随着改革开放的深入和城乡经济的迅速发展，国家相关部门提出了对社会治安进行综合治理的要求，并把创建安全文明小区作为其中的一项重要内容。
EPON以其组网方便、覆盖面积大的优点在小区监控中得到大量应用。EPON支持点对多点通信，头端OLT设备的1个PON可承载32个远端ONU设备，且头端OLT与远端ONU之间为由分光器和光纤组成的无源光网络，不需供电；如图中所示，在监控机房配备OLT设备，OLT设备接入光纤后在小区中心地带进行一级分光，分光器的各个支纤与光纤相连到达小区的不同区域，然后进行再次分光，分光器的多个支纤与光纤相连到达小区区域的各个楼栋，在楼栋接入ONU设备和IP摄像头即可完成监控图像到监控机房的传输，EPON的这种灵活组网方式不仅组网方便，覆盖面积大，且扩容简单，为整个监控项目的建设、维护提供极大的便利。
