2 Physical Network Installation and Cabling Free Online FlashCards

What should a site survey check before cable is pulled?

Survey device locations and cable routes, checking pathway capacity, access, obstacles, support points, and space for service loops.

What ladder precautions help reduce electrical hazards?

Inspect ladders before use, use them as intended, and avoid metal ladders near power lines or exposed energized equipment.

How should communications cabling be routed near electrical interference sources?

Keep communications cabling separated from electrical interference sources as required by applicable standards and installation instructions.

How should T568A and T568B be used on a straight-through link?

Use the same scheme, either T568A or T568B, at both ends of a normal straight-through link.

Why should twisted-pair conductors remain twisted close to the termination?

Keep pair twists as close as practical to the termination; excessive untwisting can degrade link performance.

What does a category-rated punch-down tool do?

A category-rated punch-down tool seats conductors in insulation-displacement contacts (IDCs) and trims excess wire.

When is fiber cabling especially useful?

Fiber carries data as light and is useful for high-bandwidth links, longer runs, or routes where electrical interference is a concern.

What should be done to fiber connector end faces before mating?

Inspect, clean, and inspect connector end faces before mating them; contamination can increase loss or damage the end faces.

Why must you never look into a fiber end?

Never look into a fiber end: invisible laser light may be hazardous.

How should installed network links be labeled?

Label both ends of every link with matching, unique identifiers, and label ports, outlets, and pathways consistently.

What can a basic copper verifier check?

A basic copper verifier can check wire map, continuity, shorts, and miswires.

What do permanent-link and channel tests cover, and what are their length limits?

A permanent-link test covers fixed cabling, not equipment patch cords. Structured-cabling limits are up to $90\ \text{m}$ for a permanent link and $100\ \text{m}$ for a channel.
