Abstract
The reconfiguration of channel or wavelength routes in optically
transparent mesh networks can lead to deviations in channel power that may
impact transmission performance. A new experimental approach, applied
constant gain, is used to maintain constant gain in a circulating loop
enabling the study of gain error effects on long-haul transmission under
reconfigured channel loading. Using this technique we examine a number of
channel configurations and system tuning operations for both full-span
dispersion-compensated and optimized dispersion-managed systems. For each
system design, large power divergence was observed with a maximum of 15 dB
at 2240 km, when switching was implemented without additional system tuning.
For a bit error rate of $10 ^{-3}$, the maximum number of loop circulations was reduced by up to
33%.
