What is the diameter of the ferrule in an LC connector?

1.0 mm
1.25 mm
1.5 mm
2.0 mm

The correct answer is: 1.25 mm

The diameter of the ferrule in an LC connector is 1.25 mm. This specification is important in fiber optic connections because the ferrule holds the optical fiber in place and ensures proper alignment with the mating surface of another connector or device. The 1.25 mm diameter allows the LC connector to maintain a compact design, enabling higher density patch panels and installations. This compact design is particularly useful in environments where space is limited, making LC connectors widely used in telecommunications and data networks. Understanding the specifications of connectors like the LC ferrule is essential for proper installation and maintenance of fiber optic systems.
