A

OW > O > GW > BL > BLW > G > BNW > B

Just remember your Oranges are in slots 1 and 2.

34
Q

Fiber Connector - ST?

A

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.
35
Q

Fiber Connector - LC?

A

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.
36
Q

Fiber Connector - MTRJ?

A
  • smaller than the typical SC connector
  • snap connector
  • 2 fibers
37
Q

Fiber Connectors - SC?

A

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
38
Q

Fiber Connector - FC?

A

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
39
Q

Fiber Connector - RT-RJ?

A

Small, 2 tiny fibers at the end

Similar to an LC with a Locking Mechanism

40
Q

Fiber: Short Range?

A
