You will find a wide array of fiber optic connectors in the market. They are all made in different ways to help in fiber-optic networks. While they are many, here are the most common types that you should know:
Subscriber Connector (SC)

This type of SC Fast Connector is quite large when it comes to size. Bwinners SC Fast Connector might be the best option if you want a connector that you can use with extenders.
When it comes to shape, the SC Fast Connector is square. It uses a simple push-pull mechanism with a 2.5mm ferrule to hold into where you place it. It is also versatile that you can use in single-mode and multimode fiber.
Compared to other types, SC Fast Connector are more durable, low cost, and simple to use.
Straight Top Connector (ST)

If you are doing a commercial network system or wiring, then this might be what you need. It uses a socket and a bayonet plug to complete the connection process. Its ferrule is also 2.5mm like that of the SC connector.
To stay in place and perform its function, this connector has a bayonet lock that holds it. So, if you want a connector that best serves in a tight space, you may consider this option.
For better performance, you can mix ST with FDDI, ESON, FC, and SC connectors. You only need a hybrid adaptor to complete this process.
You can plug as well as unplug ST connectors easily. Also, note that you can only use them at the end of a multi-code cable.
Lucent Connector (LC)

LC Fast Connector is a bit smaller in size. If you compare it with the SC Fast Connector type, the LC Fast Connector is almost half the other. The shape is square, and it works best if you want to terminate multiple fibers.
LC connector’s ferrule is about 1.25mm, and these connectors use a clip to create a connection that is a duplex. You can thus use them in single as well as multimode fiber optic cables.
For areas where there are multiple connections and the space is relatively small, the LC Fast Connectors work well.
Fiber Distributed Data Interface (FDDI) Connector

If you want a reliable connector for your data transmission network, the FDDI might be your best bet. It has a large container that houses two ferrules.
You can use it for connection to the local area network. To hold things in place, this connector uses a squeeze tab mechanism.
For better connection and performance in your network, you can mate the FDDI connector with SC and ST connectors.
Unlike other connectors, the FDDI is effective for long-distance data transmission networks.
