Discussion Overview
The discussion revolves around the potential electrical interference on data cables (USB, Ethernet, HDMI) placed in a shared conduit over a distance of approximately 8 meters. Participants explore concerns related to cable shielding, length limitations, and the implications of using different types of cables.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant questions whether the proximity of the USB, Ethernet, and HDMI cables could cause interference, given that only the USB cable carries a low voltage.
- Another participant notes that the cables are likely individually shielded and references the USB 3.0 standard's lack of a specified maximum cable length, suggesting that sourcing longer cables may be problematic.
- A later reply mentions the existence of "Active USB extension cables" that can extend the length beyond typical limits, indicating a preference for USB 2.0 due to sufficient speed for the user's needs.
- One participant highlights the maximum length for USB 2.0 and provides information on available boosted cables, suggesting practical options for the user.
- Another participant raises concerns about potential issues with long HDMI cables, recommending the use of a single cable without additional connectors if possible.
Areas of Agreement / Disagreement
Participants express varying opinions on the feasibility of using longer cables and the potential for interference. There is no consensus on the best approach to mitigate interference or the optimal cable type for the setup.
Contextual Notes
Limitations include the lack of definitive specifications for cable lengths and performance, as well as the dependence on specific equipment and screen resolutions for HDMI performance.
