When you buy an optical module, the type of fiber connector must be one of the main factors you consider. Choosing the right fiber connector can not only improve propagation efficiency and reduce loss, but also have an important impact on the stability and compatibility of the connection with external fiber optic networks and other equipment. So do you know what are the differences between the connectors we commonly use, and how to choose according to their characteristics? Next, we will take you to compare and understand the commonly used optical fiber connectors(SC, LC, MTP/MPO) from three aspects:
Appearance structure
The SC connector has a blue rectangular shape and adopts a push-pull connection, which makes it easy to connect when using the SC connector and has a small chance of poor contact. The LC connector is smaller than the SC connector and has a blue appearance, and uses a modular jack (RJ) latching mechanism that allows for easy tooling and easy identification. MTP/MPO connectors are rectangular in appearance, with ferrule design, precise internal design, relatively large in size. But you need to pay attention to correctly match the connection of male and female when connecting during use.
Application scenarios
People widely use SC connectors in routers. They are also widely used in optical fiber communication equipment, such as optical fiber transceivers and optical fiber switches. In addition, when data centers require stable and efficient transmission, SC connectors are also suitable. Compared with SC fiber optic connectors, you may be familiar with LC connectors. Because LC connectors have an important use case – SFP optical module connection, you can choose LC simplex or LC duplex connectors according to your actual needs. In addition, LC connectors fit well with routers and people widely use them in high-power, low-loss network equipment. MPO/MTP connectors are mainly used for high-density cabling in data centers. They are suitable for 40G/100G optical transceivers and above network cabling and can meet the requirements of high-speed transmission and data capacity. MPO/MTP connectors are versatile in a variety of cabling scenarios in racks or cabinets. People widely use them for short-distance direct connections, duplex fiber interconnections, and 400G direct connections.
Performance characteristics
All three fiber optic connectors play a good role in the use process. The SC connector has strong compatibility and can connect to different optical fiber equipment. The LC connector is small in size, low in loss and easy to connect, and is suitable for high-density wiring. Although the MTP/MPO connector is relatively large in size. MTP/MPO connector supports the simultaneous connection of multiple transmission channels, has high-density connection capabilities, and greatly improves the network capacity.
Summary
SC, LC, MTP/MPO connectors are unique in their own way, and you can choose the most suitable product for your different needs. If you still have any questions after reading this article, you can contact us and we will answer them for you.
