  1. 1. DIAGNOSING ETHERNET CABLES USING TIME DOMAIN REFLECTOMETRY IN ETHERNET CIRCUITS

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Anton Sundqvist; [2023]
    Nyckelord :;

    Sammanfattning : Ethernet cables are a vital component in modern systems, providing reliable data transmission between devices. However, like any other physical component, these cables are subject to wear and tear. Depending on several factors, this wear and tear can happen at different rates, and unplanned stops in a system must be avoided. LÄS MER
