5G

This is the first in a 3-part blog series. Timing & Synchronization If someone played a word association game on the topic of mobile telecommunications technology, the first things to come to mind would likely be cell towers, satellites, antennas, and of course smart phones. Most people, even in the industry, would never think of […]

Viavi fiber Test

This is the fourth post in a series on Smart Fiber Testing – see links to previous posts below. Reduce fiber test and certification times for FTTx/PON, Access, and Metro deployments As more fiber networks are planned for deployment, providers are seeking ways to make fiber installation and maintenance more effective and efficient. In our […]

5G Fronthaul

This is the fourth in a series of blog posts on the Evolution of Fronthaul, links to other posts below. As wireless operators announce their plans for the introduction of 5G services, ecosystem players are developing and introducing a new range of capabilities to pave the way for a smooth transition from 4G to 5G. […]

VIAVI

When you look at this image, do you see a chalice? Do you see two men in profile? Now that I’ve mentioned both images, can you see both images at once? Fiber testing can be like this trick, you have to be able to see more than what is obviously in front of you. In […]

FTTH-PON Q and A

Our recent webinar with Light Reading, Lessons Learned: Efficient Deployment & Maintenance of FTTH/PON Networks, garnered several questions from the attendees. We thought that even those who may not have caught the live webinar might benefit from this Q&A. If you’d like to see the webinar recording, please visit the Light Reading Testapedia page.  Q. Is […]

OTDR Test

How can you improve event detection with your OTDR tests? Ever wondered why your OTDR isn’t reliably accurate in detecting all the events on your fiber under test? One reason is that there isn’t just one test configuration that is optimal to characterize a link with a single OTDR shot. If you use an OTDR […]

Simplify FTTH/PON Testing with “Smart” Fiber Features The rise in fiber adoption by service providers is fueling the demand for workers who can skillfully build and certify fiber plants, especially for deployment of Fiber to the Home (FTTH). This means that installers and contractors, who are traditionally trained in copper or coax network installation, must […]

Part 3 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 2: Fiber Deployment in Wireless) In parts 1 and 2, I described the overall radio access network architecture and best practices for deployment at physical layer which is primarily fiber for the links between the base band unit (BBU) […]

 This is a re-post of an article in Gazettabyte, © Roy Rubenstein 2017 The race is on to deliver 400-gigabit optical interfaces in time for the next-generation of data centre switches expected in late 2018. The industry largely agrees that a four-wavelength 400-gigabit optical interface is most desirable yet alternative designs are also being developed. Optical […]

cellular towers

Part 2 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 3: CPRI ) As we learned in part 1, fiber deployment permits the placement of RRH’s closer to the antenna. Also known as light radio, this RRH placement has significantly improved the energy efficiency of cellular networks as the […]
