1.引言随着密集波分复用技术及高速数字同步传输技术的发展,光纤通信技术在互联网、电话、电视等领域已得到了广泛应用。然而,全球各地基础建设和自然灾害,不可避免会对埋设的光缆造成危害,导致光缆网运营维护越来越困难。光缆网运营维护涉及到多个层面的工作,在业务方面,当光缆出现故障甚至断裂的情况下需要保证业务能够连续不中断;在维护方面,希望
1. Introduction With the development of dense wavelength division multiplexing and high-speed digital synchronous transmission technology, optical fiber communication technology has been widely applied in the fields of internet, telephone and television. However, infrastructure and natural disasters around the world inevitably endanger the optical fiber cables laid, which makes the operation and maintenance of the optical fiber network more and more difficult. Optical fiber network operation and maintenance involves multiple levels of work, in terms of business, when the optical cable fails or even broken under the circumstances need to ensure that business can continue without interruption; in the maintenance, hope
