OPGW使用寿命及光中继路由可用性问题

OPGW Service Life and Optical Relay Routing Availability

光纤复合架空地线(OPGW)具有电力架空地线和通信光缆双重功能,且具有可靠性高、抗自然灾害能力强、不易被人为破坏、影响工程方案可行性的因素少、施工难度小、工程建设附加费用低、性能价格比高、使用寿命长、通信局(站)之间的光缆路由长度往往比其他方式架(敷)设的光缆短、运行维护费用低等优势。

Optical fiber composite overhead ground wire (OPGW) has the dual functions of power overhead ground wire and communication optical cable,and it has high reliability,strong resistance to natural disasters,not easy to be destroyed by human,less factors affecting the feasibility of Engineering scheme,less construction difficulty,low additional cost of Engineering construction,high performance-price ratio,long service life,and the length of optical cable routing between communication bureaus( stations). Compared with other ways,the former has the advantages of shorter cable length and lower operation and maintenance costs.
