32 TEST & MEASUREMENT Cable certifiers what really matters? By Dan Barrera, Global Product Manager, IDEAL Networks www.idealnetworks.net Over the past two years, we’ve conducted extensive research with cable installation companies in both the US and Europe, observing how they work when certifying cable installations and conducting more than 60 hours of in-depth interviews to delve into the specific challenges they face when using their certifiers. Here, we will look at some of our key findings around cable certifier usage trends. Topline takeaways A core part of the research investigated what cable installers consider to be most critical when choosing a certifier. It identified that durability is the factor that the market deemed most important by far, followed by the ability to set up tests simply, and having an accurate and easy to use fault finder. We also measured how the currently available certification solutions performed against the customer outcomes identified. To do this, we tested all the devices on the market with the most common test methods requested by customers. In each scenario, the tester’s performance was benchmarked against the customers’ average expectation. Our investigations also looked at which areas users felt performed worst regarding the capabilities of cable certifiers and found there were several areas with potentially concerning market satisfaction gaps. The largest concerned labelling results transfer and management software. This was closely followed by fault-finding – a potential worry for manufacturers as this was picked out as one of the most critical elements of a cable certifier to users. The industry’s requirements around fault-finding were expanded on as part of IDEAL Networks’ more in-depth research and product investigations. IDEAL Networks shares its research into the challenges that end users face when using cable certifiers Minimise fault-finding time and improve accuracy Good cable installations tested with a correctly configured tester shouldn’t have many faults. However, when faults do occur, it’s important that they’re fixed quickly. Installers simply don’t have the time to spend reviewing measurements on the certifier to understand, and then fix, the failure – they don’t want complexity in this area. Instead, they are demanding products which show the type of fault, what has caused it and most importantly, where along the cable they need to go to fix it. Simple test set-up A need for simplicity was also expressed when it comes to set-up, in order to test the installation. During our research, we found that technicians may make hundreds of inputs on average for set-up. This includes typing the address and labels, selecting standards, moving between functions and configurations. This always happens at the end of the project when the pressure is on and there’s simply no time to absorb delays. Complex certifier set-up can take a lot of time, as well as leading to mistakes – many standards are similar so, in a rushed situation, it can be easy to choose the wrong one. Incorrect set-up can also lead to failed links which cause engineers to spend time fixing issues by re-terminating or pulling a new cable in the hope it will pass and resolve the problem, even though the problem will persist. On some occasions, installers may also encounter problems by mistakenly selecting a lower standard, like Cat 5e rather than Cat 6A. While the installation will test without problems, when the results are submitted for warranty, they will not be eligible.
