Which statement about LC connectors is true according to the notes?

• A. LC connectors are high loss and large form
• B. LC connectors are low loss and small form
• C. LC connectors are used only for multimode fiber
• D. LC connectors are not keyed

Answer: (B)

LC connectors are designed to be a small form factor while offering low insertion loss, making them ideal for high-density fiber deployments. The small 1.25 mm ferrule and duplex housing let more connections fit in a given space, and the precision alignment surfaces contribute to keeping the signal loss minimal. They also include a keyed, push‑pull latch design to prevent incorrect mating, so they aren’t used without proper orientation or locking. That’s why the statement describing them as low loss and small form is the true one. The other descriptions conflict with their real characteristics: they are not high loss or large, they aren’t limited to multimode fiber, and they are indeed keyed.
