Abstract
Experimental investigations of 112 Gb/s PM-QPSK transmission are reviewed
for systems with 100 km spans and EDFA-only amplification, 200 km spans and
hybrid amplification (distributed Raman amplification (DRA) and EDFA), and
100 km spans and DRA-only amplification. By taking advantage
of optical fibers with ultra-low loss and very large effective area, transmission
distances of 7200 km, 5400 km and 10 200 km, respectively, were achieved for multi-channel transmission
with a 50 GHz channel spacing. For the first of these systems, the impact
of the signal processing algorithms on the long-haul bit error ratio performance
is examined with an emphasis on the sensitivity to the values of key algorithm
parameters.
