Fluke Networks previews single-pair Ethernet testing

Fluke Networks demonstrated a prototype single pair Ethernet (SPE) adapter for its DSX-8000 at the Rockwell Automation Show. SPE is making waves in the industrial-automation world as a potential replacement for fieldbus architectures. The adapter is being made in very limited quantities and is currently only available to industrial automation and cabling manufacturers for their use in labs but has been released with the expectation that SPE will become widely adopted.

Webinar: Best Practices in Enterprise Fiber Connectivity

Fiber connectivity is essential for the physical infrastructure in any enterprise or data center network. While it certainly has advantages, there are also challenges that come along with fiber. Contamination is the #1 cause of troubleshooting in fiber networks, so it is critical that anyone working with fiber is aware of and implementing best practices when handling, installing, or testing fiber connections. During this one-hour session, we will take a closer look at fiber connectivity and educate attendees on the impact that contamination has on fiber connections and network performance. We will also provide guidance on best practices and standards that are in place to ensure clean connections.

How fiber cleanliness is crucial to 5G connectivity

To assure reliability and performance, and avoid potential problems such as insertion loss (weakened signal), back reflection (signal is diverted back to its source), or a total system shutdown, it’s  essential that all connections are perfectly clean. This is especially important with a 5G network because every milliwatt of power is necessary for optimum connectivity and peak performance.

Bandwidth and Data Rates

The terms bandwidth and data rates are often used interchangeably, but they are in fact very different if you work in the cabling world. Your internet provider may advertise a bandwidth of 500 megabits per second (Mbps). In that case, they actually mean data rate. In the cabling world, bandwidth is a property of the cable – its ability to transmit a signal that’s intelligible at the far end. Any signal put on a copper or fiber link will degrade as it gets to the far end. This is a result of simple loss, but also more complex factors such as return loss (reflections), and in the case of copper, crosstalk. Vendors design their copper and fiber cabling to be able to deliver these raw signals (bandwidth) at higher rates.
