance • Utilisation >30 x 10 Gb/s wavelengths • 13 x amplified spans • 5 x Raman (loss > 23dB) • 6 x ROADM with 50 GHz WSS Paris 890 km Frankfurt

  4. f-Df f+Df Verizon European Backbone100Gb/s CoFDM Modem Transmitter • Based on commercially deployed 40Gb/s technology • Data rate 115Gb/s (2 x 14.4 GBaud DP-QPSK) • Optical subcarrier spacing 20GHz Receiver • Optical mixing & electrical LP filtering • Coherent DSP processing +/- 50,000 ps/nm ~25 ps mean DGD • Proprietary hard FEC (7% OH, 9.2dB coding gain) BER = 3.8E-03 corrected to < 1E-15

  5. Verizon European BackbonePre-Deployment Testing • Lab spectrum identical to field >30 de-correlated 10Gb/s signals • OSNR margin > 6dB

  6. Verizon European BackboneProduction Deployment • Operational since December 2009 • No system failures reported • Pre-FEC BER < 1E-04 (FEC limit = 3.8 E-03) • Client access 10 x 10GE carrying real time traffic

  7. Verizon European BackboneSummary • Operational and error free 100Gb/s production system • Minimal field staff training required • No more than standard care is needed • Simple (10Gb/s) engineering rules • No modifications needed in the optical plane • Very straightforward deployment • Installation of equipment only at terminal sites • Highly automated commissioning due to modem training NEXT • Further expansion of 100Gb/s channels in Verizon’s backbone • Enhanced scalability of the Ultra-Long-Haul network • All routes confirmed for scaling to 100Gb/s • Deployment of 100GbE client interfaces • Standard is now defined: IEEE 802.3ba • Router suppliers ready to deliver Ethernet PICs • Deployments of 10x10Gb/s Multi-Rate client interfaces • 10GE, STM64, OTU-2 • Migration of existing lower rate interfaces onto 100Gb/s channels
