Don't underestimate the value of cabling skills

Today's blog post delves into the Cabling Installation & Maintenance mailbag...

Hi Patrick and Matt,

I read [your recently posted item regarding] Turck's white paper, Ethernet Cable: A Guideline to Implementing Solid or Stranded Cables. On page 2, referencing the TIA/EIA standards, the paper's author states, "By providing user-friendly instruction, as well as topology, connection points, termination points and media definitions, users can wire a building without prior knowledge or special skill."

Excuse me!

I have been in the cabling business all my life. I am highly offended by this statement. I am sure I am not the only one. I have worked with hundreds of cabling professionals over the years who are true craftsman and take pride in their work. I think the author has insulted anyone in our business who cables a building according to the specifications, building codes and especially those detailed individuals who make sure that every cable is dressed properly as if creating a masterpiece.

Just my two cents.

Hi Andy,

Your point is well taken: empirical data certainly suggests that the TIA/EIA specs for designing and implementing structured cabling infrastructure are only getting more complex -- which is exactly why the Fiber Optic Association (FOA) recently announced that it's creating its own standards for installers and users.

Thanks for the feedback!

Google Fiber installations kick off

As reported at the Google Blog, after months of building-in new fiber infrastructure, the Internet search giant announced that it is officially starting to connect homes in Kansas City.

"There are two stages to getting you connected," Google informs its Kansas City customer base via the blog post. "First, we'll pull your fiber from the street to the side of your house; we’ve already done this for several houses in Hanover Heights. Then we'll get in touch with you to schedule the second stage, your in-home installation...If you live in Hanover Heights and see a new box on the side of your house (and have gotten a Google Fiber sticky note on your door), look for an email or phone call from us in the next few days to schedule an appointment. When the installer arrives, he/she will ask you about where you want your devices and then get to work."

Google Fiber has put together a short video to help customers further understand what to expect.

As noted by Light Reading, Google Fiber's 1Gbit/s broadband service carries a price tag of $70 per month, or can be had as part of a subscription TV bundle that starts at $120 per month. A "free" 5Mbit/s downstream and 1Mbit/s upstream service is being pitched to customers who pay a $300 construction fee.

Google's chief FTTH competition in the Kansas City area includes Time Warner Cable, AT&T, SureWest Communications and Comcast.

Cisco CEO: 'Government regulation of IT will not achieve intended objectives'

Cabling Tweets' top 10 Tweets for Tuesday, October 23, 2012:

In a wide ranging talk conducted just before noon on October 23 at the Garnter Symposium/ITExpo 2012 in Orlando (1), Gartner's Richard Hunter and David Willis took the stage (2) to interview Cisco CEO John Chambers.

Mincing no words, Chambers said that "over the next 5 years the fabric of IT will be deeply embedded with every business process (3)."

"Of the top 6 IT vendors, only three or four will be in top six 5 years from now," he added (4). "Any of the top 6 vendors who think they will be in top 6 in next 5 years are probably wrong," the Cisco CEO reportedly said (5) -- owing to the "magnitude of the changes" that stand before the telecom and datacom industries in the coming years.

To that end, at the talk, Chambers' main contention (6) was that "the Internet of Everything will be the platform of the future" -- to which he added provocatively (7) that "government regulation of IT will not achieve [its] intended objectives."

And that wasn't all, in terms of provocative networking industry takes from the Cisco chieftain -- just see his reported comments on competitors Oracle (8) and HP (9).

"When I compete, even with friends, I compete to win (10)," said the Cisco CEO.

Enterprise BYOD heroes; Cisco data center woes; Cool cars meet cool Icelandic data centers

CablingTweets' Top 5 Cabling Industry Tweets for October 11, 2012:

Heads up IT security managers(1)! You can look like a hero if you lead your organization's charge to establish enterprise BYOD policies -- despite any physical infrastructure challenges you may encounter.

If the prospect of this leaves you "searching" for answers, you know where to turn (2).

To that end, did you know (3) that "Google, Amazon, Microsoft, and Facebook buy more networking hardware than practically anyone else on earth? But at the same time, they’re buying less and less gear from Cisco, HP, Juniper, and the rest of the world’s largest networking vendors?" So writes Wired's Cade Metz in a recent exclusive article.

Related news: HP's enterprise services business tumbles

Moving from "discussion" to "call-to-action", how about...Smart Cities (4)! As addressed by Cisco -- who given the claim just made above, you can maybe see feeling impelled to make just that sort of move. (Come to think of it, Cisco's been boogieing quite a bit these days in the big-time data center space -- see the company's recent fast breakaway from Huawei-ZTE for selling critical facilities equipment to Iran.)

Cooler heads prevail elsewhere in the industry -- for instance, as in Iceland's modular data center space (5). It begs the question, which is cooler -- the cars or the facilities?

