I swear, I can empathize that Belden doesn't make it easy for you to choose a cable for a specific application. A week doesn't go by that someone isn't complaining to me that we have too many choices.

I tell most people that we make "6,000 different kinds of wire and cable". What's the actual number? I don't really know, and I don't know if anyone knows. As the introduction of new technologies speeds up, we bring out more and more new products, so that "total" is a moving target.

It's no wonder that often, when I suggest a cable to a customer, they get angry. You see, this cable may have been in our catalog for 20 years and they didn't know about it. They’ve been struggling with some old cable from the Dark Ages, wishing there was a better way, and it has been sitting there waiting for them. I would be angry too.

Last month I visited a leading system integrator for TV studios and outside broadcast (OB) trucks. It is always impressive to see how full these trucks are packed with equipment for audio, video, intercoms, air conditioning and satellite dishes – and don’t forget the workspace for a crew of up to 25 people! Everything needs to be well thought-out to be clean, compact and super-efficient. In the end, this is a fully functioning professional TV studio on wheels… with two limitations: one, there’s much less space than in a permanent creation, production and delivery area; and two, there are the over-the-road axle weight requirements.

The OB truck that I saw will be used, once it’s finished, for football events only. For this kind of application, HD production has become a standard, but the system integrator also has to take into account the fact that the video signals can be run on 3D cameras as well. With each new OB truck they outfit, they further fine-tune and improve the design, equipment and capabilities, based on their experience with preceding trucks and changing end user specifications and applications.

We recently received a letter from Jim Schultz in Warren, CT and thought we'd share:
Morning Steve,

I have been meaning to write for almost a year now to extol the virtues of this excellent microphone cable.

30+ years ago, when I was doing broadcast and remote work aside from my "regular" job of air personality, production director and assistant CE for an AM/FM combo here in Western CT, I decided to bite the bullet, spend some money, and make up some microphone cables that would last for a while. I bought a 500 foot roll of 8412, a bunch of Switchcraft XLRs, and went to work making up 10 fifty footers.

If you play with coax, short for coaxial cable, you probably know this it is available in a number of different impedances. The most common is 75 ohm, like video cable or antenna cable, but in fact our products range from 32 ohms up to 124 ohms.

Why all these different numbers? It's not an accident of course, and there is a reason for each one. Today, we're going to take a quick look at 50 ohm coax cable.

Belden makes hundreds of 50 ohm cables, including a whole line of ultra-low loss versions (Belden 7805 to Belden 7977). The two largest versions (Belden 7976 and 7977) are shown in the photograph below. They are HUGE. The 7977 has a diameter of .600" six-tenths of an inch! This is the largest coax cable that Belden makes.

Many existing variable frequency drive (VFD) installations are using wrong cables. Often, interlocked armor TECK or continuously welded and corrugated aluminum armor (CCA) cable are used to connect the VFD to the motor. These cable types will release excessive electrical noise in many installations - and this electrical noise can wreak havoc with the sensitive electronic components, network cabling and other sensitive wiring found in most modern industrial facilities

The solution is to use specially-designed VFD cable with a foil braid or copper tape shield and suitable ground wires. For larger cables it becomes important to use a symmetric ground design to balance the induced ground currents. Compared to TECK or CCA, this type of VFD cable provides superior performance in terms of common mode current (CMC) containment, and in other areas.

Do you believe that all networking cables are equal?

If you're a regular visitor to this blog, your answer is certainly "No."

In particular, harsh environments require that networking cables be built to meet the environmental challenges in order to insure signal transmission quality. Environmental hazards include EMI, chemicals, water, crushing, flex and temperature extremes.

So what should you look for in a cable to stand up to these hazards?

Frank Koditek, our product line manager – industrial cables, will present exactly what you should look for in the upcoming Cabling Installation & Maintenance Magazine Webinar: Cabling for Industrial and Other Harsh Environments.

One day, Georg Simon Ohm did an experiment. He built a voltaic pile - what we would now call a battery. To judge the voltage, he attached a wire to each end, held one in his hand and touched the other to his tongue. Ouch! He did notice one interesting thing. If he stuck with copper wires and he went to a larger wire, his tongue hurt more! I am not making this up! You can Google it.

That told him there must be some relationship between the size of the wire and the voltage running down that wire. He soon realized that this could be described in a formula, the formula we now call Ohm's Law. He told this to his scientific friends and they were aghast! The idea that there was a relationship between voltage and current and the size of the wire (resistance) was so controversial, that they begged him not to reveal it. And so these results were not published until his death. It is pretty much the same story as Copernicus and the sun-centered planets. And we're still using Ohm's Law today.

When you deal with high frequencies, above around 100 MHz, you have entered the zone of the "transmission line." It has to do with the wavelength of the signal, and that is a discussion we'll have in future blogs. But what it means is that the impedance of the cable is now important and you have to match the impedance of the source and destination devices.

This also means that everything in-between must match the impedance chosen and, by "everything," I mean cable, connectors, patch panels, patch cords, adaptors, bulkheads, feedthroughs - everything! It also means that any variation in impedance can affect the signal on the line. This is true for every transmission line, whether we're talking about a 50kW RF signal going up to an antenna or an HD video signal going between boxes. Of course, in these two examples the impedance is different (50 ohms for that high-power line and 75 ohms for that video cable).

Networking safety, uptime and control should be key factors in selecting networking cabling and hardware components such as switches and routers. 'Industry' is a broad term encompassing a multitude of diverse operations — from discrete manufacturing of every kind, to processing of foods and beverages, pulp and paper, chemicals, oil/gas and petrochemicals, to commercial and government sites such as power generation plants, wind energy farms, water and wastewater treatment facilities, airports and transportation hubs, military bases, ships and shipyards, rail yards, tunnels, dams and bridges.

Wow. This is turning out to be the best NAB show we've had in a long time. We received more leads in the first two days than we have had from an entire show in recent memory. And it's not just us. Every other booth seemed equally busy. It's so busy, I would not be surprised if the total attendance exceeded the magic 100,000. Of course, our popularity has been based on many things, including the three live demos we have going for new products. First is our demo of Belden 1776, a revolutionary cable. This is the strongest microphone cable we've ever made, and quite possibly the strongest ever manufactured by anyone.

At the show, we suspended a hanging chair from the cable and attached a working microphone. We've had Renee Staul, from our marketing department, and Jessie Carmona from our Mexico sales office, each sit in the chair and entice the crowd to see them suspended by a microphone cable.

Virtually all TV broadcasters in the USA have gone digital. Even Hollywood has converted from film to digital images. While some of these cameras record the data on hard drives or SSD (solid-state memory chips), at some point you're going to send this data, those digital images, from Point A to Point B. If you want to carry the hard drive or SSD from place to place, that's fine (so-called "sneaker net") but it is time-consuming and inefficient. Why not put that signal on a cable to move it from place to place? That's what most broadcasters do. And, while you could do this on fiber, converting from electrons to photons and back again at the other end, the economical and simple way is still over copper cable, most commonly coax cable.
