Abstract

The large capacity ultra long haul（ULH） transmission is a very promising technology for future

this paper introduces the 160×10 Gbit/s system transmission experiment over actual 3 040 km G.652 fiber. The system uses C+L band and the channel interval is 50 GHz

adopting CS-RZ as the line code. The line rate is 10.7 Gbit/s. Using the broadband characteristics of the distributed Raman amplification technology

and compensating the disperse in C+L band at one time

we have greatly reduced the system costs as compared to separate band compensation. The experimental results show that after the 3 040 km transmission

Q value is lager than 4.29

the optical path penalty is smaller than 3.5 dB

the OSNR is lager than 15 dB

and the system runs error free for continuous 24 hours.
