Fiber Optic cabling

Question

Answer

What does fiber optic cable use to transmit information?

Light instead of electrical signals

Is fiber optic immune to EMI and RFI?

Yes

Why is fiber optic more secure than copper?

It is difficult to tap without specialized equipment

How does fiber signal degradation compare to copper over distance?

Signals degrade less

Where is fiber optic ideal for use?

Environments with industrial equipment or high interference

What does fiber optic installation require?

Specialized equipment for installation

What is the core of a fiber optic cable?

A high-refractive-index material where light travels

What is the cladding in a fiber optic cable?

A low-refractive-index layer that reflects light back into the core via total internal reflection

What is the buffer coating in a fiber optic cable?

A protective layer shielding the core and cladding from physical damage

What light source is commonly used for short-range transmissions?

LED

What light source is used for long-range transmissions?

Laser

What is a ferrule?

A ceramic component at the connector's center that holds and aligns the fiber

How is a ferrule identified visually?

As a small discoloration in the center of the connector

What do fiber optic connectors ensure?

Protection of the fragile fiber core and precise alignment

What does MMF stand for?

Multimode Fiber

What is MMF used for?

Short-range communication

What is the typical maximum distance for MMF?

Up to 2 kilometers

What light source does MMF use and why?

LED

Why does MMF have signal dispersion over long distances?

Its larger core diameter allows light to travel in multiple paths (modes)

What does SMF stand for?

Single-Mode Fiber

What is SMF designed for?

Long-range communication

What light source does SMF use?

Laser

Why does SMF have less signal loss and dispersion?

Its narrow core diameter ensures light travels in a single path (mode)

What factors determine which fiber type and connector to choose?

Distance

What does fiber optic installation and maintenance require?

Specialized tools and training

How does fiber optic cost compare to copper?

More expensive
