This paper demonstrates a record unrepeatered transmission with the capacity of 36 Tb/s ($90\times 400$ Gb/s) over 342.5 km (53.8dB) with C+L band transmission, using forward Raman pump, backward C+L ROPA, and ultra-low loss & large effective area fiber.Show More
This paper demonstrates a record unrepeatered transmission with the capacity of 33.6 Tb/s (42 × 800 Gb/s) over 302.7 km (47.52 dB) with a single fiber configuration, using forward Raman pump, backward ROPA, and ultra-low loss & large effective area fiber.Show More
Ultra-long single span hybrid BOTDR and Φ-OTDR system with ROPA technology is proposed. Using double heterodyne detection configuration, high order Raman amplifiers, cascaded RGUs, 208km unrepeatered real time simultaneous temperature and vibration measurement is achieved.Show More
We demonstrate record single-carrier 500Gb/s unrepeatered transmission over a single span of 431km with single fiber configuration, using optimized high-order Raman pump, forward and backward ROPAs, and optimal modulation format while using the same single ultra low loss with large effective area fiber for both signal and pumps.Show More
We report the results of 50G, 100G, 200G, 400G un- repeatered transmission aimed at achieving the longest distance without any inline active elements, this system realizes record single-carrier 50 Gb/s (PM-BPSK), 100 Gb/s (PS-QPSK), 200 Gb/s (PM-8QAM) and 400 Gb/s (PM-64QAM) unrepeatered transmission over 670.64 km with 103.95 dB span loss, 653.35 km with 101.27 dB span loss, 601.93 km with 93.3 d...Show More
We demonstrate unrepeatered transmission of single-carrier 400Gb/s over 482km and 4×400Gb/s over 449km distance with single fiber configuration, using optimal modulation format, forward and backward RGUs enabled by high-order Raman pumps and ultra-low loss & large effective area fiber.Show More
We demonstrated 2.5G unrepeatered transmission over 606.5km fiber by employing PM-BPSK format, FEC, ULL fiber and optimized ROPAs structure. To the best of our knowledge this is the longest unrepeatered 2.5G-based transmission distance.Show More
The nonlinear signal-noise interaction (NSNI) is analyzed in the bi-directional Raman amplified unrepeatered system with digital back-propagation (DBP) algorithm. When the DBP is applied at the receiver side, because in the DBP process the spontaneous Raman scattering is not dealt with, extra NSNI occurs, and because of the high power in the system, the extra NSNI is severe. By adopting split-DBP,...Show More
