In 10GBASE-T networks, Category 6 (Cat 6) UTP cabling supports a 10 Gbps data transfer rate at a limited range of 33-55 meters, whereas Cat 6a (augmented) cabling allows for 10 Gbps data transfer rate over a cable segment length of 100 meters.
True or False?
True
Category 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. Category 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.
True or False?
True

In modern Ethernet networks, a twisted-pair copper cable terminated according to the TIA/EIA-568A standard on one end and TIA/EIA-568B standard on the opposite end forms a:
Crossover cable
Straight-through cable
Patch cable
None of the above
None of the above
Mixing the wiring standards will cross over pairs 1-2 and 3-6 and leave 4-5 and 7-8 straight through. This wrong connection is something like a half-crossover cable.
With older Ethernet standards 100BASE-TX or 10BASE-T, which use only two of the pairs, this would work as a crossover cable.
For 1000BASE-T, which uses all pairs, this is simply wrong wiring.
A correct crossover cable has both pairs 1-2 and 3-6 and pairs 4-5 and 7-8 crossed. This will work with old and new Ethernet standards.

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 angle, which results in better performance.
True or False?
True
