通过对现有拉远方式的研究,利用PDH光端机对诺西的EOCA光路板进行了替换,改变了诺西2G FLEXI第五代基站原有的拉远方式,从而实现第五代基站的灵活应用。这种拉远模型的改变可避免诺西EOCA板的采购成本,又减少维护点,提高了工作效率。此种改造方式已进行了多个站点的现网应用,具备推广价值。 Through the research of existing remote ways, the use of PDH optical transmitter to replace the Noci EOCA optical circuit board has changed the original North Fargo 2GFLEXI fifth generation base station remote way, in order to achieve the fifth generation base station flexible application. This remote model change to avoid Nokia Siemens EOCA board procurement costs, but also to reduce maintenance points, improve work efficiency. This transformation has been carried out at more sites in the existing network applications, with promotional value.
