802.3bk-2013 is a technical amendment to the 802.3 Ethernet family, focused on physical layer specifications and management parameters for extended Ethernet passive optical networks. It addresses how these network links are defined and controlled in optical access environments, where transmission behavior, interoperability, and management information need to be clearly specified. For engineers, integrators, and procurement teams working with broadband network components, this standard helps support consistent design and implementation.

802.3bk-2013 overview

This amendment adds detail to the Ethernet physical layer framework for extended EPON deployments, with emphasis on signaling characteristics and management parameters. In practical terms, 802.3bk-2013 supports the technical alignment needed between optical network equipment and related management systems. It is relevant to communication and networking applications where passive optical access links must operate within defined performance expectations. As a superseded standard, it remains useful for reference, legacy support, and historical compliance review.

Typical use cases

This standard is typically consulted when designing or evaluating extended Ethernet passive optical networks for access infrastructure. It may apply to optical line terminals, optical network units, and associated management interfaces used in carrier or enterprise broadband systems. Network planners, equipment vendors, and test teams can use 802.3bk-2013 to check physical layer behavior and parameter definitions during product development, interoperability work, or maintenance of deployed Ethernet-based optical access networks.

Why this standard matters

Clear requirements for physical layer operation and management parameters help reduce integration risk in optical Ethernet systems. 802.3bk-2013 matters because it supports consistent interpretation of network behavior across devices, which is important for compliance testing, procurement decisions, and long-term support of established infrastructure. When equipment is built or evaluated against the same technical basis, teams can better control performance variation and avoid mismatches in extended EPON implementations.
