Proposed legislation in Texas would classify some PoE cabling as electrical work

By on • ( Leave a comment )

Bills making their way through Texas’s Senate and House of Representatives will, if passed as currently written, categorize any cabling circuit capable of supplying more than 50 watts of power to be electrical work requiring a licensed electrician. As a practical matter, that would mean any cabling circuits that can support Type 3 or Type 4 power sourcing equipment (PSE) or powered devices (PDs), as defined in IEEE 802.3bt, would fit that definition. As specified in IEEE 802.3bt, a Type 3 PSE provides a maximum of 60 watts and a Type 3 PD receives a maximum of 51 watts, while a Type 4 PSE provides a maximum of 90 watts and a Type 4 PD receives a maximum of 71.3 watts.

BICSI will hold an online course, Cracking the Code: Interpreting the National Electrical Code (NEC), on June 10, June 17 and June 24, 2019 from 6 PM to 8 PM EST. The 3-part workshop covers how the NEC is structured, what sections are specific to telecommunications systems and equipment, and how to apply those requirements to real-world conditions. The course presenter will be Craig Duntion, RCDD, OSP, NTS, Training Delivery Specialist for BICSI.

What Ever Happened to the Mechanical Splice?

By on • ( Leave a comment )

While mechanical splice connectors have come a long way and are an ideal field termination method for connectorizing fiber, we rarely hear much anymore about mechanical splicing as a means for joining fibers along a link – even though it eliminates the need for expensive fusion splicing equipment. Fusion splicing, where cleaved fibers are aligned and fused by an electric arc, provides the lowest loss and strongest, most reliable joint.

Did we just witness the most high-tech Super Bowl ever? – Nigeria IoT Blog

Super Bowl LIII was the most technologically advanced in history. The Mercedes-Benz Stadium in Atlanta features a dedicated approach to connectivity; 2,000 wireless access points provides the equivalent 280,000+ sq ft of outdoor coverage (roughly five football fields). The stadium also boasts 4,000 miles of fiber optics and 90 miles of audio cables – laid out in a line, this would be enough to go from Atlanta, to the home of the Rams in Los Angeles, and back again! Fans get individual notifications, alerts and updates based on their location, mobile ticketing, and even an API-powered parking chat bot that will help fans find a good spot. In addition, the NFL is using a range of sensors, worn by the players and placed inside the footballs themselves, to measure player speed and overall movement. Over the past 4 seasons these RFID sensors have provided coaches with a wealth of data on the fitness, power and overall performance of each player on the field, data that’s also shared with the media.

Light Brigade opens ‘remote classroom’ for Fiber Optics 1-2-3 course – Cabling Install 

By on • ( Leave a comment )

Light Brigade has launched a remote classroom format of its popular Fiber Optics 1-2-3 course for the fiber-optic professional who does not need the hands-on training provided in their four-day classroom course. FO 123 remote classroom students login four hours a day for four days to gain a comprehensive background in fiber optics. Upon completion of the course, students have the option of enrolling in Light Brigade’s two-day hands-on FO 123 to advance their fiber skills or prepare for the ETA FOI Certification.

How Fast is Fiber Optic Cable Speed? Read The A – Z Guide of Optic Fiber Cable Speed

By on • ( Leave a comment )

Fiber-optic technology enables more data to be moved in a shorter period compared to old net technologies, such as cable and DSL.  For online users, the higher data speed will cause faster fiber-optic cable rate, higher-quality loading, and also a better experience.
Optical fibers come in two flavors: single mode and multimode fiber. These two fiber types support different speeds and bandwidths and use different types of light sources.
 

PON: Another dimension

By on • ( Leave a comment )

As we start building 5G mobile networks, a new chapter of the PON story is being created. This time, the next PON technology is embracing a new paradigm to achieve higher capacity more efficiently. Leveraging the data centre ecosystem – rather than the transport systems that PON technologies have historically used – 25G PON represents the next stage in fibre evolution and a new dimension to the PON story.

Webinar: Designing infrastructure for industrial or manufacturing networks

By on • ( Leave a comment )

Designing the physical infrastructure for a network in an industrial or manufacturing facility requires careful consideration to identify the right cable media to deploy. Many factors play a role in the selection of the optimum products for any given design. Referencing TIA-1005-A “Telecommunications Infrastructure Standard for Industrial Premises,” provides insight into environmental factors and work areas that will drive the selection of these materials, be it a fiber or copper cabling subsystem. This webinar introduces the specifications and requirements defined in this standard, as well as design and installation procedures for industrial networks. The seminar also will offer solutions that will enable a robust industrial network deployment.

The basics of Wavelength Division Multiplexing (WDM)

By on • ( Leave a comment )

Wavelength Division Multiplexing (WDM) is a technology that increases the data-carrying capacity of optical fiber by allowing multiple streams of data to be transported using different wavelengths of light. The primary benefit of WDM technology is that it requires just a single optical fiber which, in most cases, has already been deployed. Therefore, it is a much less expensive option for expanding network capacity compared to installing additional fiber cables.
