两者的区别在于：使用要求不同、特点不同、应用要求不同。
1、使用要求不同：光分配箱不需要外部能量，只要有输入光即可；光缆交接箱为光缆引入光缆交接箱后，经固定、端接、配纤以后，使用跳纤将主干层光缆和配线层光缆连通。
2、特点不同：光分配箱具有多个输入端和多个输出端的光纤汇接器件，常用于光信号的耦合、分支和分配；光缆交接箱从局端到各光缆交接箱只使用一条大对数光缆连接的网络结构，它使用在业务量少，范围不大的非重点地区。
3、应用要求不同：光分配箱在对正常链路进行分光时，会按照光功率相对应的比例分配到多条分光后的链路；光缆交接箱的用户侧光缆，可以根据用户的发展需求进行逐一上箱，交接箱容量的选择可以以288芯为主。

两者的区别在于：使用功能不同、应用场景也不同。但是又有着密切关系，为什么呢、光分配线箱是光缆交接箱下一级布线设备、光缆交接箱是光分配线箱上一分支设备，他们起着相互相成合作理念。看一下光缆交接箱作用是一种为主干层光缆、配线层光缆提供光缆成端、跳接的交接设备。光缆引入光缆交接箱后，经固定、端接、配纤以后，使用跳纤将主干层光缆和配线层光缆连通。光分配箱作用是用于光缆与光通信设备的配线连接，通过配线箱内的适配器，用光跳线引出光信号，实现光配线功能。适用于光缆和配线尾纤的保护性连接，也适用于光纤接入网中的光纤终端点采用。这样一来、应该都懂了吧、再不懂、作者再用图文来给演示一下。
288芯光缆交接箱用于一级分光
144芯共建共享光缆交接箱用于主干光缆
共建共享576芯光缆交接箱用三网主干光
576芯光缆交接箱用于室外主干光缆
48芯光分配箱用于二级分光
1比16光分配箱用墙壁
SMC1比16用于室外电杆
SMC48芯光分配箱用楼道
镀锌板光分配箱用于室外墙壁
光缆交接箱参数
光分配箱一般在光交箱下游，安装在楼道，楼旁墙壁灯。
里面一般安装分光器、汇集用户皮线光缆.
箱体较小，价格便宜，技术含量小、工艺简单。
光交箱可以看做一个小型、没有设备的机房，光缆中转站，上接机房设备、主干光缆，下接众多配线光缆，安装熔纤单元、分光器等。
箱体一般较大、价格较贵、技术含量较高、重、工艺复杂。
