摘要
针对2013年以来逐步建设的1 310 nm光网络存在的故障多、可靠性差、管理难度大、网络扩容性不高和扩容成本高的问题,文章讨论了采用1 550 nm+EDFA光传输替代1 310 nm光传输模式的优势,介绍了宾川县乡村有线电视网络1 310 nm升级改造为1 550 nm光传输的设计思路和技术方案。
Aiming at the problems of many faults, poor reliability, difficulty in management, low capacity and high cost of network expansion, 1310 nm optical network has been built since 2013. This paper discusses the advantages of replacing 1310 nm optical transmission mode with 1550 nm EDFA optical transmission, and introduces the design idea and technical scheme of upgrading 1310 nm to 1550 nm optical transmission from 1310 nm in rural cable television network in Binchuan county.
