## Summary description

The Sonnet Twin25G is an internal fiber card designed for high-speed data transfer with a maximum rate of 25000 Mbit/s. It connects via PCI Express and provides reliable wired connectivity, making it ideal for demanding applications that require fast and efficient data handling.

## Long description

The Sonnet Twin25G Internal Fiber PCIe Card provides 25GbE fiber network connectivity for computers with PCI Express slots or for use in Sonnet Thunderbolt PCIe expansion systems. Designed for bandwidth-intensive workflows such as post-production shared storage, the card delivers up to 25,000 Mbit/s over fiber, uses SFP28 modules, and is compatible with existing optical infrastructure used for 10GbE. The package includes both full-height and low-profile mounting brackets for installation into any PCIe slot.
Advantages
The Twin25G offers higher throughput than 10Gb Ethernet while reusing the same fiber infrastructure, reducing the need for multiple 10Gb links. It supports NVMe over Fabrics (NVMe-oF) target offloads to enable efficient NVMe storage access with minimal CPU involvement, lowering latency and improving storage performance. The card is a cost-effective solution for adding 25GbE to Mac Pro and other PCIe-equipped systems and can be installed into a Sonnet Echo Thunderbolt expansion unit to provide 25GbE connectivity for systems without internal slots.
Suitable for
Post-production shared storage workgroups
High-bandwidth file servers and NAS systems
NVMe over Fabrics (NVMe-oF) storage networks
Workstations and servers requiring 25GbE fiber connectivity

How to use
Install the Twin25G into an available PCIe slot in your computer or into a Sonnet multi-slot Echo Thunderbolt expansion system. Fit either the full-height or low-profile bracket provided to match the host chassis. Install the appropriate driver for macOS, Windows, or Linux, install the included SFP28 modules, and connect fiber cables to a 25GbE-capable switch or directly to 25GbE storage. Configure network settings via macOS Network preferences, Windows Device Manager (or network settings), or Linux command-line utilities or GUI tools.
Usage recommendations
Use 25GbE-capable switches and certified SFP28 modules and fiber cables to achieve full performance. For NVMe-oF deployments, verify switch and storage compatibility with NVMe over Fabrics to take advantage of target offloads and minimize CPU load.
