随着NTT的贯横日本的光通信线路建设,我国光通信用的各种检测器件之需求量也大幅度地增加了。尤其是像光功率计、标准光源及故障位置检测装置(如光时域反射计)等为光通信所必需的基本检测器件,市场己确实开始感到需要。今后,除了NTT积极地将光缆引入干线的分支外,还有第二电电电缆公司的日本电信业务、日本高速通信光缆的敷设规划、全国各地电力公司的光缆网敷设计划,不久也会陆续急剧进展。我国光通信用的检测器的两大厂商是安藤电气公司和(?)公司。这两家公司生产了目前所必需的
With the NTT’s cross-Japan optical communications line construction, China’s optical communications with a variety of detection devices demand has also increased dramatically. In particular, markets such as optical power meters, standard light sources and fault location detection devices (such as optical time domain reflectometry) are essential test devices necessary for optical communications. In the future, apart from NTT’s active introduction of optical fiber cables into the trunk lines, there will also be plans for the Japanese telecommunications business of the Second Electric Cable Company, the laying of a Japanese high-speed communication optical cable, and the laying of the optical cable network of the electric power companies throughout the country, progress. The two major vendors of optical communication detectors in the country are Ando Electric and (?). The two companies produced what they needed today
