Faster Transfers Across Existing Cabling | home. office. gaming. media servers.

Have you recently installed a new Ethernet switch capable of supporting 2.5Gb Ethernet (NBASE-T)? Interested in more than doubling network performance at every desk - economically - using the existing Cat 5e cabling already in your home or office walls? Sonnet has what you need - Solo2.5G™ PCIe Card, an inexpensive Ethernet adapter that adds an RJ45 port with superfast 2.5 Gigabit network connectivity to Windows and Linux computers with PCIe® card slot.

  • Increase productivity with faster downloads for work-from-home users
  • Experience quicker file transfers between PCs and Network Attached Storage (NAS) in the office or at home
  • Enjoy faster speed and lower latencies for E-sport games and live streams
  • Achieve swifter transfers for multiple users from home media servers

Same Connector and Cabling | Faster Speeds with 2.5 GbE Switch

Featuring NBASE-T technology (also known as multi-Gigabit Ethernet), Solo2.5G PCIe Card supports 2.5 Gb/s link speeds (2.5GBASE-T) over common Cat 5e or better cabling when used with a compatible 2.5Gb Ethernet switch or 10Gb Ethernet switch with NBASE-T support. Very affordable 2.5GbE models from D-Link, Netgear, QNAP, TP-Link, TRENDnet, and others are available now.

Connected to the right switch, you can get great performance gains - 250 percent the speed of Gigabit Ethernet - without rewiring! In case you're connecting to a switch without NBASE-T support, the Solo2.5G also supports 1 Gb/s and 100 Mb/s link speeds.

250% the Speed of Gigabit Ethernet | Upgrade to 2.5G Ethernet with Existing Cat 5e Cable

Add 2.5GbE connectivity with a Solo2.5G PCIe Card

Upgrade to 2.5G Ethernet with Existing Cat 5e Cable

Just simply add Solo2.5G PCIe Card - no need to rewire your building; existing wiring already supports up to 2.5 Gb/s.
