What are the performance requirements for multidrop SPE connectivity?
Specifications are provided for the insertion loss, return loss, and mode conversion loss in the link and mixing segments of a Single-Pair Ethernet (SPE) network. Connector specifications are also provided for coupling attenuation, impedance, return loss, and dielectric strength. This article begins by briefly examining where multidrop fits in the range of Ethernet connectivity options. […]
What are the PHY implementations of multidrop SPE?
There are three common physical layer (PHY) variants for multidrop Single-Pair Ethernet (SPE), basic PHY, media access controller (MAC) PHY, and transceiver. They rely on different interfaces, including a media-independent interface (MII), reduced media-independent interface (RMII), serial peripheral interface (SPI), OPEN Alliance 3-pin (OA-3P), and Ethernet advanced physical layer (Ethernet-APL). This article begins with a […]
What are the (almost) nine IEEE Single-Pair Ethernet standards?
Eight IEEE Single-Pair Ethernet (SPE) standards exist, and a ninth is expected to be announced next year. Current standards include 802.3bw (100BASE-T1), two types of 802.3bp (1000BASE-T1), 802.3ch (10BASE-T1) optimized for automated environments, three versions of 802.3cg (10BASE-T1S, 10BASE-T1L, and 10BASE-T1M), and the 802.3da single-pair multidrop segments enhancement standard approved in 2023. This article reviews […]
How does multidrop SPE work?
Multidrop capability is included in several IEEE single-pair Ethernet (SPE) standards, including the 802.3cg substandards 10BASE-T1S and 10BASE-T1M, and the newer 802.3da, which provides enhancements to 10BASE-T1M. This article begins with a brief review of SPE multidrop standards and then explores the bus timing requirements and the use of Physical Layer Collision Avoidance (PLCA) and […]
Fiber optical rotatory joints for installation in tight spaces
Orbex Group announces its 700 Series of fiber optic rotary joint (FORJ) assemblies, supporting either single- or multi-mode operation with options for wavelengths of 1310 or 1550 nanometers. Both the 1310- and 1550-nanometer options feature an outer diameter of 7 millimeters for installation in tight spaces. Additionally, each FORJ assembly features an insertion loss of […]
What are the four MICE elements and three performance levels for connectors?
IEC 11801-3:2017 provides guidance for designing physical infrastructure to support network communications in a manufacturing environment. That guidance is in the form of four MICE elements and three performance levels. The four elements of the MICE acronym include Mechanical, Ingress, Chemical/climatic, and Electromagnetic compatibility. The MICE standards define three performance levels and apply to cabling […]
