按网管来分，可以分为网管型光纤收发器和非网管型光纤收发器。随着网络向着可运营可管理的方向发展，大多数运营商都希望自己网络中的所有设备均能做到可远程网管的程度，光纤收发器产品与交换机、路由器一样也逐步向这个方向发展。对于可网管的光纤收发器还可以细分为局端可网管和用户端可网管。局端可网管的光纤收发器主要是机架式产品，多采用主从式的管理结构，即一个主网管模块可串联N个从网管模块，每个从网管模块定期轮询它所在子架上所有光纤收发器的状态信息，向主网管模块提交。主网管模块一方面需要轮询自己机架上的网管信息，另一方面还需收集所有从子架上的信息，然后汇总并提交给网管服务器。如武汉烽火网络所提供的OL200系列网管型光纤收发器产品支持1（主） 9（从）的网管结构，一次性多可管理150个光纤收发器。
