Executive Summary
10 Gigabit Ethernet (10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10GbE defines only full-duplex point-to-point links which are generally connected by network switches; shared-medium CSMA/CD operation has not been carried over from the previous generations of Ethernet standards so half-duplex operation and repeater hubs do not exist in 10GbE.
The adoption of 10GbE has been more gradual than previous revisions of Ethernet: in 2007, one million 10GbE ports were shipped, in 2009 two million ports were shipped, and in 2010 over three million ports were shipped, with an estimated nine million ports in 2011. As of 2012, although the price per gigabit of bandwidth for 10GbE was about one-third compared to Gigabit Ethernet, the price per port of 10GbE still hindered more widespread adoption.
Architecture & Design
The 10GbE standard encompasses a number of different physical layer (PHY) standards. A networking device, such as a switch or a network interface controller may have different PHY types through pluggable PHY modules, such as those based on SFP+. Like previous versions of Ethernet, 10GbE can use either copper or fiber cabling. Maximum distance over copper cable is 100 meters but because of its bandwidth requirements, higher-grade cables are required.
To implement different 10GbE physical layer standards, many interfaces consist of a standard socket into which different physical (PHY) layer modules may be plugged. PHY modules are not specified in an official standards body but by multi-source agreements (MSAs) that can be negotiated more quickly. Relevant MSAs for 10GbE include XENPAK (and related X2 and XPAK), XFP and SFP+.
Performance & Thermal
The performance of 10GbE is significantly higher than its predecessors. With a bandwidth of 10 gigabits per second, it can support high-speed applications such as data centers, cloud computing, and high-performance computing. The thermal design of 10GbE devices is also important, as they can generate significant heat during operation.
In 2017, Apple made built-in 10 Gigabit Ethernet standard in their iMac Pro. By 2022, the price per port of 10GBase-T had dropped to $50 - $100 depending on scale. In 2023, Wi-Fi 7 routers began appearing with 10GbE WAN ports as standard.
Market Positioning
The market for 10GbE is growing rapidly, driven by the increasing demand for high-speed networking solutions. The adoption of 10GbE is being driven by the need for faster and more reliable networking solutions in data centers, cloud computing, and high-performance computing applications.
However, the market for 10GbE is also facing challenges, such as the high cost of 10GbE devices and the limited availability of 10GbE-enabled devices. Despite these challenges, the market for 10GbE is expected to continue growing in the coming years, driven by the increasing demand for high-speed networking solutions.
