It’s That Time of Year Again – Beware of Ghosts and Dead Zones!

There’s a chill in the air, leaves are falling and it’s time for all things spooky. So we thought that in the spirit of Halloween, we would post this blog again that takes a look at two of the most confusing (and perhaps scariest) OTDR events--ghosts and dead zones.

Type 3 and Type 4 are Here!

Last week the IEEE 802.3bt standard for Type 3 and Type 4 PoE was finally ratified! While we’ve been talking about these higher levels of PoE for quite some time, now that they are finally an approved standard, we thought it was a good time to clear the air on PoE types, classes, and certification, as well as provide a refresher on our specialty—testing.

Mixed Mindfulness

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.

An Industry of Innovators

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.

The A-B-C’s of Fiber Polarity

Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, it's The A-B-C’s of Fiber Polarity

To properly send data via light signals, a fiber optic link’s transmit signal (Tx) at one end of the cable must match the corresponding receiver (Rx) at the other end.

While this seems obvious, polarity is one area that seems to cause the most confusion among technicians. So let’s break it down and start at the beginning.

Plenty to Learn (and CECs too) at Next Week’s BICSI Fall Conference & Exhibition

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).

Wire Map Testing: It’s Not All About Color

A wire map test may seem like the most basic test for copper network cabling and therefore one of the least important, but 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 Road to 200 & 400 Gig is Already Paved (and Traveled)

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).