U.S. Senators call for executive order to boost cybersecurity of nation's critical infrastructure

United States Senators Richard Blumenthal (of Connecticut) and Chris Coons (of Delaware) have written a letter to President Barack Obama requesting that he issue an executive order dealing with cybersecurity. In a press release, Senator Blumenthal's office explained that he and Senator Coons "were part of a bipartisan effort to build consensus on critical infrastructure provisions of the Cybersecurity Act of 2012," and said that an executive order could "begin addressing the urgent need to improve the cybersecurity capabilities of the nation's critical infrastructure."

In particular, the release said the legislative effort to pass the Cybersecurity Act advanced the case for "a voluntary system for owners of key power, transportation and communication facilities to coordinate with the federal government on the strengthening of their cyber defenses."

The letter to President Obama states, "the failure of Congress to act should not prevent the executive branch from taking available steps to counter the enormous and growing cyber threat," and acknowledged, "We recognize that an order directing the promulgation of voluntary standards cannot and should not be the final word in cybersecurity ... A well-crafted set of voluntary standards could, however, be an important step towards improving the cybersecurity of our nation's critical infrastructure."

The letter also affirms the senators' commitment to work toward passing a Cybersecurity Act in Congress.

Surveillance cabling cited in Seattle schools' financial scandal

A report in the Seattle Times says that a previously uncovered alleged financial scandal within Seattle's public-school system may be wider than previously believed, and points to surveillance-cabling projects as examples of the alleged corruption.

Seattle Times education reporter Linda Shaw writes that the scandal "may be $1.3 million more than previously thought," citing state auditors. She also writes, "In one instance, the auditor found, the district paid $14,505 for video surveillance cabling and conduit which auditors estimated was worth $1,054." (See her full report here.)

Shaw reports on other examples of alleged overpayments, including "$127,981 for security equipment at several schools and a district warehouse that auditors said doesn't work or is not fully functional," and "$2,500 for two security cameras at Cleveland High that were not installed at the school."

The installer of the security cabling and/or equipment is among 14 of 26 vendors with whom auditors found problems upon further investigating the original scandalous claims. None of the 14 vendors were named in the auditors' report, but according to Shaw, the problematic dealings with these vendors included "wages paid at much higher than the prevailing rate, lack of detail about what the district was paying for, charges for hours that vendors could not document, and adding what auditors considered excessive markups."

The probe focuses on Silas Potter Jr., a former administrator in the school system. Shaw reports, "It was not immediately clear whether any of the vendors could face criminal charges."

I have a feeling that somewhere in the Seattle area, there's a knot in the pit of some contractor's stomach.

Substandard cable, the steroid era and sour milk

In case you're wondering - yes, I did notice. Just a few days after we covered the latest round of testing the CCCA commissioned on 'no-name-brand' twisted-pair cables, we also ran a story about an upcoming price increase on the materials that are used to make the outside jackets of communications, electrical and other cables. The relationship between the two stories cannot be overlooked.

I know it's the fluorinated ethylene propylene (FEP) insulation around the copper conductors of a twisted-pair cable that has the most (almost everything, really) to do with whether or not the cable will pass the flame-spread and smoke-generation tests that determine a plenum rating. The material that is used on the cable's outer jacket is a lesser factor in that regard.

But there's a larger theme at work. We've reported on it before as the price of copper cable has vacillated. When the price of plenum-rated copper cables in particular peaks, it's often because of the "triple whammy" - when costs of copper (for conductors), FEP (for conductor insulants) and petroleum-based products (for cable jackets) all climb. Of the three materials, FEP is the most significant factor in the ultimate price the consumer pays for the cable. But they all play a role.

That's why the two stories are related. Even though the cost of the jacketing material is not the single biggest contributor to the price of a twisted-pair copper cable, the reality is that any cost increase for any cable material can serve to remind us why the influx of substandard cable does not appear to have subsided. Manufacturing cable is a business of tight tolerances and low margins. It is easy - too easy - for an unscrupulous party to cheat and offer cable at a significantly lower price than those that stay above board. For many purchasers, cabling contractors and end-users alike, it is too tempting to go with the cheaper option and not want to know the truth about what's in the cable. We've told you about copper-clad aluminum cable making its way into the market. As we've shown, such a cable can be detected easily enough by visual inspection.

But how will anyone ever know if the material compounds used to create the cable jacket, or the conductor insulators, really are the types and amounts required to achieve the riser or plenum rating that is claimed? In an overwhelming majority of cases, once a cabling system is installed it is tested to ensure its electrical-performance specifications meet or exceed those established in industry standards. No such testing takes place to ensure the cable meets riser or plenum flame- and smoke-performance requirements. All consumers of cable have to go on are the markings on a package/box/reel of a cable and/or the markings on the cable jacket. If it says CMP, it goes into a building's plenum space. Where I come from (up here in the puritanical northeastern part of the United States) we call that the honor system. Also where I come from, we're seeing examples all the time of that system's failings. Even the prestigious learning institution Harvard University is not immune, we're finding out.

