• Dispersion compensation fiber amplifiers. This type of dispersion compen-
sation fiber devices incorporate SRS to compensate both dispersion and
power loss.
• Development of dynamic tunable dispersion compensation devices. For sys-
tems with a bit rate greater than 40 Gb/s, very accurate dispersion control is
required. Such systems will neces sitate dynamic tunable dispersion devices
on a channel by channel basis.
• Better understanding of electronic dispersion compensation (EDC) technique
in terms of its capability and limitations. This will enable designing new
transmission and dispersion compensation fibers to work with EDC.
