Fiber Optic Facts

Question 1

Fiber Optic

Answer 1

• Two fiber strands to connect computers together

* One strand transmits signals the other receives signals

Question 2

Fiber Optic is composed of what components?

Answer 2

• A plastic or glass core that carries the signal
• A cladding surround the core that maintains the signal as the cable bends
• A sheath that protects the cladding and the core

Question 3

Fiber Optic Advantages

Answer 3

• Completely immune to EMI
• Highly resistant to eavesdropping
• Supports extremely high data transmission rates
• Allows greater cable distances without a repeater

Question 4

Fiber Optic Disadvantages

Answer 4

• Expensive
• Difficult to work with
• Special training required to connect connectors to the cable

Question 5

Single-mode

Answer 5

• Transfer data through the core using a single light ray (mode)
• Supports large amount of data
• Core diameter is around 10 microns
• Cable lengths can extend to a great distance

Question 6

Multi-mode

Answer 6

• Transfers data through the core using multiple light rays
• Core diameter is around 50 to 100 microns
• Cable lengths are limited in distance

Question 7

ST Connector

Answer 7

• Used with single mode and multi-mode cabling
• Keyed, bayonet-type connector
• AKA push-in connector or a twist connector
• Each wire has a separate connector
• Nickel plated with a ceramic ferrule to ensure proper alignment and prevent light ray deflection
• Necessary to polish the exposed fiber tip to ensure that light is passed on form one cable to the next with no dispersion

Question 8

SC Connector

Answer 8

• Used with single mode and multi-mode cabling
• Push on. pull off connector type that uses a locking tab to maintain connection
• Each wire has a separate connector
• Uses a ceramic ferrule to ensure proper core alignment and prevent light ray deflection
• Necessary to polish the exposed fiber tip

Question 9

LC Connector

Answer 9

• Used with single mode and multi-mode cabling
• Composed of a plastic connector with a locking tab, similar to an RJ-45 connector
• Single connector with two ends keeps the cables in place
• Uses a ceramic ferrule to ensure proper core alignment and prevent light ray deflection
• Half the size of other fiber optic connectors

Question 10

MT-RJ Connector

Answer 10

• Used with single mode and multi-mode cabling
• Composed of plastic connector with a locking tab
• Uses metal guide pins to ensure it is properly aligned
• Uses a ceramic ferrule to ensure proper core alignment and prevent light ray deflection
