Description

一种具有网络接口的模块 技术领域
本发明涉及光电通信技术领域，特别是涉及一种具有网络接口的模块。
背景技术
随着光通信行业的发展，光电通信模块的工作频率越来越高，其面对的电磁干扰也越来越强，对模块的EMC(Electromagnetic Compatibility，电磁兼容性，简写为EMC)性能产生了更高的要求，EMC分为EMS(Electromagnetic Susceptibility，电磁抗扰度，简写为EMS)和EMI(Electromagnetic Interference，电磁干扰，简写为EMI)两部分，EMS用来评估模块自身稳定性，EMI用来评估模块对外噪声水平。
为了提高模块的EMC，需要对模块进行针对性的改进，可通过接地的方式缓解静电耦合干扰和磁场耦合干扰，但现有模块中电路板接地较困难；也可以通过金属隔离的原理来控制某一区域的电场或磁场对另一区域的干扰，现有模块中仅靠外壳进行电磁屏蔽的方案，但外壳形成的屏蔽体存在缝隙，干扰信号无法被外壳完全隔离在外，特别是，由于随着频率的增高，高频干扰信号的波长变得与缝隙的尺寸相当，干扰信号通过孔缝进入外壳内，对光模块造成干扰，无法满足模块在高频状态下工作的电磁屏蔽需求。
同时，一些现有模块在安装时，需要通过专用辅助工具进行组装，工艺较繁琐，且水晶头插入插座后，由于没有足够有效的限位，网线受到外力拉扯时，容易脱出插座。
鉴于此，克服该现有技术所存在的缺陷是本技术领域亟待解决的问题。
