MCI NG Fiber Development Objectives
• Next Generation fiber is designed for ULH (at 3000~6000
km), DWDM, 10G/40G network deployment
• Fiber parameters enable 20 Pb/s*km for both short fat (2000
10 Gb/s wavelengths at 1000 km) and long thin (700 10 Gb/s
wavelengths at 3000 km) architectures or equivalent
wavelengths at 40G
• Eliminate transport O/E/O
• Introduce pass-through and multi-degree ROADM
• Increase dispersion and PMD tolerance
• Easier slope compensation and lower loss
• Enhance new hybrid amplifier development
• THIS NG FIBER WILL SUPPORT 40G

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
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
