Keeping production systems up and running is the primary concern of controls engineers. Nowadays, part of achieving high availability includes protecting networks from accidental events and unforeseen security threats.
In speaking to our customers about this challenge we found out that they would like an all-around device that is easy to use and that can be deployed in the harshest industrial environments. Today I want to introduce you to a handy new tool for meeting these requirements.
Introducing the EAGLE One Industrial Security Router
Our just announced EAGLE One security router is what we like to call “the Swiss Army knife of routers”. It provides comprehensive industrial network security with a very good price/performance ratio. Plus it is rugged enough for use in industries such as oil and gas.
Although in my last blog I mentioned the different spec work currently underway at SMPTE, it’s time once more to take another look at 4K.
Current situation: HD is the new standard
High definition (HD) has reached European broadcast TV. It is now the new standard definition and considered to be mainstream. Having said that, at Belden we take into account that our professional broadcast customers may be managing two different HD formats.
The first of these is interlaced scanning with 720 to 1080 horizontal lines (e.g. 1080i). Each scan displays alternate lines in the image raster, and two complete scans are therefore required to display the entire image – also known as HD/1.5Gbps.
The other one is progressive scanning with 1080 horizontal lines (1080p). Each scan displays every line in the image raster sequentially from top to bottom – and is also known as HD/3Gbps. This format offers less jitter, with more stable and flicker-free video quality and sharpness. Because of the new 4K format, Belden uses the term 2K/3Gbps instead of HD/3Gbps.
Both HD formats are specified 2006 in the standards of SMPTE (the Society of Motion Picture and Television Engineers) under ST 292 for interlaced scanning and ST 424 for progressive scanning. These specifications are defined for 75 ohm coaxial cables and 75 ohm BNC connectors. By the way, ST 297 covers all SDI rates from 143Mbps to 3Gbps with optical fiber cabling infrastructure.
Most important for the broadcaster is to know how far he can transmit the signal over a single coax cable. Belden’s 1694A, for example, can have a minimum run of 113 meters with HD and 78 meters with 2K signals. These lengths can be improved when using our HD BNC connectors – for example 140 meter at HD or even further. A Gennum chip produced by Semtech can extend this to 230 meters.
My wife and I collect stuff, and every so often, we start filling a big garbage bag with things for Goodwill. I think they do good work in the community. I even shop there sometimes. (You’d be surprised what you can pick up in speakers, amps, turntables and CD players or other gear from “yesterday”). In one of our Goodwill bags we threw in a Mickey Mouse stuffed toy. We soon found that they only accept brand new unused toys, so Mickey was returned. Mickey knocked around the back of my wife’s car for the better part of a year. During Christmas, I attached some plastic Poinsettia to the front of this PT Cruiser with a few wire ties. Looks festive. After Christmas was over, we took off the Poinsettia. As I drove around, I thought about what we could put in the front of the car that wasn’t seasonal. And then it hit me – how about Mickey?
In an era where loss budgets are more stringent than ever and most manufacturers are publishing both typical and maximum insertion loss values, knowing which loss values to base the design of your channel on is more important than ever.
The idea of a loss budget is to ensure that the application will function over the installed channel. Rather than using the best possible connector loss values, designers should be conservative and give themselves some margin.
In other words, play it safe and base your testing loss limits on the manufacturer’s specified “maximum” insertion loss values.
When it comes to designing and upgrading a data center, ensuring a successful outcome doesn’t happen by accident—it is the direct result of diligently executing a strategy and taking a long-term view.
As pointed out in a recent letter to associates from Belden’s President and CEO, John Stroup, these are the same values responsible for many successful outcomes, including innovation achievements.
While some might name the likes of Apple or Facebook when asked which company epitomizes innovation, Belden is certainly doing its part within our industry. Recently ranked No. 1 Innovator in the industrial components industry by the Patent Board, Belden received the highest score for technology strength for the second consecutive quarter—bettering a list of impressive companies like Eaton, Schneider, Panasonic, Rockwell, Emerson, United Technologies, and Illinois Tool Works.
Based on the tracking of global patent activity and measured through the criteria of patents granted, science strength, innovation cycle time, industry impact, technology strength and research intensity, this recognition demonstrates Belden’s tireless pursuit of innovation.
In fact, Belden has secured more patents and pending applications in connectivity technology than any company worldwide!
A customer was asking me today about our warranty. Well, on the back of our Bill of Sale (which covers everything) it says 10 years. But there are a lot of other products with a 25 year warranty, especially in our data line. We even have some products, like Belden 1872A “MediaTwist”, with a lifetime warranty. “You mean FOREVER ???” said an incredulous European Belden salesperson. Well, sure. That warranty says we made the cable the way we agree to make it. And if it turns out that we made it wrong and it fails, we’ll replace it for free. It’s definitely something that motivates us to make it right the first time. Of course, sometimes we make it even better than that, or a customer just assumes that our cables are the best (thank you very much) but then does things that the cable was never designed for. And this leads to my story.
Make sure your cables are designed to handle the right voltage
The reaction of a cable when subjected to direct or alternating current flow can differ according to the cable design. Cable conductors that oppose or resist electrical current in an application can overheat, which may degrade the protective insulation, resulting in fire ignition, fatalities and equipment damage.
Unfortunately there are many inferior cables in the market today, and they can be hard to identify. What makes it tricky is that cables can appear to have comparable basic specifications, yet record very different DC Resistance or Impedance results.
On Cable Talk we discuss how the quality of a cable’s electrical performance is based on the quality of the conductor and we show how, if the opposition or resistance is too high for the current that is travelling through the conductor, this can lead to signal distortion, system failure, fire and/or major maintenance and repair costs.

During autumn, we featured a blog on raised floors by guest blogger Chris Ouellette, a Senior IT Specialist of Data Centre Services for IBM Canada, Ltd.
Chris did an excellent job at covering some of the key reasons why doing away with raised floors in the data center isn’t as straight forward as one might think.
As a follow up to that blog, I thought we’d take a look at some of the other drivers moving cabling out of the floor and overhead.
“There is no expedient to which a man will not resort to avoid the real labor of thinking.”
This quote from Sir Joshua Reynolds was Thomas Edison’s favorite quote. And it is true of everyone, including you and me. We go through life expecting things to stay the same, expecting things to be predictable. That way we don’t have to think, we don’t have to have “Plan B”. And this was never presented to me in such a blatant way as a list of the top ten shows on tour that appeared in a recent magazine. All of them were major names: country artists, pop stars, rock groups, Latin artists. These shows were designed by the top names in the roadshow industry. And each company included an extensive list of what they used; microphones, mixers, amplifiers, and speakers, pretty much everything.
