The LC ST connector is a type of fiber optic connector used in fiber optic networks. It is a small form factor connector that is used to connect two fiber optic cables together. It is a popular choice for high-speed data transmission due to its low insertion loss and high return loss. The LC ST connector is a duplex connector, meaning it has two connectors, one for transmitting data and one for receiving data. It is also known as a "push-pull" connector because it requires a push-pull motion to connect and disconnect the two cables. The LC ST connector is a reliable and cost-effective solution for connecting fiber optic cables in a variety of applications.
