SFP Optical module VS fiber Media converter
842 2022-02-26
What is the difference between an optical module and a fiber ethernet Media converter?

1. a. Optical modules are functional modules, which belong to accessories and cannot be used alone. They can only be used in switches and devices with optical module slots;
b. The optical fiber transceiver is a functional device, which is a separate device, and can be used alone with the power supply.

2. a. The optical module itself simplifies the network and reduces the points of failure;
b. Using too many fiber ethernet Media converters will increase the failure rate and occupy too much storage space in the cabinet.

3. a. The optical module supports hot swap and flexible configuration;
b. The fiber ethernet Media converter is a fixed specification, and it is difficult to replace and upgrade.

4. a. Optical modules are more expensive than fiber ethernet Media converters, but they are relatively stable and not easy to break;
b. Fiber ethernet Media converter are relatively economical and practical, but the power adapter, fiber status, network cable status and other factors must be considered, and the transmission loss accounts for about 30%.

5. a. Optical modules are mainly used for optical interfaces of optical network communication equipment such as aggregation switches, core routers, DSLAM, OLT and other equipment, such as: computer video, data communication, wireless voice communication and other optical fiber network backbone networks;
b. Fiber ethernet Media converter are used in actual network environments that cannot be covered by Ethernet cables and must use optical fibers to extend the transmission distance, and are usually located in the access layer applications of broadband metropolitan area networks, such as: high-definition video image transmission for monitoring and security engineering As well as fiber optic last mile connections to the metropolitan area network and beyond.


What should I pay attention to when pairing an optical module with a fiber ethernet Media converter?

1. The wavelength and transmission distance must be the same. For example, the wavelength is 1310nm or 850nm at the same time, and the transmission distance is 10km.
2. Optical fiber jumpers or pigtails must be connected to the same interface. Generally, optical fiber transceivers use SC ports, and optical modules use LC ports.
3. The speed of the fiber Media converter and the optical module must be the same. For example, the gigabit transceiver corresponds to the 1.25G optical module, 100M to 100M, and 10M to 1G.
4. The fiber types of the optical modules must be the same, single fiber to single fiber, dual fiber to dual fiber
