Question

What are the maxiμm allowable distances for horizontal wiring for a span connecting a data jack on a wall to a data closet and for a span connecting a workstation to the data jack, respectively?

a) 90 meters, 5 meters
b) 100 meters, 10 meters
c) 70 meters, 15 meters
d) 120 meters, 20 meters

Answer 1

The maximum allowable distances for horizontal wiring are 90 meters from a data jack to a data closet and 5 meters from a workstation to the data jack.

Step-by-step explanation:

The maximum allowable distances for horizontal wiring are regulated to maintain the integrity of data transmission. The correct distances The maximum allowable distances for horizontal wiring are 90 meters from a data jack to a data closet and 5 meters from a workstation to the data jack.

These limits ensure that the signal strength is maintained without significant loss over the copper cabling usually used for such installations, known as Category 5e or Category 6 cabling. The maximum allowable distances for horizontal wiring are 90 meters from a data jack to a data closet and 5 meters from a workstation to the data jack. Typically, this cabling standard follows the TIA/EIA-568 industry specifications.
