光纤传输具有频带宽、损耗低、不受电磁波干扰、图像质量稳定等优点,加之光设备、光缆的成本大幅度下降,各有线电视台(站)多利用光纤作为超干线、主干线、干线、支线传送广播电视信号及开展多功能服务,因此对光传输设备的维护工作就显得更为重要。现从光传输设备的故障分析及维护措施角度谈几点建议。
Optical fiber transmission has the advantages of wide frequency band, low loss, no interference from electromagnetic waves and stable image quality. Moreover, the cost of optical equipment and optical cables is greatly reduced. All the cable stations (optical fiber stations) use optical fibers as super-trunk lines, trunk lines, trunk lines, Transmit radio and television signals and carry out multi-functional services, maintenance of optical transmission equipment is even more important. Now from the optical transmission equipment failure analysis and maintenance measures to talk about a few suggestions.
