英国电信研究实验室演示了以每秒几十兆比特的数据速率开通纤维光学通信线路的可行性。然而,这还不是最高水平的速度。业已证明:诸如那些越洋光缆之类的超大容量的光纤线路不必采用价格非常高的激光器。包括竞争者在内的一些参观者说:这一成果连同英国电信公司的其它科研项目使该公司在无源信号检测的新领域明显地处于领先地位。按照项目负责人Lutg Blank说:“在英国萨福克的英国电信公司的MartleshanHeath实验室所进行的实验室实验证明,在一条100公里长的光纤上实现了20Gb/s速率的模拟数据传输”。他还说:“从较长远的观点来看,50Gb/s的速率是可达到的,并且期望在近年内能建立较高速系统的现场试
BT Research demonstrated the feasibility of opening fiber optic communications at data rates of tens of megabits per second. However, this is not the highest level of speed. It has been proven that ultra-high-capacity fiber optic lines, such as those of transoceanic cables, do not have to use very expensive lasers. Some visitors, including competitors, said: “This result, along with BT’s other research projects, has clearly put the company a clear lead in new areas of passive signal detection. According to Lutg Blank, Project Leader, ”Lab experiments at the British Telecom’s MartlesHeath Laboratory in Suffolk prove that 20Gb / s analog data transmission is achieved over a 100 km fiber.“ He also said: ”In the longer term, 50Gb / s is achievable and it is expected that on-site trials will be able to establish higher-speed systems in recent years
