## Summary description

External Ethernet adapter Sonnet TWIN10GM‑SFP‑TB provides two independent 10 Gb Ethernet ports via SFP28 modules and connects to a host through Thunderbolt 3. Designed for high‑speed networking, it suits workstations and media systems requiring dual 10 Gb links, low latency, and flexible transceiver choice. Ideal for professional audio/video, storage and network aggregation.

## Long description

The Sonnet TWIN10GM‑SFP‑TB is an external Ethernet adapter that provides two independent 10 Gb Ethernet ports using SFP28 module slots and connects to a host computer via a Thunderbolt 3 interface. It is engineered to deliver low-latency, high-throughput network connectivity for workstations, storage systems, and media-production environments where dual 10 Gb links and flexible transceiver support are required. The compact external enclosure frees a system from internal card installation while offering full-duplex 10 Gigabit performance on each port.
Advantages
The adapter supports two separate 10 Gb Ethernet channels that operate independently, enabling link redundancy, link aggregation, or simultaneous connections to different networks. Use of SFP28 slots allows selection of suitable optical or copper transceivers for the specific fiber type or distance, providing deployment flexibility. Thunderbolt 3 connectivity supplies high-bandwidth, low-latency host attachment without occupying PCIe slots, and the external form factor simplifies installation and portability for multi-workstation environments.
Suitable for
High‑resolution media editing and real‑time audio/video production requiring stable 10 Gb links
Network attached storage (NAS) and SAN clients that need dual 10 Gb connections for throughput or redundancy
Workstations used for virtualization or server offloading where additional high‑speed NIC ports are necessary
Network aggregation, link teaming, and bandwidth‑intensive data transfers over fiber or direct‑attach copper
Key specifications
Two independent 10 Gigabit Ethernet ports via SFP28 module slots
Thunderbolt 3 host connection for high-bandwidth external attachment
Support for optical and direct‑attach transceivers compatible with SFP28
Full‑duplex 10 Gb performance on each port
External compact enclosure suitable for desktop and rack-adjacent use
Low-latency operation designed for professional media and storage workflows
How to use
Install compatible SFP28 transceivers into the module slots according to your cabling and link-distance requirements, then connect the adapter to the host computer using a Thunderbolt 3 cable. Configure network parameters in the host operating system or network management software, assigning IP addresses, enabling link aggregation or failover if needed, and adjusting MTU or offload settings according to your network design. Monitor link status and performance through the host’s network utility or the adapter’s driver tools.
Usage recommendations
Choose transceivers certified for your fiber type and expected distance; verify Thunderbolt 3 compatibility and driver support for your operating system. For maximum throughput, enable link aggregation or spread traffic across both ports when supported by your network switch. Maintain airflow around the enclosure to avoid thermal throttling during sustained high-bandwidth transfers.
