世界范围内的电信网络正在迅速演变为除了传统的语音电话之外，还承载互联网、有线电视和其他数据流量的宽带业务的系统，运营商在其网络中安装的互联网设备正在大量增加。这一发展对现有的电源接口标准产生了影响。欧洲电信标准化协会（ETSI）是欧洲共同体和欧洲自由贸易联盟认可的区域性组织，是欧洲三个官方标准制定机构之一，负责整个电信领域的标准化，包括无线电、广播和私人电信。接口的配电要求是什么？用于-48V/-60V的A”在ETSI EN 300 132-2中标准化。传统电信设备与新型宽带和IT设备在中接网的融合，需要一种更高效率和可靠性的供电和安全安装（接地、接地、电池）解决方案。2003年发布了ETSI EN 300 132-3，用于直接为传输设备供电400 V。在2003年、2004年、2005年、2006年、2007年和2008年以及全球倡议的几次研讨会上，讨论了与几个试点项目有关的不同经验和解决方案。在电力装置中广泛使用直流提供了高能源效率，并改善了交流配电网络的电能质量。本次演讲将简要介绍过去6年的标准化工作，以及在全球范围内实现新型互联网设备更高效供电的实际结果、问题和趋势。
Telecommunications networks worldwide are evolving rapidly into systems carrying over the broadband services with Internet, cable TV and other data traffic in addition to traditional voice telephony, and operators are seeing a large increase in Internet equipment installed in their networks. This development has influence to the actual existing standards for the power supply interfaces. European Telecommunication Standardization Institute (ETSI) is the regional organization that is recognized by the EC and EFTA as one of the three official standards-making bodies in Europe, and is responsible for standardization in the whole field of telecommunications, including radio, broadcasting and private telecommunications. The requirements for the power distribution to the interface ?A" for -48V/-60V are standardized in the ETSI EN 300 132-2. The mixing of the traditional telecommunication equipment with new broadband and IT equipment in the Central Office (CO) and access network need a solution for the powering and safe installation (earthing, grounding, batteries) with higher efficiency and reliability. In the year 2003 was published the ETSI EN 300 132-3 for direct powering the transmission equipment with 400 V. In several workshops on the INTELEC 2003, 2004, 2005, 2006, 2007 and 2008 and worldwide initiatives were discussed the different experiences and solutions in connection to several pilot projects. A wide use of DC in electrical installations offers high energy efficiency, and improves power quality in the AC distribution network. The presentation will give a small overview to the standardization in the last 6 years with the actual results, problems and trends in the worldwide realization of higher efficient powering of the new internet equipment.
