据“国防半导体”杂志2002年第5期报道,贝尔实验室和朗讯公司技术研发分部的科学家已经用每秒传送2.56Tb 的速度打破了高带宽、超长距离传送的新记录,使通信距离达4000公里。此前的传送记录为1.60Tb/s、2000公里。朗讯光集团总裁认为,这一突破将会给用户带来经济利益。这一超长、全光纤传送记录是用64信道密度波长分隔多路传输制(DWDM)获得的。每个信道以
According to National Defense Semiconductor Magazine No. 5 of 2002, scientists at Bell Labs and Lucent Technologies’ R & D division have broken new records of high-bandwidth, ultra-long-haul transmission at speeds of 2.56Tb per second, enabling communication distances Up to 4000 km. Prior to the transmission record of 1.60Tb / s, 2000 km. Lucent Optical Group president believes that this breakthrough will bring economic benefits to users. This ultra-long, all-optical transport record is obtained using 64 Channel Density Wavelength Division Multiplexing (DWDM). Each channel to
