Кабельные хроники

Преимущества функций ПО версии 6,0 доступны пользователям новых и находящихся в эксплуатации модулей OptiFiber Pro

You’ve probably heard of the new OptiFiber Pro HDR models we recently introduced, which are designed for OSP and PON applications. However, there are a number of new features now available as part of this launch that work in both the current OptiFiber Pro as well as the new HDR models. In fact, these new features can be added to any existing OptiFiber Pro at no charge through a simple upgrade. Let’s check out these new capabilities.

Новые модули OptiFiber Pro с высоким динамическим диапазоном для тестирования за пределами завода и тестирования пассивных оптических сетей

Дополненное новым оптическим временным рефлектометром Fluke Networks OptiFiber® Pro с расширенным динамическим диапазоном (HDR) решение Versiv может применяться для работы с FTTx-системами и PON-сетями, а также в центрах обработки данных и структурированных кабельных системах с классификацией по категориям. Since Versiv users report that its efficient and familiar interface cuts costs by 65% when testing, certifying and maintaining copper and fiber network installations, it’s clear why they’d want to apply the same savings to outside plant jobs as well.

Опять наступило это время года — остерегайтесь призраков и мертвых зон!

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.

Смешанная внимательность

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.

Индустрия новаторов

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.

Полярность волокон: основы

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.

Много нового (и для CEC тоже) на конференции и выставке BICSI Fall на следующей неделе

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).

Тестирование схемы разводки: дело не в цвете

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.
