Question

Difficulty: Very hardNetwork and Peripheral Cables and Connectors

Match each network or peripheral cable and connector type on the left with its corresponding technical specification or capability on the right.

  • Cat 6 UTP CableSupports 10GBASE-T Ethernet up to 55 meters with a maximum rated operating frequency of 250 MHz.
  • Molex ConnectorLegacy 4-pin peripheral power connector providing +5 VDC (red) and +12 VDC (yellow) power rails.
  • SC Fiber Optic ConnectorSquare snap-in (push-pull) fiber connector commonly used in enterprise gigabit network infrastructure.
  • USB 3.2 Gen 2x2 CableDelivers up to 20 Gbps throughput by running dual 10 Gbps lanes exclusively over USB Type-C connections.

Answer

Cat 6 UTP Cable matches 10GBASE-T up to 55 meters at 250 MHz; Molex Connector matches 4-pin legacy power (+5V/+12V); SC Fiber Optic Connector matches square push-pull fiber connector; USB 3.2 Gen 2x2 Cable matches 20 Gbps dual-lane throughput over USB Type-C.
The correct matches align each physical cable or connector with its exact electrical, optical, or protocol specifications: Cat 6 UTP supports 10 Gbps up to 55 meters at 250 MHz; Molex provides +5V and +12V power over 4 pins; SC is a square push-pull fiber optic connector; and USB 3.2 Gen 2x2 delivers 20 Gbps dual-lane throughput exclusively over USB Type-C.

Step-by-Step Solution

1
Analyze Ethernet cabling standards and performance envelope
Cat 6 UTP operates at up to 250 MHz and supports 10 Gbps bandwidth up to 55 meters (unlike Cat 6a which supports 100 meters at 500 MHz).
Matching Cat 6 UTP Cable to its specific speed/distance specification.
2
Identify legacy internal power connector specifications
The legacy Molex connector is a 4-pin connector providing +5V (red) and +12V (yellow) DC power to system peripherals.
Differentiating internal power delivery standards.
3
Examine optical fiber connector form factors and latching styles
The SC connector features a square push-pull snap-in body, contrasting with LC (latch) and ST (bayonet twist).
Identifying optical interface physical characteristics.
4
Evaluate USB standard throughput and pin requirements
USB 3.2 Gen 2x2 requires dual-lane signaling supported exclusively by USB Type-C to reach 20 Gbps total bandwidth.
Distinguishing USB signaling throughput and physical form factor requirements.

Key Concept

Identifying network and peripheral cable specifications, physical connector form factors, and signaling capabilities.
