Fiber Connector - ST?

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.

Fiber Connector - LC?

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.

Fiber Connector - MTRJ?

- smaller than the typical SC connector - snap connector - 2 fibers

Fiber Connectors - SC?

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 Connector - FC?

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

Fiber Connector - RT-RJ?

Small, 2 tiny fibers at the end | Similar to an LC with a Locking Mechanism

Fiber: Short Range?

Multimode Up to 2km Uses LED's Less Expensive

Fiber: Long Range?

Singlemode 100 km Lasers Very expensive
