Correct Fiber Cleaning Critical to 5G Success

To provide the kind of faultless multi-gigabyte service promised by 5G, the fibre used in networks must be properly installed and maintained correctly. Therefore, it is important to address the need for the effective training of technicians. The deployment of 5G networks will only be successful if a skilled workforce is created who understand the correct way in which to carry out all of the processes.

Notes From an Autodidact: What I’m Learning About Fiber Optics Now

Last month, I wrote about how a newcomer could get started in fiber optics and learn the basics. What if you are already experienced in fiber optics and want to keep up with new technology? I can empathize with you. I have been in this industry a long time and have seen many changes. I learn new things often. To continue writing about fiber optics and creating technical references for others, I have to work hard to keep up.

Photonic integration and co-packaging: Design tools for footprint optimization in data center networks

As traffic within and between data centers continues to grow, operators need to constrain the resulting increase in power consumption to minimize operational costs. This is driving the need to manage footprint and power at the system design level. Photonic integration and co-packaging are related approaches to addressing area and power challenges for networking applications. These component-level design options will enable future footprint-optimized solutions for data centers.

Data center planning

Data centers are the control hubs of businesses and organizations. Complex architectures and operating workflows, as well as a range of different applications, all pose a challenge for the network infrastructure. The quality requirements that are placed on structured, application-neutral cabling are correspondingly high. Individualized planning and a high level of automatic cable management play an important role. Transmission paths and attenuation budgets must be considered right from the start in the design of a modern data center. This is because efficient cabling forms the basis for the trouble-free operation of all the processes and this factor must therefore be taken into account during the data center planning phase.

Cabling Mistakes #9: Rely on Duplex Tester for MPO Cable Certification

Let’s take a look at the #9 Dumb Thing that smart people do when testing network cabling systems—relying on a duplex tester for certifying MPO trunks. Field testing is the only way to ensure that MPO links meet the application performance requirements. Despite the fact that pre-terminated MPO fiber cables are manufactured and tested by vendors to comply with ANSI/TIA and international standards, there are many factors that can potentially impact performance. First of all, MPO connectors are harder to clean than duplex connectors. The 12-fiber MPO interface features an array with a much larger surface area, which unfortunately makes it easier to move contaminants from one fiber to another within the same array during the cleaning process. 40 and 100 Gbps MPO fiber applications also have much lower loss budgets so it’s important to ensure the highest testing accuracy as possible.