As a sports fan I cannot help but make the analogy to Major League Baseball's steroid era. Everybody involved ignored the problem for years. When some very public admissions/accusations by well-known former players forced everyone's collective head out of the sand, the battle began over whether or not to test players for performance-enhancing drugs (PEDs). I suspect I'm like a lot of fans in that what frustrated me more than anything else during that debate was the notion that there were some clean players who banded together with the cheaters, unified against the idea of PED testing. I couldn't understand it. And I also couldn't fathom (and honestly, still cannot bring myself to believe) that there were no clean players at all.

Switching back from the sports world's performance-enhancing substances to our industry's performance-degrading substances, I read with great interest CCCA executive director Frank Peri's statement: "The CCCA has taken the position that this serious problem will not go away until quality assurance procedures include testing of samples of finished cable procured directly from the marketplace." In other words, it's not going to be good enough for a cable manufacturer to send its "golden reel" of cable - one (perhaps the only one) that it produced above board - to be tested, then once a certain rating is achieved, use substandard materials in the product produced thereafter. That's like testing baseball players for PEDs in spring training then letting them juice up all season. But that's not how it's done in baseball. Just ask Melky Cabrera or Bartolo Colon. (Or ask Brian Cashman.) And that's not how it should be done with cable either.

There is one "minor detail" in this perfect-world scenario, in which test labs shop for cable the same way you do and test what they buy to see if it's on the up-and-up. That is, these testing programs are not free. And to implement them the way I'd like to see, they would not be even close to inexpensive. So am I really suggesting that we pile further costs on cable manufacturers who already are in fierce competition with each other and who face substantial price pressures from their customers? It sounds like I am. But wouldn't these added costs have to be passed on to cable purchasers, further widening the gap between the cost of a cable from an above-board manufacturer and one from a cheater? Unfortunately, the way I see it, yes. It would. If this problem was easy to solve, it would have been solved long ago. But it's not easy. And I have the luxury of sitting at my desk up here in my ivory tower, using my keyboard (and hopefully at least a little bit of my brain) to spout off about the way things ought to be. Easy for me to say what should happen. Very, very difficult for it to actually happen.

So rather than being someone who only curses the darkness, here's my attempt to light a candle. And if I can take that analogy one step further, in much the same way a candle turns darkness into the visible, how about some enhanced visibility into the "freshness" of a cable manufacturer's testing program? Another recent bit of news from the CCCA, in conjunction with Underwriters Laboratories, was the release of a mobile app that can help users identify suspect cable as legit or not. Among the features of that mobile app is access to UL's online certifications directory, where users can verify that the cable they're looking at is in fact certified by UL. As far as I can tell, that directory is the deepest visibility there is into the extent to which a cable actually has met the performances it claims. Wouldn't it be reassuring if other test agencies developed this depth of visibility? Furthermore, I think it would be helpful for the end customer to know just how recently any brand of cable passed performance testing, based of course on a random sample taken from the supply chain. I'm envisioning some cross between the "born-on date" initiated by Anheuser-Busch for its beers, and the signs we see inside industrial facilities that count up the number of days that operations have carried on without a workplace accident. The information could state the most recent date on which a sample was purchased that passed the required tests, along with pertinent information about the sample used. Whether this information would exist in a central database accessible to cable customers, on cable manufacturers' websites, some combination thereof, or wherever, I don't see how it could be anything but an asset to the industry as a whole.

And assets don't just materialize out of nowhere. They require investment. That brings us back to, "This would be a costly endeavor, which would actually increase the price of cable and further tempt users to go with a lower-priced, illegitimate alternative." All I can really say to that is that my mythical "cable-sample-passed-the-tests-on-this-date" information has to become the equivalent of the date stamped onto a carton of milk. By that I mean, nobody buys the product without such a date. Imagine even seeing a gallon of milk without an expiration date on it, much less buying one. Even if I'm in a supermarket where I've shopped for years and I have a level of trust in that retailer, and even if the brand of milk is one that I consume regularly, I'm not going to purchase a gallon without a date on it. And I'm certainly not going to walk into a store I haven't been in before, see a container without a brand name that says only "MILK" (or, even worse, "MLIK"), notice that the container has no date on it at all - then buy that milk and give it to my family.

As an industry, it is evident that we have a long, long way to go before some users are unwilling to purchase the cable equivalent of undated milk. But I maintain both optimism and confidence that we do not face the situation Major League Baseball did, in which the cheaters were the popular superstars exhibiting the best performance and resisting a rigorous testing platform. As a baseball fan up here in the puritanical Northeast, I have had my ups and downs cheering for the Boston Red Sox. But one person I remember distinctly, and admire, from the steroid era was a fourth outfielder named Gabe Kapler. He looked like a bodybuilder and was exactly the player some would point to and say, "It's obvious these guys are on steroids." But every time he was asked, Kapler made his stance clear, in contrast to the MLBPA as a whole. Kapler would say (and I'm paraphrasing), "Test me right now. Test us all. I'm clean and have nothing to hide." He wanted to compete, literally and figuratively, on a level playing field with others who were doing their jobs above board. If all the players in our industry truly embrace that attitude, with nothing to hide and eagerness to verify their clean records, we'll all be better off.

I'll drink a glass of fresh milk to that anytime.
