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 […]

 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 […]

VIAVI is back at the SCTE/ISE Cable-Tec Expo this year with exciting news! We expanded our cable portfolio with our recent acquisition of Trilithic, so be sure to come see it all in VIAVI Booth #1387 and Trilithic Booth #153. And while you’re stopping by, be sure to check out the new FiberChek Sidewinder MPO inspection scope. […]

Migrating to G.fast is the most economical way to bring Gigabit speeds to customers because the existing copper or coax infrastructure is reused between the DPU to the customer’s client. This avoids rewiring for the last 250 to 300 meters. All segments of the hybrid network: fiber, copper line, interior twisted pair or coax wiring, […]

Migrating to DOCSIS 3.1 doesn’t have to be complicated. With these five points, you can become an expert in no time! OFDM building blocks are the key to optimal performance, reliability, and quality of experience for the customer: • Test the OFDM signal quality, including levels and level variation, MER, and ingress/noise under the carrier. […]

It goes without saying that the relentless customer demand for faster broadband speeds is a double-edged sword for cable operators. It keeps all of us in this industry employed, but at the same time presents challenges to the way that things have always been done to deliver this service to our customers. Our old tricks […]
