Normalisation is the process of structuring a database to reduce redundancy and improve data integrity. It involves organizing data into tables that meet specific rules—starting with First Normal Form (1NF) and Second Normal Form (2NF)—to ensure each field depends fully on the primary key and that data is stored efficiently.

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
