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.
Churches require a reliable, high-performance and scalable LANs that can withstand the test of time and deliver virtually unlimited bandwidth as applications and services evolve. That’s why church integrators need to stay up with the latest technology, such as the passive optical network (PON) and passive optical LAN (POL).
TIA’s TR-42.7 Engineering Committee on Telecommunications Copper Cabling Systems (568) has issued a call for interest for document ANSI/TIA-568.6, initially titled, “Single Pair Multi-Drop (SPMD) cabling and component specifications.” The standard will address the need to support applications that use a bus topology with multiple branches connecting communication devices.
5G has arrived – but 4G is still king: 4G was the world’s dominant mobile technology last year, supporting more than half (52 per cent) of global connections. Despite the emergence of 5G, 4G will continue to grow over the coming years, increasing to account for 56 per cent of connections by 2025.
