LMP Thunderbolt 3 Cable, active

Thunderbolt 3 (USB-C) Cable, active, 40 Gbit/s, 4K/5K, 60W, black


product overview

The LMP Thunderbolt 3 cable (active) provides data transfer rates of up 40 Gbps with clock & data recovery chip inside. It takes full advantage of the Thunderbolt technology by supporting 2-channel Thunderbolt Gen 2 and Thunderbolt Gen 3 full duplex high speed transmission. It is also capable of 1-channel USB 2.0 transmission (but it does not support USB-C Gen 1 or Gen 2 transmission nor does it support DP Altmode (video) transmission via USB-C). Furthermore, the active LMP Thunderbolt 3 cables are capable of dual-protocol support for Thunderbolt mode (PCIe and DP [note: DP Altmode via USB-C Gen 1 or Gen 2 is not supported!]*) so the active cables can be used for daisy-chaining devices. A maximum current of 60W (max. 5A) according to Power Delivery 2.0 specifications can be transmitted.

*If you have an external monitor which has a USB-C input port, you may use the LMP passive Thunderbolt 3 cables (P/N 19015, 16598 or 16599) or a USB-C cable (P/N 17757) since an active Thunderbolt 3 cable does not support the DP Altmode (video) via USB-C.
If you have an external Thunderbolt 3 monitor, you can use either an active or passive Thunderbolt 3 cable (while a USB-C cable will not work).

The Thunderbolt cable let’s you connect a broad variety of external devices such as storage enclosures or RAID systems with up to 40 Gbps data transfer, displays (2x 4K monitors and a single 5K monitor), docking stations or power supplies with up to 60W and a host power output of up to 15W to attached Thunderbolt/USB-C devices (based on USB Power Delivery rules). It’s the most universal cable for the most advanced I/O technology. The plug is reversible and it works with any Thunderbolt 3 enabled device with physical USB-C port.

The Thunderbolt 3 enabled computer features a USB-C port with a Thunderbolt icon (lightning bolt next to the port). You should consult your computer’s tech specs to make sure that it is fully Thunderbolt 3 compatible.

FAQ & Support

When I connect an external M.2 NVMe PCI SSD drive with a Thunderbolt 3 cable, the transfer rate is only about 35 MB/s (like USB 2.0). Why?
