Sumitomo Electric Launches Thunderbolt™ 3 Cables on Amazon Japan

Sumitomo Electric Industries, Ltd. launched its Thunderbolt™ 3 cables capable of40 Gbps transmission on Amazon.co.jp on November 20, 2019.
Thunderbolt™ is a fast general-purpose data transmission specification developed byIntel Corporation for data communications between a personal computer and peripheraldevices such as a display.*1 Sumitomo Electric undertook the development ofThunderbolt™ cables based on technical specifications disclosed by Intel to Sumitomo
Electric. In 2010, Sumitomo Electric acquired the world’s first Thunderbolt™
certification and in November 2015 obtained another certification for Thunderbolt™ 3cables that enable 40 Gbps transmission. Since then, Sumitomo Electric has been
selling Thunderbolt™ 3 cables as a major vendor of the product.
In recent years, along with the increasing instances of handling large data such as
high-resolution video data, made possible by the improved performance of personal
computers and peripherals, there has been growing demand for higher-ratetransmission. Moreover, since the number of Thunderbolt™-compatible peripherals has
been growing, Sumitomo Electric has decided to sell its Thunderbolt™ 3 cables onAmazon.co.jp to make the product available to a larger number of users.
To guarantee ease of use, all Thunderbolt™ 3 products are obliged to pass acertification test. Certified Thunderbolt™ 3 cables have been tested and meet thefollowing features and specifications.

1. Features(1) Ultrafast transmission up to 40 Gbps
Thunderbolt™ 3 cables enable high-speed transmission
between Thunderbolt™ 3-compatible devices such asmultiple 4K displays, external graphics boards, external
high-capacity data storage (e.g. HDD, SDD) and fast
gaming PCs. The cables operate at a transmission rateeight times higher than that of USB 3.0 cables currently
in wide use.
(2) Maximum power delivery of 100 W
Each Thunderbolt™ 3 cable can supply power up to 100
W (5 A at 20 V) (c.f. USB 3.0: 4.5 W). It provides stable
power, eliminating the need to provide a power supply to peripherals that consume
high power.
(3) Flexible and flex-resistant
Sumitomo Electric’s proprietary micro-coaxial cable technology is used to make thecables highly flexible and flex-resistant. The cables are highly durable even ifpinched up to 180 degrees or tangled in knots.
