Zorluk: OrtaNetwork and Peripheral Cables and Connectors

A technician is setting up a workstation dock designed to drive dual external 4K monitors and provide 10 Gbps throughput to an external drive enclosure via a single cable connection. The workstation's USB Type-C port is labeled with a lightning bolt symbol indicating Thunderbolt support. However, when using a user-provided USB Type-C cable, the external displays fail to receive a video signal and data transfers fall back to low speeds. Which of the following best explains the primary cause of this issue?

  1. The physical USB Type-C connector does not guarantee protocol capabilities, and using a passive USB 2.0 charging cable omits the high-speed data lanes and DisplayPort Alt Mode wires required for high bandwidth and video output.Cevap
  2. B
    All USB Type-C cables automatically support Thunderbolt 4 standards, indicating that the workstation's integrated graphics processing unit has failed.
  3. C
    The USB Type-C port requires an external T568B pinout patch adapter to route display signals and Ethernet frames across peripheral connections.
  4. D
    Thunderbolt 4 protocol traffic can only be transmitted across dedicated optical fiber patch cables terminated with LC connectors.

Cevap

The physical USB Type-C connector does not guarantee protocol capabilities, and using a passive USB 2.0 charging cable omits the high-speed data lanes and DisplayPort Alt Mode wires required for high bandwidth and video output.
The USB Type-C form factor defines only the physical plug and receptacle interface. Protocol support such as Thunderbolt 3/4, USB 3.2 Gen 2x2, and DisplayPort Alt Mode requires matching host controllers, device support, and appropriately rated cables. Standard USB Type-C charging cables often contain only the minimal wiring for USB 2.0 data (480 Mbps) and power, omitting the high-speed differential pairs required for video Alt Mode signals and multi-gigabit throughput.

Adım Adım Çözüm

1
Differentiate between physical cable form factors and underlying interface protocols.
Recognize that the USB Type-C plug specifies physical pin geometry, whereas protocol standards (USB 2.0, USB 3.2, Thunderbolt, DisplayPort Alt Mode) dictate data transmission capabilities.
Assuming all USB Type-C cables support maximum host capabilities leads to choosing insufficient cables.
2
Analyze the cable requirements for driving dual 4K displays and 10 Gbps storage.
High-bandwidth data and video multiplexing demand high-speed SuperSpeed differential pairs and DisplayPort Alt Mode wiring within the cable.
Basic charging cables only include USB 2.0 D+/D- data lines and power conductors.
3
Identify the cause of the peripheral failure.
The user-provided cable lacks the necessary internal wiring for Thunderbolt/USB 3.2 Gen 2 speed and video transmission.
Replacing the basic charging cable with a fully featured Thunderbolt or USB 3.2 Gen 2 Type-C cable will resolve both display and speed issues.
