  29. 40 Gb/s Field Overlay • 40 Gb/s Error Free over 1200+ km in the field over existing commercially-available line-amplified systems • Extra gain margin at 1200 km • Simulations matched field performance Simultaneous 40G and 10G transmission on the same fiber

  30. General 40G Economic Information & Throughput Performance vs. 10 Gb/s

  31. Factors Affecting the Cost/DS3_Mile • Bit Rate • 40G systems have generally lower Cost/DS3_Mile than 10G: • 40G systems carry 4 times as much traffic as 10G systems, for only three times increase in the transponders and regenerators cost. • The other components of the system (e.g. amplifiers and WDMs) are independent of the bit rate. • Regenerator Reach • Longer reach results in a lower Cost/DS3_Mile. However the limitation is the allowed bit rate and number of WLs. • Number of Wavelengths and Bands • Increasing the number of WLs in the same band lowers the Cost/DS3_Mile, but if a new band is added, the increase in the amplifier cost may cancel out the advantage of the additional WLs. (Internal Study)

  32. Maximum Link Utilization for P(Hurst) = 10-3 Queueing Delay 40G extrapolation results: Max imum link utilization with TCP traffic giving a max 1 mS queuing delay at node: • OC-192: 94% - 97% depending on traffic characteristics (H value) • OC-768: 98%

  33. Summary

  34. Summary • Business drivers today are savings and revenue vs. rapid growth • Capital will be business case driven • Any New technology must have very low cost of entry to be adopted • Open systems and multi-vendor interoperability is critical • Emerging optical services are still in development • Most new revenue will derive from the services converged on the packet layer • Careful integration between optical & packet layer will be required • We will live in a hybrid world for the foreseeable future • 40G will emerge when customers demand it
