BICSI releases 14th edition of Telecommunications Distribution Methods Manual

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.

Streamlined OFC 2020 Begins

 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.
 

A sticky situation: Removing static improves fiber network performance

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.

Applications for singlemode fiber-optic cabling

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.

5G means new RAN architectures, densification and more fiber

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.

TIA initiates work on new Single Pair Multi-Drop (SPMD) copper cabling, component spec

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.
