The duplex LC connector is a connector for connecting SFP optical modules and is widely used in fiber optic interconnection applications in local area networks and data centers. However, with the development of the times, people have developed a variety of duplex LC connector variants. This tutorial will introduce a variety of duplex LC connectors in detail.
Standard duplex LC connector
The standard duplex LC connector is the first generation of duplex LC connector, developed by Lucent Technologies. This connector is made of an easy-to-operate modular jack (RJ) latch mechanism, and the size of the pin and sleeve used is half the size of ordinary SC, FC and other connectors, which is 1.25mm. Now, the standard duplex LC connector dominates in many fiber optic network connections.
Mini Duplex LC Connector
The mini duplex LC connector is a variant of the standard duplex LC connector. Its structure is the same as that of the standard duplex LC connector, except that the spacing between the ferrules is reduced to 5.25 mm (the spacing between the ferrules of the standard duplex LC connector is 6.25 mm). The mini duplex LC connector is mainly used with small SFP optical modules to provide higher-density fiber connections.
Duplex LC Uniboot Connector
The duplex LC Uniboot connector is a design in which two optical fibers share a protective cover, and the optical cable connected to it is a 2-core optical cable. Compared with the standard duplex LC connector, the duplex LC Uniboot connector has a more compact structure and is an ideal solution for high-density wiring applications.
It should be noted that the protective cover of the duplex LC connector can be configured into different styles according to specific needs. In addition to the cover types of standard LC connectors and duplex LC Uniboot connectors, there are also mini covers, BTW covers, short covers, 45/90. Angle covers, etc.
High-density duplex LC connector
Anyone who has experience in managing high-density wiring systems knows that it is not easy to plug and unplug the duplex LC connectors on the adapter panel by hand, and this practice is not conducive to the stability of the wiring system. If high-density duplex LC connectors are used for wiring, the plugging and unplugging of the connectors is much easier, because the high-density duplex LC connector has an additional push-pull bar design, and the operator only needs to push and pull the push-pull bar to easily plug and unplug the connector. Note: Some high-density duplex LC connectors also combine the compact structure design of the duplex LC Uniboot connector, which is more suitable for high-density wiring applications.
Duplex LC lock connector
The colors of the duplex LC lock connector are more diverse, with a total of 12 colors, each color corresponds to a lock design, so only duplex LC lock connectors and adapters of the same color can be used in pairs. The design of this duplex LC lock connector can effectively avoid mixed insertion between similar connectors, and to a certain extent physically isolate the network, so it plays an important role in the security of the data center network.
Conclusion
This tutorial introduces several common duplex LC connector variants on the FiberLife. With the development of technology, the variants of duplex LC connectors will become more and more diverse. No matter how the duplex LC connector changes, we should choose the most suitable duplex LC connector solution according to the specific application.
