"IEEE802.3标准文档：100 Mb/s基带网络介绍和物理层规格"

The IEEE802.3 standard document provides specific requirements for telecommunications and information exchange between systems in local and metropolitan area networks, focusing on the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access method and Physical Layer specifications. This section, which covers Clause 21 through Clause 33 and Annex 22A through Annex 33E, introduces the 100 Mb/s baseband networks, specifically the 100BASE-T type. The 100BASE-T type is a high-speed networking standard that operates at 100 Mb/s over twisted pair cabling, providing a cost-effective and efficient solution for local and metropolitan area networks. It utilizes the CSMA/CD access method to regulate network access and minimize collisions, ensuring reliable data transmission. The standard document outlines the technical specifications, requirements, and guidelines for implementing 100BASE-T networks, including the physical layer specifications for cabling and connectors, as well as the procedures for collision detection and media access control. It also addresses the performance characteristics, interoperability, and compatibility aspects of 100BASE-T networks to ensure seamless integration with existing network infrastructure. Overall, the IEEE802.3 standard for 100 Mb/s baseband networks, type 100BASE-T, offers a comprehensive framework for deploying high-speed LAN and MAN environments, promoting efficient data exchange and communication between systems. With its detailed provisions and recommendations, the standard contributes to the advancement of information technology and telecommunications, catering to the evolving needs of modern businesses and organizations.
