Electromagnetic Interference Mitigation in Industrial Ethernet Cabling
While standard and Industrial installations of Ethernet share many of the same characteristics, such as frame sizes, signal levels and data rates, there are significant differences as well. One of these is the physical environment in which the cabling system operates.

Industrial Ethernet vs. Comercial
Todos sabemos que Ethernet es el protocolo de comunicaciones de nivel físico de facto para la transmisión de datos entre dispositivos en una red de área local o de área extensa. Ha evolucionado a lo largo de los años para ofrecer grados más elevados de rendimiento, al tiempo que mantiene la compatibilidad hacia atrás, la fiabilidad y el coste relativamente bajo, por lo que ha conservado su popularidad.

Testing Plug-Terminated Links—Internationally
El enlace terminado en conector modular, o MPTL, en el que un tendido de cable horizontal terminado en un extremo en un conector RJ-45 se conecta directamente a un dispositivo, se está volviendo cada vez más popular para conectar varios dispositivos (desde puntos de acceso inalámbricos y cámaras de seguridad, a luces PoE y pantallas de vídeo), principalmente en los casos en los que colocar una toma y un cable de equipo no se considere práctico o seguro.

Uma visão mais detalhada dos cabos industriais de Ethernet
Last month, we published a blog about the various industrial Ethernet connectors including M-series and some new small form factor connectors like the iX and emerging single-pair Ethernet connectors. But what good is a connector designed to withstand the industrial environment without a cable that offers the same protection?

Problemas com cabo Ethernet industrial - MICE
Industrial Ethernet is very sensitive to delays caused by dropped or damaged data frames (sometimes called packets). Just a few dropped or damaged packets can cause a machine to shut down. These problems are often intermittent and can be caused by harsh industrial environments.

O que deu errado com a perda de inserção?
Have you ever carefully calculated insertion loss during the design phase and then passed your permanent link testing after installation only to find out that the channel isn’t performing once it went live?

Às vezes… é o cabo
There’s an ad that says, “We know a thing or two because we’ve seen a thing or two.” With billions of links certified by our testers and something like five more every second of every business day, we’ve seen just about every possible cabling problem. Which means we’ve seen plenty of bad cable.
