Network Cabling and Connectors

Correct Answer: Multimode

The correct answer is Multimode. Multimode fiber optic cable has a larger core diameter, which allows multiple modes (paths) of light to propagate, thus 'multimode'. When it comes to data transfer over short distances, up to 2km, such as in data centers or LANs, this type of cable is typically used. Comparatively, the other choices are different types of cables, but they are not fiber optic cables. STP (Shielded Twisted Pair) and UTP (Unshielded Twisted Pair) are both types of copper Ethernet cables used in networking. Coaxial cable, also made of copper, is heavily shielded and used for cable internet connections and cable television.

Correct Answer: RJ45 connector

The RJ45 connector is the correct answer because it is the standard connector type used for Ethernet cabling in local area networks. It is used in wired networks to connect devices such as computers, routers, and switches using Ethernet cables. The other options, LC, ST, and SC connectors, are types of fiber optic connectors, which are used in fiber optic cabling, not Ethernet cabling.

Correct Answer: Fiber optic

Fiber optic cable is the best choice for outdoor network installations. This is primarily due to its ability to transmit data over long distances without loss of signal quality, which makes it ideal for outdoor and large installations. Fiber optic cables are also immune to electrical interference, unlike UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) cables. These properties make fiber optic a superior choice for outdoor installations. Coaxial cable, while capable of transmitting data over long distances, is not typically used in contemporary outdoor network installations due to its susceptibility to signal degradation and interference over long distances.
