Frequently Asked Questions
What is the maximum length available for this Thunderbolt 3 cable?
For passive cables to achieve the full 40Gbps bandwidth, the standard maximum length is 0.8 meters (2.6 ft). For longer lengths (up to 2 meters), we offer active Thunderbolt 3 cables with built-in signal boosters.
Is this cable backward compatible with standard USB-C devices?
Yes, it is fully backward compatible with USB 3.2, USB 3.1, and USB 2.0 devices. However, the data transfer speed will match the capability of the connected USB standard (e.g., 10Gbps or 5Gbps).
Does the cable support 100W charging safely?
Absolutely. Our Thunderbolt 3 cables feature integrated E-Marker chips that intelligently negotiate power delivery, safely supporting up to 100W (20V/5A) for laptops and high-power equipment.
Can EDOM Electronics print our company logo on the connector?
Yes, we provide full OEM/ODM services, including custom laser engraving of your logo on the aluminum connector shell, custom overmold designs, and tailored packaging.
