Corning

Corning Thunderbolt 3 Optical Cable 10m

SKU CH-RFTV-WBG76

A 10 m Thunderbolt optical cable linking devices at up to 40 Gb/s over 32.8 ft with galvanic isolation and thermal shutdown

  • Transfers data at up to 40 Gb/s over 10 m
  • Optical design reaches 32.8 ft without signal loss
  • All-dielectric construction gives enhanced galvanic isolation
  • Durable, abrasion-resistant build withstands daily handling
  • Automatic thermal shutdown protects components from overheating

Thunderbolt 3 Optical Cable 10m

This Corning cable connects Thunderbolt 3 devices over a 10 metre distance using male-to-male USB Type-C connectors. Its optical construction allows high-speed data transfer up to 40 Gb/s across greater ranges than copper alternatives. The all-dielectric design provides enhanced galvanic isolation against electrical interference. It is built for daisy-chaining self-powered Thunderbolt 3 displays and peripherals with macOS systems.

Sustained-load behaviour

The cable incorporates an automatic thermal shutdown feature that protects internal components from damage during prolonged exposure to high temperatures. Its durable, abrasion-resistant construction is designed to withstand the physical demands of permanent installations. Optical signalling maintains signal integrity over the full 10 metre length without the degradation typical of copper at this distance. Galvanic isolation continues to shield data from ground-loop noise throughout extended sessions.

Deciding specification

The single specification that determines suitability is the 10 metre reach combined with 40 Gb/s Thunderbolt 3 throughput. Buyers who need longer runs than copper allows but cannot accept lower bandwidth will find this cable matches both requirements. Buyers who require shorter passive cables or who do not have Thunderbolt 3 ports on both ends cannot use this product.

Questions about this item

Does the 10 m optical cable generate heat or noise during continuous use?

The cable uses an all-dielectric optical design with no active electronics, so it produces no heat or noise even when running all day. An automatic thermal shutdown protects internal components if ambient temperatures become extreme.

What Thunderbolt 3 devices must I already own to use this cable?

You need two Thunderbolt 3 hosts or peripherals with USB Type-C ports — for example a Mac and a self-powered 4K or 5K display — to connect with the male-to-male connectors.

Will the 40 Gb/s link work reliably with older Thunderbolt 2 gear I keep?

This cable is built for Thunderbolt 3 USB Type-C connections only; it does not carry Thunderbolt 2 signals or mate with Mini DisplayPort connectors.
