背景技术
无线小站是无线通信产品实现室内网络覆盖的一个重要支持终端，作为射频信号发出的最后末枝，小站产品的信号覆盖范围和耗能大小，直接影响着一栋室内建筑，或者一个区域内投放终端的数量和持续运营的电能成本；因此射频信号覆盖范围和功耗，成为了小站类射频终端产品的重要竞争力指标。
目前，在无线小站的传统通用公共无线电接口(Common Public Radio Interface，CPRI)架构下，射频拉远单元内需事先模拟转数字信号的大功率处理要求，在固定体积的约束下，对产品的散热、产品功耗、产品功率提升带来的极大的挑战。若可以将数字解调前移到射频拉远集线器(Remote Radio Unit HUB，RHUB)，则可释放射频拉远单元的体积、功耗等，提升竞争力，这就是新光载无线通信(Radio-Over-Fiber，ROF)架构。由于在对外接口连接器方案上，需要将模拟信号直接外传，因此产品的实现需要高隔离射频连接器。如何设计高隔离度的射频连接器是当前亟待解决的问题。
