10 Gigabit Ethernet represents the family of Ethernet systems that can provide maximum data transmission speed up to 10 GB/sec. This system is also popular as 10GE, 10GbE, or 10 GigE, was defined under 802.3ae IEEE standard in 2002 that defined the basic 10 Gigabit Ethernet system with a set of optical fiber media standard. Gigabit Ethernet standard supports only full-duplex mode of communication. Several standards available are the 10GBase-R, 10GBase-X, 10GBase-T, and 10GBase-W. 10GBase-R standard is using 64B/66B signal encoding over the optical fiber media system with Ethernet specifications as 10GBase-SR, 10GBase-LR, 10GBase-ER, and 10GBase-LRM. 10GBase-X is based on 8B/10B signal encoding with specifications; 10GBase-LX4 over optical fiber media systems and 10GBase-CX4 over copper media systems.
Applications of Switch/Router
Published in James Aweya, Designing Switch/Routers, 2023
10 and higher Gigabit Ethernet interconnects are fast becoming the backbone technology for enterprise and service provider networks (Figure 7.8). High-performance multi-gigabit Ethernet interfaces give enterprises the functionality and scalability they need to build their next-generation backbones cost-effectively. For example, 10 Gigabit Ethernet has matured to the point that it provides cost-effective network connectivity with high bandwidth and low latency, in addition to all the available network management capabilities that come with IP and Ethernet networking. The wide-scale adoption of multi-gigabit Ethernet is mainly driven by the following factors:There are now switches with 10, 25, 40, 100, and higher Gigabit Ethernet interfaces in the market that provide the line-rate ACLs, QoS, and queuing features needed for network security, performance, and availability.10 Gigabit Ethernet, for instance, is competitive to InfiniBand and Fibre Channel, and delivers the bandwidth and low latency required to support storage networking. The bandwidth and latency characteristics of 10 Gigabit Ethernet provide a common transport mechanism for supporting data and storage traffic across the entire Enterprise.Multi-gigabit Ethernet interconnects simplify backbone engineering by enabling remote buildings, data centers, and storage facilities to appear as simple extensions of the LAN.Multi-gigabit Ethernet interconnects reduce the need to support other parallel MAN and WAN technologies and connections by providing transport over multiple wide-area media: SONET/SDH, DWDM, CWDM, and dark fiber. Ethernet is a flexible technology supporting short distances across the LAN, intermediate distances across the MAN, and long haul across the WAN with DWDM, CWDM, and SONET/SDH compatibility.Today’s enterprise networks are critical to the operations of organizations. Network administrators are concerned about zero downtime on the network, securing the network from attacks (DoS attacks, cyber-spying, malicious users), and maintaining data integrity and confidentiality, without adding excessive cost or impacting performance. All of these require a structure that allows for graceful growth as the enterprise grows. To build a network that will continue to provide non-blocking access between users and resources as it grows, the enterprise must deploy a backbone that can scale with meshed nodes and redundant paths. This topology requires a switch/router that can support multiple multi-gigabit Ethernet trunks and forward traffic at a line rate between them.

To transmit an uncompressed SDI video stream over Flexilink, 10 Gbps ports are needed. This 10 Gbps port can also be used to transmit multiple compressed video streams as well. A single AP will have 160 frames instead of 16 which enables sending SDI uncompressed. However, those video streams in the 4 K format are not supported by Flexilink since they have a data rate exceeding 12 Gbps. The frame layer structure of Flexilink implementation over a 10-gigabit Ethernet link for uncompressed/compressed SDI video stream is shown in Figure 4.
