While the benefits and Return on Investment (ROI) of smart buildings are well documented for tenants, building owners and operators, similar information for cities are limited at best. In addition, cities measure the benefits and ROI of smart buildings differently, and look beyond financial metrics. Part One of this two part article provides an understanding of the types of things that cities care about, and leads to a new set of metrics for evaluating the ROI of smart buildings.
Wavefront shaping has revolutionized the spatial control of coherent light beams thanks to the use of spatial light modulators (SLM) in disordered systems such as biological tissue, white paint or multimode fibers. Different approaches have been developed to control the propagation of coherent light that has experienced scattering, such as iterative optimization, optical phase conjugation, and the measurement of the optical transmission matrix.
Listed here are statements from providers of products and services to the information and communications technology (ICT) industry, about their business-continuity status amid the COVID-19 pandemic. The list is in alphabetical order. We’ll update it as we become aware of changes or additions.
Expanded beam connectors have a high tolerance for dirt and debris, but EB fiber optic systems are not immune to contamination. They should be cleaned routinely but standard fiber optic cleaning tools simply will not work. The CleanStixx™ EB swab can clean 1.2mm and larger EB connectors. The porous, thermally-sintered, variable-density polymer tip fits over the lens of the EB connector and removes dust, liquids and finger prints delivering a fast, reliable fiber optic network
To handle higher bandwidth, improve network density, and prepare for future upgrades, more data center designers and network managers are moving to multi-fiber push-on connections or MPOs in their fiber network infrastructure. This White Paper provides an overview of all things MPO, including fiber counts, color coding, cleaning, and polarity considerations.
NASA uses simulation software to design spacecraft, predict satellite orbits, and train astronauts. But modeling and simulation are powerful tools that can generate valuable information anywhere they can be applied. In the early 2010s, a group at the Jet Propulsion Laboratory (JPL) successfully used simulation software to model the data transmissions, storage, and processing within and among all the sub-systems on a hypothetical spacecraft. The team wanted to predict the performance of a possible replacement for outdated, inefficient spacecraft data networks.
What is an #OTDR and what does it do? This free poster answers your questions, and serves as a guide to OTDR trace analysis and Smart Link Mapper icon-based fiber link views. Learn everything you need to know about OTDRs.
Walking into a new stadium or venue, it is easy to forget how much planning and infrastructure go into creating a great fan experience. Being able to stream video or post content to social media on your phone, along with 65,000 of your closest friends, requires an incredible amount of planning and execution long before any fan arrives.
Right now, optical technologies comfortably support lane speeds of 50 Gb/s for multimode fiber with 100 Gb/s lanes soon to follow. In their search for bigger, faster pipes, network operators are focusing on two areas: improved optics and the increasing use of multiplexing. Of course, the two are not mutually exclusive. Many of the most attractive technologies involve both multiplexing and improved optics.
Transceivers supporting 400 GbE for #datacenters are nearing significant commercial availability, and #400G #coherenttransmission has reached the field. Join #Infinera’s Geoff Bennett on 3/25 for a @lightwaveonline webinar on the state of 400G+ #technology
