Оптический рефлектометр (OTDR): комплексное средство устранения неполадок

So you’ve finished your fiber cable installation and are now on to the task of certifying the cable plant using an optical loss test set (OLTS) – it’s the tool you need for Tier 1 certification and the most accurate for measuring loss to ensure application support.

Unfortunately, you find some critical fiber links that far exceed your loss budget for the application. You now need to troubleshoot those links so you can fix the problems and move on to your next job. And the faster you can locate the problems, the faster you can fix them.

Есть ли царапины на торцевой поверхности волокна?

While it seems we can never hammer home enough the need to properly clean and inspect fiber end-faces since contamination remains the number one cause of fiber link failures, have you ever thought about what exactly you are cleaning and inspecting?

Обзор BICSI: 3 самых популярных вопроса

It’s always interesting at trade shows to learn what’s on the minds of end users, designers and technicians alike when it comes to testing. And this year’s BICSI Winter Conference was no different.

Узнайте целевой уровень потерь SYSTIMAX заранее!

We’ve covered fiber insertion loss in plenty of past blogs, so by now we hope that you know it’s the amount of signal loss that occurs as the signal travels along a cable link. We also hope you know that insertion loss is directly related to the length of the cable—the longer the cable, the greater the loss—and that any connection point along the way (connectors, splices, splitters, etc.) also adds to the loss.

Получите 3 CEC на семинаре перед конференцией BICSI, посвященному тестированию высокоскоростных оптоволоконных каналов

High speed applications are driving the deployment of multifiber MPO/MTP architectures in the data center, and it’s not just cloud and hyperscale data centers that are deploying these solutions. As the de facto interface for 40 Gig and 100 Gig switch-to-switch backbone data center applications that use parallel optics, MPO/MTP links are rapidly becoming commonplace in today’s enterprise data centers.

Просмотр нашей презентации о тестировании пассивных оптических сетей (PON) на конференции BICSI

A passive optical LAN, also sometimes referred to as simply a passive optical network (PON), is a point-to-multipoint architecture that used passive optical splitters to split optical transmission signals from a single strand of singlemode fiber into multiple outputs. The technology has gained wide acceptance in outside plant applications, and it is now gaining traction in premise applications—especially in government and hospitality markets.

2018 — новый поворот в революции Интернета вещей

At this time of year, every industry tends to reflect on the past twelve months and make predictions about what 2018 will bring – it’s just what we do. So why should this year be any different?

Некоторые из наших любимых блогов

In the spirit of the season and that “Sound of Music” favorite by Julie Andrews (that some have dubbed a holiday classic), we thought we’d take a moment to wish everyone Happy Holidays and Best Wishes for a Prosperous New Year and share with you a recap of some of this years’ favorite Cabling Chronicles (yes, it is sung to the tune of “My Favorite Things.”)

CPR — не такой уж и нелепый норматив

There’s no doubt that the European Union has a lot of rules and regulations—something frequently pointed out by those who campaigned for a Brexit vote in the United Kingdom. And many joke about some of the more ridiculous ones, like the law that prohibits people from eating pet horses, or the one that prohibits manufacturers of bottled water from labels suggesting that consumption could fight dehydration. (Since when didn’t water fight dehydration?)

Устранение неполадок сращиваемых соединений

A fusion splice is when two fibers are fused together using an electric arc. Often used with pigtails for connecting 250-micron outside plant fiber to 900-micron inside plant fiber at the building entrance, fusion splicing is achieved with a fusion splicing machine after the fiber is properly cleaved with a precision cleaver. Fusion splicing can be done for a single fiber or for 12-fiber ribbon cable via mass fusion splicing that splices all 12 fibers at once.
