随着数据率的增加和比较大的中继器间距,对光纤传输系统的要求越来越严格,而且容限己经变得最小。特别是在光学方面的比较好的测试设备是很需要的,以用于测量和保证技术指标。同时,对高性能传输设备的要求也在迅速增长,必须建立生产能力和产生测试程序。为了满足这一要求,必须缩短测试时 As data rates increase and relatively large repeater spacing becomes more stringent for optical fiber transmission systems, and tolerances have become minimal. Especially in the optical test equipment is relatively good for the measurement and to ensure that technical indicators. At the same time, the demand for high-performance transmission equipment is also growing rapidly, and production capacity and test procedures must be established. In order to meet this requirement, the test time must be shortened
