Lightware CAB-USBC-T400B 4m USB Full-Featured Type-C cable for USB 3.1 Gen1 & 4K60 Video Microcoax technology - 13740023

Product Overview

The Lightware CAB-USBC-T400B is a 4-meter Full-Featured USB-C cable using Microcoax internal construction. It supports USB 3.1 Gen1 data, 4K/60Hz DisplayPort Alternate Mode video, and Power Delivery — all over a single USB-C connector, at a length that exceeds the reliable range of standard passive copper USB-C cables. Designed for Lightware UCX BYOD AV deployments. Available from Creation Networks at creationnetworks.net.

Product Description

At 4 meters, the CAB-USBC-T400B covers the most common conference table cable run: from a centrally positioned desk pop-up or cable outlet to a laptop at the far end of a medium-sized table. The Microcoax construction maintains the signal integrity of USB 3.1 and DP Alt Mode over this distance without requiring active electronics — keeping the cable passive, reliable, and free from chipset compatibility concerns.

The 4m length is the preferred specification for most standard conference room deployments. Where longer runs are required, the 5m CAB-USBC-T500B covers the next step. Selecting the correct length avoids excess cable at the table surface and reduces the clutter that undermines the clean aesthetic of managed BYOD rooms.

Frequently Asked Questions

What makes this different from a standard 4m USB-C cable bought from a consumer electronics store?

Standard passive USB-C cables at 4 meters use twisted-pair conductors that cannot reliably carry USB 3.1 SuperSpeed or DisplayPort Alt Mode signals. The CAB-USBC-T400B uses Microcoax conductors, which have lower signal loss at extended lengths and maintain the impedance characteristics needed for 5 Gbps USB and 4K60 DP Alt Mode.

Does this cable require any drivers or configuration?

No. It is a passive cable. Plug it in and the host and device negotiate the connection automatically via the USB-C CC pins.

When should I choose the 4m cable over the 5m CAB-USBC-T500B?

Choose the 4m cable when the distance from the desk outlet or pop-up to the UCX receiver is 4 meters or less. Excess cable at the table surface increases clutter and management complexity. Use the shortest length that covers the actual run.

Does this support Thunderbolt?

No. The CAB-USBC-T400B supports USB 3.1 Gen1 (5 Gbps) and DisplayPort Alt Mode. It does not support Thunderbolt 3 or Thunderbolt 4.

Can laptops without DP Alt Mode use this cable?

Yes for USB data and Power Delivery. Video will not work if the laptop's USB-C port does not support DisplayPort Alternate Mode.

Is there a shorter version for conference tables with smaller footprints?

The Lightware UCX cable range includes multiple lengths. Contact Creation Networks at creationnetworks.net to identify the correct length for your specific table and room layout.
