The LC connector was developed to meet the growing demand for smaller and easier-to-use fiber optic connectivity. With this
connector, space requirements on equipment bays, in distribution panels, and on wall plates has been reduced by 50%,
without sacrificing performance.

Common and proven technologies have been combined in the LC connector system to deliver a high performance and easy to
implement fiber optic interface. The industry standard RJ-45 telephone plug interface provides the reliable and robust latching
mechanism for this connector system while the time tested zirconia ceramic ferrule is used to terminate the fiber.

The Molex LC connectors are available in both simplex and duplex configurations. They are available in industry standard
beige and blue colors, and will accommodate 900µm buffered fiber and 1.6mm and 2.4mm jacketed cable. With its 6 position
tuning feature, the connector may be used to achieve unprecedented insertion loss performance by optimizing the alignment
of the fiber cores. Additionally, a versatile duplex clip can be added after the connectors have been terminated, offering
considerable application flexibility.

Duplex and simplex LC adapters also available in industry standard colors, compliment the connector offering. These
adapters can be provided with either zirconia, ceramic or phosphor bronze sleeves.
