Ethernet Network Cable Types for Hospital Wing Installation

A vendor is installing an Ethernet network in a new hospital wing.

The cabling is primarily run above the celling grid near air conditioning ducts and sprinkler pipes.

Which of the following cable types is required for this installation?

A.

Plenum

B.

PVC

C.

Single-mode

D.

Cat 7

A.

The correct answer is A. Plenum.

The plenum cable is a type of cable specifically designed for use in spaces where air circulates, such as the spaces above the ceiling grid near air conditioning ducts and sprinkler pipes, as mentioned in the question.

In case of a fire, the plenum cable is designed to release less smoke and fewer toxic fumes than other cable types, reducing the risk of damage to the building and minimizing potential harm to people.

On the other hand, PVC (Polyvinyl chloride) cable is a general-purpose cable commonly used in areas where there are no air circulation requirements.

Single-mode cable is a type of fiber-optic cable designed to carry a single beam of light, making it suitable for long-distance transmissions. However, the question specifies the installation of an Ethernet network, which typically uses copper cables.

Cat 7 is a high-speed copper cable designed for use in Ethernet networks, but it is not specifically designed for use in plenum spaces, unlike the plenum cable.

Therefore, based on the location of the cabling and the specific requirements of the environment, the most appropriate cable type for this installation is plenum cable.
