Types of Duplex Connectors
3. Not all connectors are created equal.
While the fundamental principle remains the same, duplex connectors come in various types, each designed for specific applications and environments. Understanding these different types can help you choose the right connector for your needs, avoiding any frustrating connection issues. Let’s take a quick tour of some common duplex connector varieties.
First up, we have the LC duplex connector. This is a popular choice for fiber optic applications due to its small size and high performance. It uses a “latch and connect” mechanism, making it easy to install and remove. LC connectors are known for their reliability and are often used in data centers and telecommunications equipment. If you need to connect some fiber cables, chances are you are going to run into these.
Next, we have the SC duplex connector. SC stands for “Subscriber Connector,” and it’s another common type of fiber optic connector. It’s a bit larger than the LC connector and uses a “push-pull” locking mechanism. SC connectors are known for their robustness and are often used in older fiber optic networks. While not as compact as LCs, they are still widely used in various applications. Their widespread uses are a testament to the simplicity of the design.
Then, there’s the ST duplex connector. ST stands for “Straight Tip,” and it’s an older type of fiber optic connector that uses a bayonet-style locking mechanism. ST connectors are less common these days, but you might still find them in some older installations. While they aren’t the flashiest connectors around, they get the job done. This is a common thread amongst all of the duplex connectors.
Finally, let’s not forget the audio duplex connectors, such as the 3.5mm (1/8 inch) and 6.35mm (1/4 inch) stereo jacks. These connectors are ubiquitous in audio equipment and carry both the left and right audio channels. They are simple, reliable, and have been around for ages. Theyre so common you probably have a handful lying around somewhere.
