The etiology of many neurodegenerative diseases is unknown, but a number of studies indicate that a combination of both genetic and environmental factors contribute to the progression of disease. Expo...
SMF铁路数字信息系统是基于莱钢运输部局域网,以各站分散的铁路信号调度监督信息、铁路站场工业电视监控 信息、铁路货运统计信息为基础,通过建立铁路信号调度监督信息数据库,实现站场信号实时平面示意图综合显示、站场实 时监控、调度作业图表自动绘制、运输作业统计表自动生成等,从而搭建起莱钢铁路运输调度指挥管理中心,达到了莱钢铁 路运输组织管理无缝隙高效运作。
We report on mode field diameter changes of -31% due to UV-induced core refractive index changes of ≤10 -2 in SMF-28e leading to a loss reduction of 0.83 dB between SMF-28e and a dispersion compensati...
432Gbit/s O-OFDM QPSK transmitter has been proposed and experimentally demonstrated.After transmission over 400km standard single-mode fiber (SMF), the measured BER is smaller than 2 ×10 -5 .
We report the world’s first transmission of a 288Gb/s Ethernet Superchannel over 124km un-repeatered link of field-installed SMF using direct-detected NRZ Coherent WDM with a 2dB OSNR transmission pen...
High-performance 1.3-  m InGaAlAs electroabsorption modulator integrated with DFB laser module for metro-area 100-Gbi/s Ethernet system (100GBASE-ER4) has been realized. Long-reach (40 km) err...
We demonstrate the record capacity-distance product of 48.2 Petabit/s.km by using 111-Gb/s no-guard-interval coherent OFDM with 2-b/s/Hz spectral efficiency.
A REAMSOA chip is characterized as part of an ONU in single-pass and then bidirectional upstream 10 Gbit/s PON configurations. Chromatic dispersion and Rayleigh backscattering impacts are assessed.
One seventh miniaturized EA-DFB laser module with +/-100ps/nm dispersion tolerance at 25Gbps was demonstrated. It’s the world’s first module applicable to the small 100Gbps Ethernet transceiver.
Transmission of Pol-Mux 110Gb/s RZ-DQPSK signal with automatic Pol-Dmux at receiver over straight 2,000-km SMF line with +3dBm/ch shows that the performance is mainly governed by OSNR and PMD.
We investigated transmission of 50Gb/s 16QAM over 50km SMF. 16QAM was electro-optically synthesized with a quad-parallel MZM; demodulated by off-line digital homodyne employing electric equalizers.
