5G networks bring many new technologies and challenges to wired and wireless networks. Now multiple standards organizations require 5G mobile networks to deliver traffic-based Quality of Service (QoS), which is key to operators recovering the large costs of 5G upgrades, because data traffic is the most profitable part of their business.
The exhibit floor at OFC 2020 in San Diego is open and attendance is reported as light. More than 180 exhibitors pulled out of the conference. To provide access to the sessions, show organizers have made the technical sessions available via video conferencing.
To help network operators stay ahead of bandwidth needs driven by 5G, AI and hyperscale data centers, Corning has announced a series of smaller, denser additions to its portfolio of long-haul fiber and cable innovations, including the world’s first smaller-form-factor submarine and terrestrial long-haul fibers in a 200-micron diameter.
As data center engineers and ICT professionals brace for the demands of new technologies such as 5G, edge computing, artificial intelligence (AI) and the continuing growth of software-defined networking (SDN) across the enterprise landscape, they need to prepare data center infrastructure and cabling to support these initiatives while ensuring scalability and flexibility.
BICSI has published the 14th edition of The Telecommunications Distribution Methods Manual (TDMM), its flagship manual. The manual is the basis for the RCDD® exam and has become a world resource in global best practices. The 14th edition incorporates significant changes that reflect the newest trends in ICT technologies, ensuring a project is designed based on the latest standards and best practices. The two-volume TDMM contains vital information on these aspects and even more.
OFC 2020 began yesterday, despite California declaring a state of emergency and cancellations among exhibit hall and conference participants. In response to the growing concerns over the spread out of the Coronavirus the OFC Steering Committee and Program and General Chairs are using infrastructure enabled by the OFC community to allow for virtual technical participation by the international community that has been impacted by the Coronavirus. Details on health and safety measures that have been implemented in response to the Coronavirus can be found here.
Static is an invisible hazard to fiber-optic networks. Electrostatic charges draw and hold unwanted dust particles onto fiber network connector endfaces just like a magnet. Although this dust contamination is merely microns in size and only visible when magnified with an inspection scope, it can still cause serious performance problems for a network. Dust in a signal’s path may change or obstruct the light’s index of refraction, or the route of the signal, through the fiber. This causes insertion loss that weakens the signal and slows down the network speed. And if the refraction angle is altered enough, the network signal may be lost altogether.
Singlemode fiber-optic cabling systems, once found almost exclusively in service providers’ long-haul networks or in expansive campuses, are now commonly being used in data center and enterprise networks. How deep has singlemode gotten into these networks, and how much deeper are they likely to go? That’s the topic of this month’s In-Depth discussion.In the data center and the enterprise, long-wavelength transmission supported by singlemode fiber-optic cabling systems serve today’s networking needs and hold promise for tomorrow.

Because of all the new requirements (e.g,. low latency, more bandwidth), new technologies (e.g. eCPRI) and new line rates (i.e. 10G, 25G) that 5G is imposing on the network, new testing practices must follow suit. Where bad splices or bad connections occurred in the past, 4G networks were quick to forgive, but 5G networks definitely won’t. So, unless thorough 5G testing practices are strictly followed, failure rates on new 5G deployments will increase.
