市内宽带通信电缆的研制成功,带给基础电信网络ADSL宽带接入实现更好的用户和Internet的高速连接,解决了利用双绞铜线宽带接入Internet的“瓶颈”问题。广意HYAB宽带电缆于2003年元月份通过了信息产业部检测中心的检测,获得了广东省科技厅新产品技术签定书。2003年6月份在北京通信公司现场演示成功,获得北京通信公司的好评。2003年11月至2004年元月,广意HYAB宽带电缆在顺德电信局做大长度(4～6公里)、多终端(80台电脑,20部电话)的应用演示,再次获得成功,已通过了信息产业部对试验电缆的性能测试和ADSL接入网的终端上网下载考核。广意HYAB电缆已达到30兆以上的性能要求,并通过了广东省电信公司的应用验收。本文比较分析了在ADSL应用中HSYA电缆与HYA电缆的差异。
The success of the development of broadband communication cables in the city brought ADSL broadband access to basic telecom networks to realize better high-speed connection between users and the Internet and solved the “bottleneck” problem of using twisted pair copper wires to access the Internet. The idea of HYAB broadband cable in January 2003 passed the testing of the Ministry of Information Industry Testing Center, won the Guangdong Provincial Department of Science and Technology new product technology signatures. In June 2003, the successful demonstration was made at Beijing Communication Company and was well received by Beijing Communication Company. From November 2003 to January 2004, HYAB Broadband Cable succeeded again in Shunde Telecom Bureau for demonstrating its application length of 4 to 6 km and multi-terminal (80 computers and 20 phones) and passed Ministry of Information Industry of the test cable performance testing and ADSL access network terminal Internet download assessment. Connotation HYAB cable has reached more than 30 trillion performance requirements, and adopted the Guangdong Provincial Telecommunications Company’s application acceptance. This article compares the differences between HSYA cables and HYA cables in ADSL applications.
