Zorluk: OrtaNetwork Cable Types and Connectors

A network technician is preparing to run Ethernet cabling through an HVAC plenum space above ceiling tiles to connect a high-performance server. The connection must support 10 Gbps throughput at a distance of 85 meters while adhering to strict building fire safety regulations. Which of the following cabling standards and jacket ratings should the technician select? (Select TWO.)

  1. Category 6a (Cat 6a) cablingCevap
  2. CMP (Plenum-rated) jacketCevap
  3. C
    Category 5e (Cat 5e) cabling
  4. D
    CMR (Riser-rated) jacket

Cevap

The technician must select Category 6a (Cat 6a) cabling and a CMP (Plenum-rated) jacket.
Category 6a (Cat 6a) provides 10 Gbps bandwidth up to the full 100-meter standard distance, satisfying the 85-meter requirement. Additionally, CMP (Plenum-rated) cabling is coated with fire-retardant materials that emit minimal toxic smoke, fulfilling environmental air space safety regulations.

Adım Adım Çözüm

1
Determine the required cable category for bandwidth and distance
Cat 6a supports 10 Gbps up to 100 meters, whereas standard Cat 6 is limited to 55 meters for 10 Gbps speeds and Cat 5e maxes out at 1 Gbps.
The scenario requires 10 Gbps throughput across an 85-meter span.
2
Determine the necessary cable fire safety rating
CMP (Communications Multipurpose Cable, Plenum) is required for air-handling plenum spaces.
Plenum spaces circulate environmental air; burning non-plenum cable releases dangerous toxic fumes into the ventilation system.
