• Eliminate transport O/E/O

• Introduce pass-through and multi-degree ROADM

• Increase dispersion and PMD tolerance

• Easier slope compensation and lower loss

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

31MCI Confidential

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.

Summary

34MCI Confidential

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
