Product information

Description

The LMP Thunderbolt 3 cable 21938 is an optical USB-C male-to-male cable with a 25 m length and 40 Gbit/s bi-directional bandwidth. Designed for long-distance connectivity, it carries Thunderbolt 3 signals including PCI Express and DisplayPort (DP Alt Mode) without electrical interference, providing low-latency transfer and accurate time synchronization for professional audio and video workflows. This active optical cable supports daisy-chaining of multiple Thunderbolt devices and operates using USB-C connectors in a 2-lane, full-duplex Thunderbolt 3 configuration. The cable is black and intended for use in studio, AV or workstation environments where high data rate and stable video transmission over distance are required.

Advantages

The optical construction enables consistent 40 Gbit/s throughput across the full 25 m length while avoiding the signal degradation and electromagnetic interference typical of long copper runs. Support for PCI Express and DisplayPort over Thunderbolt 3 ensures compatibility with storage arrays, docks and external GPUs, and the low latency with accurate time synchronization makes it suitable for professional audio and video tasks. The active design allows daisy-chaining of Thunderbolt devices and maintains full-duplex operation.

Suitable for

  • Connecting Thunderbolt-compatible laptops to monitors or docking stations over long distances
  • Linking external storage arrays and RAID enclosures in studio or post-production setups
  • Integrating audio/video interfaces and recorders that require low-latency synchronization
  • Daisy-chaining multiple Thunderbolt 3 devices such as docks, displays and storage

Key specifications

  • Connector type: USB-C (male) to USB-C (male), Thunderbolt 3 compatible
  • Cable type: active optical cable
  • Length: 25 m
  • Maximum data rate: 40 Gbit/s bi-directional
  • Protocol support: Thunderbolt 3, PCI Express, DisplayPort (DP Alt Mode)
  • Operation: 2-lane, full-duplex Thunderbolt 3
  • Typical power consumption: 900 mW at 5 V operation voltage
  • Operating ambient temperature: 0 to 50 °C
  • Does not carry USB data (USB-C USB signals) and does not provide Power Delivery

How to use

Connect each end of the Thunderbolt 3 cable to the USB-C Thunderbolt ports of the source and destination devices. For daisy-chaining, connect from the host to the first device, then continue to subsequent Thunderbolt devices using additional compatible Thunderbolt cables or ports. Ensure connected devices support Thunderbolt 3 and the required protocols (DisplayPort or PCIe) for your use case. Operate the cable within the specified ambient temperature range and provide appropriate ventilation for connected hardware. No special drivers are required for basic Thunderbolt 3 functionality beyond the host device's standard Thunderbolt support.

Usage recommendations

Use the cable only with Thunderbolt 3‑capable USB‑C ports; avoid relying on it for USB-only devices or for charging since it does not transmit USB data or Power Delivery. Route the cable to avoid tight bends and sharp kinks, keep it away from strong heat sources, and verify device compatibility for DisplayPort and PCIe features before deployment in professional AV or storage systems.
