一、主要情况我院于5月份初步建成能开通120路电话的光缆通信实验系统,其目的是检查我院近年来光纤通信科研成果,通过联试以便发现问题,暴露矛盾,找出差距,为今后科研提供改进的依据。该联试系统原计划通信距离为2公里,由于主要设备和器件的性能超过原设计指标,为了考查我院光纤光缆、光电器件和光端机的性能,因此将其一个传输方向在不加装中继器情况下,延长其通信距离。5月16日开通2.03公里后,经过联试,不断调测改进,在5月30日
First, the main situation Our hospital initially built in May to open a 120-channel optical fiber cable communication experiment system, whose purpose is to check our hospital in recent years, optical fiber communication scientific research, through the joint test in order to identify problems, reveal the contradictions, to find out the gap between Future research provides the basis for improvement. The joint test system originally planned communication distance of 2 km, due to the performance of major equipment and devices than the original design indicators, in order to examine the performance of our hospital optical fiber and cable, optoelectronic devices and Optical, it will be a transmission without relay In case of device, extend its communication distance. After opening 2.03 km on May 16, after a series of tests, the commissioning and improvement will continue on May 30
