Verification testing answers this question. For copper cabling, these simple-to-use, low cost tools perform basic continuity functions such as wire map and toning. Wire mapping will tell you that each pair is connected to the right pins at plugs and jacks with good contacts in the terminations, while toning is used to help identify a specific cable in a bundle or at the remote end. Some verification testers like Fluke Networks' MicroScanner2 Cable Verifier include a Time Domain Reflectometer (TDR) feature to help determine the distance to the end of a cable or a trouble spot. It can also detect if a switch is connected to the cable under test.

To maximize return on investment, your test equipment moves from jobsite to jobsite. At any given moment, several of your skilled technicians can be testing and certifying network cabling with multiple testers for multiple concurrent projects in multiple areas—a real recipe for mixing up and misplacing test equipment. The more testers, the more complex it gets to keep track of them. Misplaced test equipment leads to project delays—something 68% of users say they have experienced. Despite the facts, the majority of installers do not actively manage their test equipment assets or use ad-hoc non-standard systems best, such as manual sign out sheets or Excel spread sheets. And yes, there are some installers that still use a peg board to keep track of who has a tester.
Since cables are the most expensive equipment in an installation, they must be thoroughly tested using the methods listed above. This setup is just with two-wire continuity tests and may be used throughout the switching matrix.

For professional contractors and installers of data communications cabling systems, compliance with ANSI/TIA 606-B Standards updated back in 2012 has required new levels of precision in cable labeling – often an arduous and time-consuming process for cable installers. Today, however, thanks to smart, cutting-edge cable labeling tools and technologies, that situation has improved dramatically!
It is vital to test a new network cable after the installation with cable trying out tools. Many matters can go wrong at some point of the installation procedure which include cables being broken, insulation can destroy and connections might not be nicely terminated. In addition, electric disturbance and environmental additives also can affect network execution.

You’ve just finished a copper cabling installation for a customer, your DSX-5000 CableAnalyzer is properly configured and you’re ready to start testing. With a press of the “TEST” button, you’re off and running. Link after link, the tester displays a “Pass” and you’re feeling really good about the quality workmanship of your installation. All of the sudden, a “Fail” pops up on the screen and you’re forced to stop dead in your tracks. You know that all links must pass before the manufacturer will issue the warranty—and likely before you get paid for the job. Quickly isolating and repairing the problem can make all the difference in getting on with the business of warranting the installation, ensuring customer satisfaction and making money. Thankfully you have the powerful troubleshooting capabilities of the DSX-5000 in the palm of your hand.

A key aspect of the growing number of devices connected to the LAN is the ability to power those devices with evolving PoE technology. With IEEE 802.3bt PoE standards expected to be ratified next year, we will soon be looking at Type 3 PoW at 60W and Type 4 PoE at 90W delivered over all four pairs. While Cisco's UPOE already delivers 60W, next year's ratified PoE standards will open up the door for more PoE-enabled devices than ever before. That combined with power over HDBASE-T (covered in this earlier blog) that delivers up to 100W of DC power in conjunction with video signals paves the way for PoE LED lighting, LED TVs, digital signage and more.

While probably one the least talked about standards, and one that is often considered voluntary, the TIA-606-B labeling standard exists for a reason. An unlabeled infrastructure results in an unmanageable mess that ultimately makes every reconfiguration and troubleshooting task a time-consuming, frustrating and costly tracing game of hunt and peck. Despite the fact that it is an industry best practice, labeling takes time--especially if you're manually creating identifiers for every outlet, every cable, and every patch panel port and managing them in a separate database. So however the essential task of labeling can be accomplished faster, more efficiently and with improved accuracy, the end result is savings.
Certifying a cabling installation doesn't mean anything without the burden of proof. Documenting the results is the only real way to ensure installation accountability and integrity, resolve disputes and facilitate more efficient troubleshooting. Even if the customer or a manufacturer's warranty doesn't require documented test results, documentation is still a best practice and your best protection. If you certify a cabling installation that later fails and you don't have the documentation to prove it, how else do you provide evidence that the cable was functioning properly and that it met the specification when you were done with the job?

So you came across some Category 6 cable available online for practically half what you've been paying for that brand name. It claims TIA-568-C compliance, includes the UL listing mark and even has a ETL verification legend printed right on the cable. Before you get too excited, you might want to make sure that cable isn't made with copper clad aluminum (CCA). Less expensive than using solid copper, cables made with CCA conductors are simply not worth the risk. Not only are they non-standards compliant, but they often do not have a valid UL safety listing per the National Electric Code(NEC)

If you're at all familiar with copper cable, you've probably heard about crosstalk--the phenomenon by which a signal transmitted on one pair or one channel creates an undesired affect on another pair or channel. Crosstalk causes interference on an affected pair of conductors or overall cable creates errors or prevents data transmission. For example, have you ever heard someone else's conversation while on the phone? This is caused by interference between adjacent telephone wires. But are you aware of the difference between the near end and far end crosstalk parameters you need to test for in balanced copper network cabling systems? As part of our Cable Testing 101 series, we thought it would be prudent to take a closer look.
The global fiber optic connectors and cables market size reached USD 5.72 Billion in 2022 and is expected to register a revenue CAGR of 9.2% during the forecast period, according to latest analysis by Emergen Research. Growing demand for digital communication and data is one of the key factors driving revenue growth of the fiber optic connectors and cables market. A surge in the number of data center facilities and high demand for Fiber To The Home (FTTH) are a few of the major factors further contributing to revenue growth of the market. Fiber optic cables are becoming increasingly popular owing to scalability and cost-effectiveness.
With the need for increased speed and power over Ethernet (PoE) being addressed within IEEE standards, work within TIA must follow suit as the two standards bodies work hand in hand to ensure that the applications put forth by IEEE can be adequately supported by the cabling infrastructure. Let's take a look at some of the recent and most significant standards activity within the Subcommittee and how they relate to standards development happening within IEEE.
