Question

Difficulty: MediumNetwork Cable Types and Connectors

Match each network cabling standard or connector type to its corresponding operational characteristic and primary deployment scenario.

  • Category 6 (Cat 6) CableSupports 10 Gbps speeds up to 55 meters over unshielded twisted-pair copper cabling in standard enterprise deployments.
  • Multi-Mode Fiber (MMF)Utilizes a relatively wide core diameter and light-emitting diode (LED) or VCSEL sources for short-to-medium distance backbones within buildings.
  • Single-Mode Fiber (SMF)Utilizes a narrow core diameter with a laser diode light source to transmit data over long distances up to tens of kilometers.
  • RG-6 Coaxial CableFeatures a heavy 18 AWG copper center conductor surrounded by dielectric insulation and shielding, commonly terminated with F-type connectors.

Answer

Category 6 (Cat 6) Cable matches 10 Gbps speeds up to 55 meters. Multi-Mode Fiber (MMF) matches wider core diameter with LED/VCSEL light sources for short-to-medium distances. Single-Mode Fiber (SMF) matches narrow core diameter with laser diodes for long distances up to tens of kilometers. RG-6 Coaxial Cable matches 18 AWG center conductor with F-type connectors for cable TV and broadband.
Each cabling type is matched to its core physical and technical specification defined under standard networking guidelines: Cat 6 delivers 10 Gbps up to 55m; MMF uses a wide core with LED/VCSEL light for building backbones; SMF uses a narrow 9-micron core with laser diodes for long-distance link spans; RG-6 utilizes an 18 AWG wire terminated with F-type connectors for broadband signal delivery.

Step-by-Step Solution

1
Analyze copper twisted-pair specifications
Category 6 cable supports standard 1 Gbps up to 100 meters, but can achieve 10 Gbps up to a limited distance of 55 meters.
CompTIA A+ objectives specifically test distance limits for 10GBASE-T over Cat 6 vs Cat 6a.
2
Differentiate Multi-Mode Fiber (MMF) from Single-Mode Fiber (SMF)
MMF has a wider core for multiple light paths (LED/VCSEL light source, shorter distance), while SMF has a narrow core for a single light path (laser source, multi-kilometer distance).
Modal dispersion limits MMF to shorter runs, whereas SMF eliminates modal dispersion for long-haul carrier networks.
3
Identify coaxial cable construction and applications
RG-6 uses an 18 AWG wire and F-type connectors for broadband cable internet and satellite drops.
RG-6 replaced thinner RG-59 due to superior shielding and lower signal loss at higher frequencies.
