泄漏电缆选型规范的研究

摘要

以往的泄漏电缆选型规范中，常将单一频段的两个指标分开来进行限定，但以这种规范来进行泄漏电缆的选型已经不能满足现阶段通信建设的需求。对此讨论了如何根据传输损耗和耦合损耗这两个指标以及多频段需求来对泄漏电缆进行选型，并对泄漏电缆在不同频段的优劣进行了比较。%In the previous model selection standard of leaky cable, the two indicators(transmission loss and coupling loss) of a single band is usually separate to qualify, however, this standard to select leaky cable can’t meet the current needs of communication construction any more. The method to choose a proper leaky cable according to the transmission loss and coupling loss as well as the multi-band needs is discussed. The pros and cons of leaky cable are compared in different frequency bands.
