When it comes to a cabling infrastructure, not all media and applications are always the same. So for each and every link, it’s important to be aware of what you’re testing—from both a media type and application standpoint.

Last week at the 2018 BICSI Fall Conference in San Antonio, TX, two of Fluke Networks’ solutions were chosen by a panel of top-tier cabling and communications systems specifiers, designers, integrators and managers for making groundbreaking contributions to the structured cabling industry.

At the upcoming BICSI Fall Conference & Exhibition on September 9 – 13 at the Henry B. Gonzáles Convention Center, San Antonio, TX, there are plenty of opportunities to learn about the latest technologies, and Fluke Networks is excited to bring you the latest on testing everything from advanced four-pair PoE to passive optical networks (PONs).

Virtually every Ethernet cable tester can perform a wire map test - likely the most basic test for copper network cabling. Despite being a basic test, it is actually one of the most critical. And while the pair colors of blue, orange, green and brown might help you pass wire map testing, the test itself really doesn’t care about color at all.
Let’s take a closer look.

The increasing demand for higher bandwidth to support Big Data has driven the need for ever-increasing Ethernet speeds, starting with 10 Gig in 2004 to the introduction in 2010 of 40 Gig with 4 fibers transmitting and 4 fibers receiving at 10 Gbps (40GBASE-SR4) and 100 Gig with 10 fibers transmitting and 10 fibers receiving at 10 Gbps (100GBASE-SR10).

Fiber splicing is a method of connecting two fibers, whereby two fibers are precisely cleaved and then aligned and fused using a fusion splicing machine. The fusion of two fibers is achieved by an electric arc that essentially welds the fibers together. A mass fusion splicer welds 12-fiber together at once and is performed using 12-fiber ribbon cable.

It felt like a Monday morning when the call, actually an e-mail, came in. “I think my DSX is broken!” As you know, they are really tough machines and, when it looks like the Fluke is wrong, usually it isn’t.
“What makes you think it is broken?” I asked, “How does this failure manifest itself?”
“The tester is failing links that used to pass.”

Verification of test reference cords is easy, right? Yes, usually…but not always. After the power meter is set to 0 dB via the reference procedure, the loss of a mated connector pair is expected to be less than 0.20 dB for single-mode (e.g., -0.20 dB). Let’s examine one scenario where a loss is not negative (e.g., +0.15 dB).
The typical process for validating the loss of a connector, to verify if it is “reference grade” for example, is as follows:
