Difficulty: HardNetwork and Peripheral Cables and Connectors

A network technician is auditing legacy and modern cabling infrastructure in an enterprise deployment. Match each cable or connector type on the left with its correct physical characteristic or performance specification on the right.

  • RG-6 Coaxial CableFeatures a 75-ohm impedance rated for broadband cable modems and satellite signals using threaded F-type connectors.
  • Cat 6a UTP CableSupports 10 Gbps Ethernet throughput operating at frequencies up to 500 MHz across a full 100-meter channel.
  • Single-Mode Fiber CableUtilizes a narrow ~9-micron core with laser transmitters for long-haul WAN connectivity up to 40 kilometers.
  • eSATA CableProvides up to 6 Gbps direct external drive bus connectivity with a maximum length limitation of 2 meters.

Answer

RG-6 Coaxial Cable matches 75-ohm broadband/F-type connectors; Cat 6a UTP Cable matches 10 Gbps at 500 MHz up to 100m; Single-Mode Fiber Cable matches narrow core laser transmission up to 40 km; eSATA Cable matches 6 Gbps external drive connectivity limited to 2 meters.
Each cable type aligns precisely with its engineering specification: RG-6 operates at 75-ohm impedance with F-type connectors; Cat 6a provides 10 Gbps bandwidth at 500 MHz up to 100m; Single-Mode Fiber uses lasers across a 9-micron core for distances up to 40 km; eSATA offers 6 Gbps external storage connections with a 2-meter maximum length.

Step-by-Step Solution

1
Identify the RF broadband media characteristics.
Connect RG-6 coaxial cable to 75-ohm impedance, F-type threaded connectors, and cable modem applications.
RG-6 is engineered specifically with 75-ohm characteristic impedance and thick shielding for cable internet and TV signals.
2
Evaluate high-speed Ethernet copper cabling standards.
Associate Category 6a (Cat 6a) with 500 MHz frequency rating and 10 Gbps throughput over 100 meters.
Standard Cat 6 is limited to 37–55 meters for 10 Gbps, whereas Cat 6a reduces crosstalk to maintain 10 Gbps over the full 100m distance.
3
Analyze optical fiber transmission modes.
Associate Single-Mode Fiber (SMF) with a narrow glass core (~9 μm), laser illumination, and long-range limits (up to 40 km).
Multi-mode fiber uses LED light sources and larger cores (~50–62.5 μm) for shorter distances, while single-mode uses focused lasers for long-haul WAN links.
4
Determine external peripheral storage bus limits.
Match eSATA with 6 Gbps raw transfer speed and a strict 2-meter physical distance limit.
eSATA maintains native SATA controller speeds to external drives without conversion overhead, but strict signal attenuation caps its maximum cable length at 2 meters.
