Sag Standards for Steel Strand Optical Cables
Sag - Defined by various texts (IEEE Std 100-1996, IEEE Std 524-1992, NESC) as the vertical distance between the cable and an imaginary horizontal line extending between the points where the cable is attached to the poles. Clearance requirements for aerial cables are defined in Section 23 of the National Electrical Safety Code® (NESC®). Additionally, some countries outside of the United States have adopted all or part of this code. CommScope's SpanMaster software is a tool designed for use in the calculation of sag and tension of single or multiple cable combinations under various environmental loading conditions. NESC Table 235-5 (Vertical clearance between conductors at supports) states in 1.

Innovative Applications of Fiber Optic Sensors
Fiber optic sensors (FOSs) have emerged as a critical technology for real-time, high-precision sensing across diverse fields, including structural health monitoring, biomedical diagnostics, environmental surveillance, and industrial automation. This is the power of fiber optic sensing, a technology that transforms ordinary optical fibers into the digital world's sensory network. Islam Ashry has been elected Fellow of the Institute of Physics in recognition of his impactful photonics-based research. Early stage researcher focused on laying the foundations for the emerging field of Integrated Sensing and Communications (ISAC).

Spectrometer Analysis of Carbon Steel
Optical Emission Spectroscopy (OES) is a highly accurate method for measuring carbon content in steel. It involves creating a plasma from the sample using an electric arc or spark and analyzing the emitted light to determine the elemental composition. In past articles, we discussed the importance of identifying the carbon content in steel because the addition of carbon into steel helps increase properties such as corrosion resistance, weldability, ductility, and hardness but could cause unexpected consequences. This mobile metal analyzer flaunts its superior performance especially when exact metal analysis is required, when materials are difficult to identify or when. To analyze the elements in metals with cordless handheld instruments, Fraunhofer ILT is developing a method and con-ceptual setup to use laser-induced breakdown spectrometry (LIBS) with highly integrated components; furthermore, it is investigating its analytical performance in the laboratory.
