Zorluk: OrtaNetwork and Peripheral Cables and Connectors

A network technician is installing a new copper Ethernet run to connect a desktop computer to a distribution switch located 90 meters (295 feet) away. The network specification requires guaranteed 10 Gbps data throughput over the full distance of the unshielded twisted-pair (UTP) cable run. Which of the following cable standards is the MINIMUM requirement to meet this objective?

  1. Category 6a (Cat 6a)Cevap
  2. B
    Category 6 (Cat 6)
  3. C
    Category 5e (Cat 5e)
  4. D
    Category 5 (Cat 5)

Cevap

Category 6a (Cat 6a) is the correct answer as it is the minimum cable standard rated to support 10 Gbps network throughput over a full 100-meter distance.
Category 6a (Augmented Category 6) cabling is designed with higher frequency specifications (up to 500 MHz) and enhanced crosstalk mitigation, enabling it to deliver 10 Gbps speeds over the maximum standard copper run length of 100 meters (328 feet). Since the run is 90 meters, Category 6a is the minimum requirement.

Adım Adım Çözüm

1
Identify the distance and bandwidth constraints from the scenario.
The requirement specifies 10 Gbps throughput across a distance of 90 meters (295 feet).
Ethernet cable performance ratings depend on both data frequency/throughput limits and physical distance bounds.
2
Evaluate candidate copper twisted-pair cable standards against the requirements.
Cat 5e maxes out at 1 Gbps. Cat 6 supports 10 Gbps up to only 37 to 55 meters. Cat 6a supports 10 Gbps up to the full 100-meter (328-foot) limit.
Cat 6a operates at 500 MHz frequencies and incorporates tighter twisting to prevent crosstalk over longer distances.
3
Select the minimum standard that satisfies both distance and bandwidth criteria.
Category 6a (Cat 6a) meets the 10 Gbps requirement at 90 meters.
It fulfills all specifications without requiring fiber optic media or higher unnecessary cabling classes.
