OTDR, What does it do?

Optical Time Domain Reflectometers (OTDRs) and fault locators are used to certify new fiber installations and locate faults in deployed fiber optic networks.

OTDR

OTDRs:

  • Scan and characterize fiber optic networks (from one end of the fiber).
  • Display characterized fiber either as a trace showing optical loss and reflectance vs. distance or as a LinkMap providing an icon-based representation of the fiber sections, splices, connectors and any detected faults (breaks or macro-bends).
  • Provide link summary information (end-to-end length, loss, optical return loss).
  • Provide details for each detected connector, splice or fault including event location, event type, loss and reflectance at event and loss to event.

Let’s get a good look at one of the AFL models from their YouTube channel.

OTDRs and fault locators are available for both multi-mode and single-mode networks including passive optical networks (PONs) supporting a range of performance requirements and budgets.

For more information on selecting the proper OTDR check out the AFL selection guide. Once you have a model selected contact your Authorized AFL Distributor Discount-Low-Voltage.com for pricing and availability.

Need Fiber for Security Cameras?

Fiber Optic Media Converters like the Signamax 065-1196A series, are the economical bridge between a copper infrastructure and an optical fiber run.  Even in smaller security networks the obstacle to reach distances greater than 100 meters will require an extension over fiber.
Fiber Camera Layout
Imagine a property with a copper-based network that has decided to increase their security parameters by installing additional cameras.  The additional coverage could be around the parking lot, a multi-story building, or maybe the property has multiple structures that will require extended data transmissions.  Once the copper-base recommended distance is breached between the cameras and the network video recorder, the transmission will typically work intermittently or not at all. To ensure the investment meets its intentions a span of optical fiber with the existing copper-base will allow a more reliable transmission for the extended span by decreasing the electromagnetic interference between the cameras and the NVR.

Charging Station for all your Tablets!

I don’t know about the rest of you, but growing up, my school bag primarily consisted of folders, highlighters, the occasional glue stick, and of course the staple items – pens, pencils, and paper. And at the end of the day, the items we didn’t need to take home would simply be stored in our desks. Open, non-locking desks…because who would really go in and steal someone’s pencil?

But technological advancements have made it so pens and paper are no longer staples in the classroom of any grade level. These school items have been replaced with electronic tablets and laptops. Now these items are quite valuable and definitely prone to theft…so we wouldn’t recommend you or your students leaving these expensive items just in a desk overnight. Instead, store and charge all of these devices in a secure, locking cabinet. And you guessed correctly; we have just the cabinet in mind!

Our new Wall Mount Charging Station is the perfect accessory to any classroom, education center or college campus. It can hold anywhere between eight and 12 tablets or laptops, depending on size and orientation. With its 6.5” depth, the cabinet hugs nicely against the wall and is one of the only thin wall mountable charging stations on the market. It doesn’t take up much space so regardless of your room size, finding a spot for this cabinet won’t be hard.

charging station

What all do you get with the Wall Mount Charging Station? Good question – you get an A! The cabinet includes four shelves for storing devices. Each shelf has slots for cables to feed down through the cabinet and plug into the included 8 Outlet Power Strip, stored in the bottom enclosure. Now we know there could be more than 12 cables running up and down in this cabinet and the last thing we’d want is for these cables to become intertwined with one another. (Talk about an extra hassle for teachers and professors to deal with…so let’s just avoid that!) To help solve this issue, nine Adhesive Backed Cable Holders come included, but not pre-installed, with the Wall Mount Charging Station. During the installation of your charging cabinet, you can choose the placement for these self-sticking holders based on your tablet charging needs. The “mouth” on each cable holder keeps cables in place – whether or not a device is being charged at that time. Sounds pretty slick, right?

Well, we’re not done yet. We have a few more qualities about this charging station that will make teachers want to get out their “Wow,” “Way to go,” and “Awesome job” stickers. For instance, the Wall Mount Charging Station is made out of aluminum so it’s lightweight and easy to install. Plus, you don’t have to worry about your devices overheating because vented slots can be found all throughout the cabinet to promote air flow around the devices. You also don’t have to worry about damaging the devices or scratching the screens because each shelf is lined with rubber and foam strips.

Alright, we’ve finally reached the quality that makes the Wall Mount Charging Station head of the class. With each new school year comes new teachers, students, curriculum, and likely new electronic devices. But don’t worry; you don’t have to switch out your cabinet! It was designed to last evolving technology and adapt to new charging styles. It is not proprietary to any brand or charging style, so if charging ports change with newer versions, you can still use this charging station.

Use your smart phone to help test Fiber Optic Cable

Two things are happening in the world that have a significant impact on fiber testing—more than 6 billion smartphone users are expected in the next four years and 400 gigabit per second (Gb/s) data center speeds are expected in the next two years.

The two are clearly related because more devices mean more data and the need for higher bandwidth, resulting in an ever increasing number of fiber links in the data center. But how exactly are they related when it comes to testing those links?

As the most widely used interface, it makes complete sense for your smartphone to become an integral part of an overall fiber testing and inspection solution. It’s rapidly becoming a “must have” rather than a “nice to have.” Leveraging your smartphone can make the task of testing fiber links easier, faster and more efficient—and that means more money in your pocket.

the rouge tester

When it comes to using your smartphone for testing, it’s important to have a good app. A powerful and flexible app that is also uncomplicated can go a long way in minimizing testing challenges without the need for additional training. The right combination of a great app and an advanced fiber test platform offers a myriad benefits. You can easily see your assigned testing project and parameters, view and save live test data as it is collected, and recall and share results via email, text or mobile cloud applications. And by syncing results data to the cloud, you no longer have to save it to a USB drive and risk the chance of lost test data or managers waiting for the information.

As fiber technology continues to evolve and network speeds continue to increase to 40 and 100 gigabit and beyond, fiber optic networks are becoming more sophisticated and more complex than ever before. And that means more stringent performance requirements and greater pressure to ensure proper design and installation. While test and inspection may be a small part of your business, it is essential for ensuring that your fiber optic installation will meet the performance requirements for the application it was intended to support.

Let’s check out the product video from AFL.

At a time when extensive and comprehensive fiber testing is a must, doesn’t it make sense to use a device that you already own and are comfortable using—especially if it helps you get the job done faster and more efficiently to save you time and money?
