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.

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.

Considerations for Choosing Stranded vs. Solid Cable

You’re probably aware that both shielded and unshielded twisted-pair copper cable comes in either stranded or solid wire versions. There are plenty of considerations when it comes to choosing one or the other, including standards, environment, application, and cost.

História do RJ45: Um caso de identidade equivocada

Our industry commonly uses the term “RJ45” to refer to the modular 8-position, 8-contact (8P8C) interface deployed for Ethernet over copper twisted-pair network cabling despite it pretty much being a case of mistaken identity.

But since the RJ45 name has stuck, we thought maybe we’d take a closer look at the history of this nomenclature and why to this day, it remains the de facto interface for twisted-pair Ethernet applications.
