Long-distance transmission over standard fiber by use of mid-way phase conjugation

摘要

In this letter, we predict transmission over more than 6000 km using standard fiber with the application of mid-way phase-conjugation in a 1.55-μm, 10-Gb/s IM/DD system with in-line amplifiers for the power penalty at BER=10-9, which is less than 6 dB; the system must operate with an average power into the fiber within the range of -5 to 5 dBm
