Straight Tip
Snap & Twist

• Bayonet Connector, untwist/pull.

• 2.5mm

• Looks similar to SC except SC has no threading, it's a twist/locking type of mechanism.

Local Connector
Little Connector

• 2 fibers cables in a single connector

• High density fiber designed by Lucent to be used in fiber optic networks.

• snap connector

• 1.25mm (It's thiner, smaller than the others hence why it's known as Little Connector)

• often confused with SC (Square Connector) due to it also being cased in a square connector, but be sure to notice the big difference in size. SC = 2.5mm where LC = 1.25mm.

• smaller than the typical SC connector

• snap connector

• 2 fibers

Subscriber Connector
Square Connector
Stick & Click

• square connector with a spring loaded coupling to improve performance.

• 2.5mm

• usually in a square casing hence "square connector"

• snap/push-pull

Fiber Channel

• Screw On: looks very similar to ST (straight tip/screw-twist) with a bayonet, but the difference with SC is you will see Threading to Screw it On.

• 2.5mm

Small, 2 tiny fibers at the end

| Similar to an LC with a Locking Mechanism
