Single mode fiber connectors are used to connect single mode fibers for data transmission. They are designed to provide low insertion loss and back reflection, and are available in a variety of styles, including FC, SC, ST, LC and MU. They are typically used in long-distance applications, such as in data centers, telecom networks and CATV systems. Single mode fiber connectors are also used in high-speed data transmission, such as 10G, 40G and 100G Ethernet. They are designed to be durable and reliable, and are available in both male and female versions.
