We succeed in the long-haul (1,280km) transmission of a 120-Gb/s PDM 64-QAM signal. The transmission distance was extended from 800 km to 1,280 km by a multi-stage nonlinear compensation technique that mitigates the intra-channel nonlinearities.
Experimental performance evaluation of SPM compensation and its application in optical transport network is introduced. Experimental results show transmission distances of 100 Gbps signal reaches 16,340 and 12,015 km in single-channel and 10-ch WDM conditions respectively.
Future optical transport networks should offer 10-Tb/s- class total capacity, and must be able to transport 100- Gb/s-class client signal transparently as well. Advanced modulation schemes for optical signals, such as differential quadrature phase-shift keying (DQPSK) and orthogonal frequency-division multiplexing (OFDM), are promising for such large-capacity networking. In this paper, highspeed optical...
This paper reviews recent progress in 100-Gb/s-class ultra-high speed optical OFDM transmission technologies. We describe system configuration based on optical multiplexing/demultiplexing and transmission performances.
This paper describes 100-Gb/s-class high-speed and large-capacity optical transmission technologies with focus on the modulation formats and high-speed optical/electrical devices. First, we review the recent progress of 100-Gb/s-class transmission technologies. We then discuss the transmission characteristics of several promising modulation formats with the line rate of 111 Gb/s. Next, we show the...
Abstract: We successfully demonstrate transparent 10GbE-LANPHY transport in 44.6-Gbit/s RZ-DQPSK WDM transmission for the first time. A single-chip 43/44-Gbit/s OTN framer LSI that supports fully transparent STM-64/10GbE multiplexing and DQPSK precoding are adopted.
43-Gbit/s PMD-limited performances of CS-RZ and NRZ have been verified in a joint field trail. CS-RZ showed better performance than NRZ. 2/sup nd/-order PMD of 200 ps/sup 2/ was accommodated in principal state of polarization transmission with FEC.
PMD induced system outage probabilities have been measured in a joint field trial of NTT and DT. For outage evaluation 43-Gbit/s CS-RZ signals of the NTT WDM system were transmitted over selected high-PMD fiber links of DT's fiber network.
