Vszerda USB 4.0 Type-C 10G Ethernet Adapter

SKU CH-36B3-3328M

Adds a 10GbE RJ45 port to USB-C devices, supporting multi-gigabit speeds over standard cabling with passive cooling and Thunderbolt 3/4/5 compatibility

  • Adds 10 Gb/s Ethernet over USB Type-C
  • Supports 5 Gb/s and 2.5 Gb/s on CAT 5e up to 100 m
  • Passive aluminium heatsink runs 0 °C to +108 °C
  • Bus-powered, no external adapter needed
  • Works with Thunderbolt 3/4/5 and MacBook Pro (late 2016)

Portable 10GbE USB-C Adapter

The Vszerda USB 4.0 Type-C 10G Ethernet Adapter adds a single RJ45 port to any computer with a USB Type-C connection. It is built for professionals who need reliable, high-speed wired networking on notebooks like the MacBook Pro (late 2016) or mobile workstations handling I/O demanding applications. The aluminium enclosure provides passive cooling without a fan, drawing all power directly from the host port.

Auto-Negotiation 10G/5G/2.5G Base-T

The Ethernet port auto-negotiates at 10Gb/s, 5Gb/s, 2.5Gb/s, 1Gb/s and 100Mb/s Base-T. Multi-Gigabit speeds of 5 Gb/s and 2.5 Gb/s run over standard CAT 5e cabling up to 100 meters when paired with a compatible switch or router. IEEE 802.1Q VLAN tagging, Energy-Efficient Ethernet, 9K jumbo frames and Wake-on-LAN are all supported.

Plug-and-Play Thunderbolt 3/4/5 Compatible

The adapter works immediately when plugged into any USB Type-C port or at the end of a USB device daisy chain, requiring no external power supply. Full compatibility with Thunderbolt 3, 4 and 5 extends the range of supported hosts. Installers should verify that the operating system recognises the device and that the switch port is configured for the desired NBASE-T speed to avoid negotiation fallback.

Questions about this item

What does the 10Gb/s Ethernet speed actually deliver when the adapter is connected to a real machine?

The adapter provides an RJ45 port that auto-negotiates at 10Gb/s, 5Gb/s, 2.5Gb/s, 1Gb/s or 100Mb/s Base-T, so the real-world throughput matches the switch or router you plug into.

Which USB standard does the Type-C connector use and what does that limit in practice?

It uses USB 4.0 over Type-C and is also compatible with Thunderbolt 3/4/5, so the link speed is capped by the host port's USB or Thunderbolt capability.

What physical space and mounting does the adapter need to fit in my setup?

The aluminum enclosure is passively cooled with ventilation gaps and draws power from the USB connection, so it only needs a free Type-C port and enough clearance for airflow.
