Fiber Optic Cable Facts

What is coaxial cable commonly used for?

To convey data, video, and voice signals in radio, television, and broadband internet applications.

What are the components of coaxial cable?

Inner conductor, insulator, braided mesh conductor, and sheath.

What is the main function of the inner conductor in coaxial cable?

It carries the data signals.

What are the advantages of coaxial cable compared to other types?

Less susceptible to EMI, resistant to physical damage, large existing infrastructure.

What are the disadvantages of coaxial cable compared to other types?

Expensive, not very flexible, multiple splitters degrade signal quality.

What is the resistance rating for RG-59 coaxial cable?

75 ohms.

What type of connector is molded onto the cable and used in Ethernet networks?

BNC connector.

What type of connector is crimped onto the coaxial cable and commonly used for cable TV?

F-Type connector.

What are the two major wiring standards used in the networking industry for twisted pair cables?

T568A and T568B.

What is the composition of twisted pair cabling?

Four pairs of copper wires twisted together.

What are the advantages of twisted pair cable?

Inexpensive, easy to install, flexible, and widely supported.

What is the main disadvantage of twisted pair cable?

It is susceptible to interference.

What type of cable has a speed of 10 Mbps and is used to connect a modem to a phone jack?

Phone cable (RJ11).

What is the maximum speed of Cat 6 twisted pair cable?

10 Gbps for lengths less than 55 meters.

What rating is required for cable installed in plenum spaces?

Plenum rating.

What is the purpose of the cladding in fiber-optic cable?

To maintain the signal in the center of the core.

What are the advantages of fiber-optic cable?

Completely immune to EMI, highly resistant to eavesdropping, fastest transmission rates.

What distinguishes single-mode fiber cables from multi-mode fiber cables?

Single-mode uses a single light ray and supports longer distances, while multi-mode uses multiple light rays and limits distance.

What is an SC connector used for in fiber-optic cabling?

It is a push-on, pull-off connector that uses a locking tab to maintain connection.

What does the abbreviation UTP stand for?

Unshielded Twisted Pair.

What tool is necessary for attaching connectors to twisted pair cables?

A crimping tool.

What must be done to the exposed fiber tip during fiber-optic assembly?

It must be polished to ensure proper core alignment.
