Home Networking Network Adapter StarTech.com TB310G2 Thunderbolt 3 to 10GbE RJ45 Network Adapter

StarTech.com TB310G2 Thunderbolt 3 to 10GbE RJ45 Network Adapter

Brand:
StarTech.com

The StarTech.com TB310G2 is a portable single-port Thunderbolt 3 to 10GbE Ethernet adapter that adds high-speed RJ45 networking to Thunderbolt 3/4 computers. Powered by the Marvell AQC107S chipset, it supports automatic negotiation at 10Gbps, 5Gbps, 2.5Gbps, 1Gbps and 100Mbps, making it suitable for high-performance storage, server administration, media workflows and bandwidth-intensive business applications. The aluminum, fanless design provides quiet operation, while the included 70cm certified Thunderbolt 3 cable simplifies deployment.

OVERVIEW

  • The TB310G2 is a single-port Thunderbolt 3 to RJ45 10GbE adapter for adding high-speed wired networking to compatible laptops, desktops and workstations. Compatibility: Thunderbolt 3/4 hosts; Windows and macOS; 10/5/2.5/1Gbps and 100Mbps Ethernet networks. Compared with basic USB Ethernet adapters: Thunderbolt connectivity enables up to 10GbE, while the fanless aluminum enclosure supports quiet portable deployment. It is particularly suited to high-throughput storage, server maintenance and professional workflows.

USE CASES

  • 10GbE workstation upgrades: Add 10Gbps RJ45 networking to Thunderbolt-enabled laptops and desktops without installing an internal PCIe NIC.
  • High-performance network storage: Connect compatible workstations to 10GbE NAS or storage infrastructure for faster large-file transfers and collaborative workflows.
  • Server administration: Provide a portable wired high-speed network interface for IT professionals managing compatible network environments.
  • Video and media production: Increase available wired bandwidth for large media files, shared storage and demanding production workflows.
  • Data-intensive professional workstations: Support high-throughput connectivity for engineering, design, scientific and other bandwidth-intensive applications.
  • Mobile IT deployments: Use the compact external form factor when users need enterprise-class wired connectivity across different work locations.
  • Network migration projects: Take advantage of automatic speed negotiation when connecting newer 10GbE infrastructure to existing 5GbE, 2.5GbE, 1GbE or 100Mbps networks.
  • Remote and hybrid workstations: Give Thunderbolt-enabled business laptops a dedicated wired connection where Wi-Fi performance or reliability is insufficient.
  • Temporary network testing: Provide IT teams with a portable 10GbE interface for compatible network diagnostics, staging and infrastructure validation.

KEY FEATURES

  • Up to 10GbE networking: Delivers up to 10Gbps wired Ethernet connectivity, helping reduce transfer times for large datasets and high-bandwidth workloads.
  • Thunderbolt 3 interface: Uses the high-bandwidth Thunderbolt interface to connect 10GbE networking to compatible computers without an internal expansion slot.
  • 10/5/2.5/1Gbps and 100Mbps auto-negotiation: Automatically adapts to supported network speeds, improving deployment flexibility across mixed-generation infrastructure. 
  • Marvell AQC107S chipset: Provides the network controller platform for high-speed 10GbE operation and plug-and-play support on supported Windows and macOS systems. 
  • Single RJ45 Ethernet port: Provides a familiar copper Ethernet connection for integration with existing RJ45 switching and cabling infrastructure.
  • 16K maximum jumbo frames: Supports larger Ethernet frames where the network environment and application are configured for jumbo-frame operation, potentially reducing protocol overhead on suitable workloads. 
  • Full-duplex operation: Enables simultaneous transmission and reception for efficient bidirectional network communication.
  • Auto MDI/MDIX: Simplifies copper Ethernet connectivity by automatically adapting transmit and receive pairs where supported.
  • Wake-on-LAN support: Allows compatible systems to use network-based wake functionality for remote administration scenarios. 
  • Bus-powered operation: Draws power through the host connection, eliminating the need for a separate external power adapter.
  • Fanless aluminum enclosure: Uses passive cooling for quiet operation, valuable in professional studios, offices and workstation environments where fan noise is undesirable. 
  • Certified 70cm Thunderbolt 3 cable included: Provides the required host connection cable in the box, reducing accessory procurement and deployment delays.
  • TAA compliant: Supports applicable U.S. government and regulated procurement requirements.
  • Portable external form factor: Enables 10GbE deployment without opening the host computer or installing an internal network card.

  • Strong fit for storage-heavy workflows: 10GbE connectivity can provide the bandwidth needed for high-throughput NAS, shared-storage and large-file environments.
  • Portable enterprise connectivity: The external form factor is useful for IT teams, consultants and mobile workstations that need wired 10GbE at different locations.
  • Quiet professional deployment: Fanless passive cooling avoids adding a dedicated fan noise source to offices, studios and workstations.
  • Lower deployment complexity: Bus-powered operation and the included certified Thunderbolt cable reduce the number of components required.
  • Procurement-ready specification: TAA compliance, defined network standards and a two-year warranty support formal IT purchasing requirements.
  • Longer infrastructure relevance: Multi-gigabit backward compatibility allows the adapter to remain useful as network environments transition between 1GbE and 10GbE.
