This standard describes the system-level requirements needed to provide service-level, multi-vendor interoperability of Ethernet Passive Optical Network (EPON) equipment. The specifications complementthe existing IEEE 802.3 and IEEE 802.1 standards, which enable the interoperability at the Physical Layer and Data Link Layer.1 Specifically included in this specification are - EPON system-level interoperability specifications covering equipment functionality, traffic engineering, and service-… read more level quality of service/class of service (QoS/CoS) mechanisms; - Management specifications covering equipment management, service management, and power utilization. read less

This standard specifies extensions to IEEE Std 1149.1(TM) that define the boundary-scan structures and methods required to facilitate boundary-scan-based stimulus of interconnections to passive and/or active components.1 Such networks are not adequately addressed by existing standards, including those networks that are ac-coupled or differential. The selective ac stimulus generation enabled by this standard, when combined with non-contact signal sensing, will allow testing of the connections… read more between devices adhering to this standard and circuit elements such as series components, sockets, connectors, and integrated circuits (ICs) that do not implement IEEE Std 1149.1. This standard also specifies Boundary-Scan Description Language (BSDL) extensions to IEEE Std 1149.1 required to describe and support the new structures and methods. read less

This standard specifies the performance requirements and test methods for portable passive imaging radiation devices (PIRDs) used to detect, localize, and identify gamma-ray emitting radioactive materials in the form of point or distributed sources. PIRDs may also have the ability to characterize identified ionizing radiation sources as to their physical shape and size.

The recommended practice defines test approaches to quantify the interference of passive intermodulation (PIM) from handheld devices, base stations, and satellite earth stations. Current PIM noise tests for communication components/devices/antennas/systems do not work well at extremely low PIM levels or high transmission power levels, for example where PIM noise falls below -150 dBc.

The scope of this project is to amend IEEE Std 802.3 to add physical layer specifications and management parameters for point-to-multipoint passive optical networks supporting MAC data rates of 25 Gb/s or 50 Gb/s in the downstream direction and 10 Gb/s, 25 Gb/s, or 50 Gb/s in the upstream direction, with distance and split ratios consistent with those defined in IEEE Std 802.3. It also extends the operation of Ethernet Passive Optical Networks (EPON) protocols, such as MultiPoint Control… read more Protocol (MPCP) and Operation Administration and Management (OAM). read less
