Top 5 Fiber and Cable Cleaning Tips from the Experts

Let’s face it. Spring cleaning stinks. I mean, does anyone actually enjoy cleaning? I don’t know about you, but I certainly am not counting down my winter days until I can scrub the house top to bottom only to have it quickly soiled by muddy feet and paws, beach sand, cut grass and whatever else wanders in with the warmer weather.

But dirt happens. And while cleaning may not be a barrel of fun, there is always some sense of satisfaction when it’s done and everything is looking its best.

Where Will I Testing Cat 8 Cabling Systems with Cable Tester

By now you probably know that Category 8 cabling was approved by the TIA TR-42.7 Copper Cabling Subcommittee, and maybe you've even heard that Fluke Networks introduced the DSX-8000 CableAnalyzer, the first field tester independently verified and endorsed to meet all of the requirements for the Cat 8 field testing standard.

What’s the Deal with OM5 Cable Standards – WBMMF?

Guest Posting from Corning Optical Communications

OM5, previously known as wide band multimode fiber or WB MMF, has been quite the hot-button topic as the standards have been widely debated and are now finally concrete.

So what is OM5 exactly? Most simply, it’s a version of the OM4 fiber with additional bandwidth characterization at 953 nm.

Pros and Cons of Bend Insensitive Multimode Fiber

Lately, I have been getting questions about why bend insensitive multimode fiber (BIMMF) can’t be used in test cords. The argument is that non-BIMMF (e.g., “traditional” fiber) is becoming more difficult to procure and installers need the flexibility to buy something off the shelf. Additionally, requests are being made to change one IEC testing standard to not mandate the use of non-BIMMF in test cords. Let’s examine this closer and explore the consequences.

Simplify the Complexity of Fiber Certification with TRC

No, not what Deedee would ask Dexter in his lab, what does that button do on the bottom of the FI-1000 video inspection camera? It turns out it has a really helpful function that I want to share with you here.

Benefits of Fiber Optic and Passive Optical LAN Test

In recent years, passive optical LANs have gained significant popularity as an alternative to horizontal copper structured cabling in a variety of enterprise spaces.

The technology brings fiber out of the riser backbone and data center, and with that comes the need for fiber technicians to test these systems out in the horizontal space.

Let’s take a closer look at these passive optical deployments.

How Do They Work?

Как высокоскоростные оптоволоконные приложения влияют на сетевое окружение

In last week’s blog, we took a Closer Look at 40 Gig Duplex Multimode Applications, just one of the many ways that today’s data centers are cost-effectively achieving increased bandwidth in switch-to-switch fiber links. And when we say many ways, we literally mean many.

Более подробное рассмотрение 40многорежимных приложений Gig Duplex

 

There’s been a lot of talk in the industry surrounding solutions capable of running 40 Gig Ethernet over duplex multimode fiber—especially with OM5 wideband multimode fiber (WBMMF) now recognized within industry standards that specifies wavelengths between 840 and 953 nanometers to support wave division multiplexing (WDM).

Testing Cabling With MPO Connectors – What’s New?

With the wide variety of standards relating to fiber optic cabling, the absence of published standards for testing fiber optic cabling terminated with MPO connectors might come as a surprise. Finally, a technical report (TR), written by this author, is scheduled for a June 2017 publication that provides such testing guidance - it is TR/IEC 61282-15. A technical report provides guidance on a subject but does not have requirements (e.g. no “shalls”) as an international standard or an ANSI/TIA standard would.

Что за шумиха вокруг сертификации кабельных соединений ограниченной мощности?

 

You maybe have heard the recent buzz about LP-certified cable for power over Ethernet (PoE) applications and be wondering if you need this cable for your PoE installations. Let’s take a closer look at this new UL certification, its relationship to the 2017 National Electric Code, why it was introduced and why you still need to test.
