About 14. Other Wired Networks

While Ethernet prevails, alternative wired technologies serve specialized niches where its characteristics prove inadequate or excessive. Token Ring and FDDI offered deterministic latency for legacy industrial systems, ATM provided guaranteed QoS for integrated voice/data/video backbones, and Fibre Channel delivers ultra-low-latency lossless storage networking, each reflecting design priorities optimized for specific application domains rather than general-purpose connectivity.

Broadband access technologies like DSL, DOCSIS cable modem, and PON fiber-to-the-home extend network reach beyond LAN boundaries using existing copper or passive optical infrastructure. These systems employ unique PHY/MAC adaptations to overcome distance limitations, noise impairments, and shared-medium constraints inherent in last-mile deployments, illustrating how wired networking extends far beyond office walls to connect millions of residential and business subscribers to global internet services.
