The Sonnet Thunderbolt 3 Male to Dual DisplayPort 1.2 Female Adapter utilizes the reversible USB Type-C connector to support a maximum throughput of 40 Gb/s when used with compatible devices. The connector also transmits data via USB 3.1 at up to 10 Gb/s, and the dual-bandwidth DisplayPort 1.2 outputs allow you to connect up to two 4K displays simultaneously or a single 5K display at 60 Hz.
Please note that not all Windows and Mac computers with Thunderbolt 3 support dual displays or 60 Hz refresh rates. You'll have to check the official Sonnet website for more details. Also, connecting to a single 5K display requires the use of both DisplayPort outputs on the adapter.
