1
Q

The general feature of all twisted-pair cabling types is that wires inside the cable are grouped into pairs and wires in each pair are twisted around each other to reduce signal interference from adjacent wire pairs (effect known as crosstalk).

Q

Cat 7 is a twisted-pair cabling standard featuring improved specifications for canceling crosstalk and system noise. As in Cat 6a, Cat 7 cabling offers 10 Gbps data transfer rate over a cable segment length of 100 meters in 10GBASE-T networks. Cat 7 standard introduces new connector types (the GG45 and TERA connector). Cat 7 cabling has not seen a widespread consumer market adoption yet, because all manufacturers of active equipment and network cards prefer Cat 6a standard which offers similar performance and takes advantage of the traditional RJ45 connector.

More expensive than multimode fiber optics
Transmission distances of up to 100 km
Uses laser as the source of light

17
Q

Which of the answers listed below refer to the characteristic of multimode fiber optics? (Select 3 answers)

A

Transmission distances of up to 2 km.
Less expensive than single-mode fiber optics.
Uses LED as the source of light.

19
Q

The shape and angle of the tip of a fiber-optic connector can have an impact on the performance of a fiber-optic communication link. The two basic types of fiber end are Ultra Physical Contact (UPC) and Angled Physical Contact )APC). In the UPC-type connector, the connector end is polished with no angle, while APC connectors feature a fiber end polished at an 8-degree angel, which results in better performance.
