The IEC recently published the first standard for field testing of MPO installations. IEC 61280-4-5 fills a gap in standards by providing clear guidance for how to test MPO systems of various configurations. For some time, VIAVI has made clear statements that existing standards such as IEC 61280-4-1 and 4-2 apply to simplex and duplex […]
Where’s the problem? The basic function of a TDR is to test a cable to either verify its length and quality, or to identify points in the cable that are causing problems. Traditionally the user would look at the trace, in which reflections are indicated by positive or negative deviations, and place a marker on […]
There are various ways to which 5G mobile networks can improve the way we live – yet, they are framed as a luxury rather than a necessity. These networks produce faster speeds and lower latency that facilitates ultra-high definition video streaming, which are typically perceived as a means to enhance smartphone and gaming experience. However, […]
Pluggable coherent optics offer advantages in many areas. One of the biggest factors is electronic dispersion compensation. For DCI, traditional ‘direct detect’ systems needed a detailed pre-planned link with dispersion compensation ‘engineered in’. This is both expensive and challenging to deploy. Scaling and maintaining are complicated. Electronic dispersion compensation inside the DSP of coherent modules […]
5G aims to provide gigabits of throughput, highly reliable low latency connections for industrial automation and other time sensitive applications. To deliver, however, 5G networks require ubiquitous and seamless 5G coverage. The big challenge is the availability and the type of RF spectrum. 5G standards, starting from release 15, support spectrums both in the sub-six […]
In the first half of 2020, IT teams around the globe rapidly responded to unprecedented change, threw the rule book out the window (in many cases), and found innovative and in some cases unorthodox ways to keep the business running while transitioning into some ill-defined “new normal”. This upheaval created opportunities that cybercriminals were eager […]
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 […]
The deployment of the 5G network is a complex process. There are layers of complexity to it, each intertwined with the next, which makes it essential for service providers to understand the implications of every decision. Here are four main challenges that network operators will need to overcome for a successful 5G deployment. […]
“We will be able to achieve new levels of operational automation, flexibility and adaptability.” This is how Verizon described the networks of the future. Or, to be more specific, this is how the company described its new cloud-native 5G core network, which it says will be launched in 2021. The quote isn’t just a salesy […]
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 […]
