DWDM is moving into access networks at a higher rate than ever before. This includes cable service providers upgrading to the newer distributed access architecture (DAA), both cable and traditional telecom service providers to deliver business services, and wireless service providers as part of their centralized RAN (C-RAN) approach as well as a key part […]
As we know, the demand for broadband services is on the rise and demand is not restricted to towns and cities. Folks living in rural locations need good-quality, high-speed services just as much as their urban cousins. For the majority of cases, especially greenfield sites with no existing infrastructure, Passive Optical Networks (PON) and Fiber-to-the-Home […]
Fiber is being pushed deeper and deeper into access networks worldwide as service providers continue to address subscriber demands for higher capacity services. Going “fiber deep” could be part of G.fast deployments for telco operators or Distributed Access Architecture (DAA) upgrades for cable companies, but the next step (or end step) is full fiber-to-the-premise (FTTP) […]
There are any number of things you can point to that demonstrate what is driving growth in fiber deployment, regional FTTH/PON initiatives, national high-speed broadband growth, core network 100/400G upgrades, or preparation for new services such as 5G. One thing that is critical for these new or upgraded services to function to their peak and […]
Simplifying high-density fiber cable certification The rise in fiber adoption by service providers is great for those who manufacture the cables, but it’s causing a headache for many who have to commission it. More and more, higher fiber-count cables are being laid, leading to a challenge for installers and contractors: how to manage, track and […]
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 […]
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 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 […]
