Duplex fiber connectors are available in a variety of styles, including LC, SC, ST, and FC. They are typically used in high-speed data transmission applications, such as Ethernet and Fibre Channel. Duplex fiber connectors are easy to install and provide reliable performance. They are also highly resistant to dust, moisture, and other environmental factors.
