It can be divided into non network managed fiber optic transceivers and network managed fiber optic transceivers. Most operators hope that all devices in their networks can be remotely managed, and fiber optic transceiver products, like switches and routers, are gradually developing in this direction. For fiber optic transceivers that can be managed through network, they can be further divided into office end network managed and user end network managed. The fiber optic transceivers that can be managed on the office end are mainly rack based products, most of which adopt a master-slave management structure. The main network management module needs to poll the network management information on its own rack, and on the other hand, collect all the information on the slave racks, and then summarize and submit it to the network management server. The OL200 series network managed fiber optic transceiver products provided by Wuhan FiberHome Network support a network management structure of 1 (master)+9 (slave), and can manage up to 150 fiber optic transceivers at once.

User side network management can be mainly divided into three ways: the first is to run specific protocols between the office and client devices, which are responsible for sending client status information to the office, processing these status information through the CPU of the office device, and submitting it to the network management server; The second type is that the fiber optic transceiver at the office can detect the optical power on the optical port, so when there is a problem on the optical path, it can be determined whether it is a problem on the fiber optic or a malfunction of the user's equipment based on the optical power; The third method is to install a master CPU on the fiber optic transceiver of the user end, so that the network management system can monitor the working status of the user end equipment on the one hand, and also achieve remote configuration and remote restart. Among these three user side network management methods, the first two are strictly limited to remote monitoring of user side devices, while the third one is truly remote network management. However, due to the addition of a CPU on the user end in the third method, which also increases the cost of the user end device, the first two methods will have more advantages in terms of price. With the increasing demand for device network management from operators, it is believed that the network management of fiber optic transceivers will become increasingly practical and intelligent.
