Black Swans and Fiber Networks

A black swan event is defined as “an unpredictable event that is beyond what is normally expected of a situation and has potentially severe consequences.” The phrase originated because people assumed that black swans didn’t exist because nobody had recorded seeing one – until finally someone did. It turned out black swans existed but were extremely rare, and it was hard to predict when or where someone would encounter one. The COVID-19 pandemic in some ways has been a black swan event, and the communications sector has been no exception. One impact on our sector is that data traffic has shot up at an unprecedented rate, a result of schools closing and orders to shelter in place and work from home. This experience is one example of a fundamental truth of network design: patterns of demand in data traffic are hard to predict (other than that they will grow rapidly on average). The solution is to focus on building physical access networks that have the capacity to respond to changing demands, and the accessibility to make use of that capacity where and when it is needed.

Webinar: Fiber Deep Networks for Today’s Enterprise: Part 1

How can you deliver a reliable 4th Utility connected experience so you can face the demands of a modern network? In this webinar, Corning discusses how optical network solutions provide a future-ready platform that can help support in-building applications like Wi-Fi, cellular, cameras, A/V, lighting and more. We will also walk through an Intelligent Building case study that used remote powering, software defined networking, cellular and optical network solutions to provide an easy to manage, scalable, and cost-effective common infrastructure that saved more than 25% over traditional copper networks.

DWDM basics

  DWDM is an optical multiplex technique. It combines multiple discrete transport channels of different wavelengths and transmit them on a single optic fiber. For example, if we multiplex 32 signals of STM-1 level, then optic fiber capacity will be increased from 2.5Gbps to 80 Gbps.This DWDM tutorial covers basics including DWDM transmitters and receivers and describes optical fiber basics, optical amplifier and other system components.

Singlemode vs. Multimode Fiber: The Real Differences

As bandwidth usage intensifies, costs of fiber optic cable continue to decrease and emerging technologies demand faster speeds and more reliable connectivity, fiber cable is becoming a practical solution for many cabling projects. Before you decide for sure that fiber is the right way to go for your project, there’s another decision to make: Do you need singlemode or multimode fiber?

The Top 5 Ways Municipal Fiber Networks Can Help Communities

While many communities across the country are already using fiber optic cables to connect traffic signals and sites, more and more municipal communities are using fiber-optic networks to create connections and advantages for their community and its residents, including helping communities rebound from weather, attract and stimulate new business, attract and retain residents, reduce dependency on communications companies, and prepare communities for the future.

Webinar: Installing, Terminating, and Testing High-Density Fiber-Optic Cable

As fiber-optic cabling continues to grow in popularity, it is being installed in more types of environments than ever before. Some of these environments have inherent restrictions on or challenges to routing, installation, termination, and verification practices. While some recommended practices apply across a broad range of applications and environments, other fiber deployments require unique or specialized practices. This webcast looks at fiber deployment in different environments, including an examination of multiple termination styles, proper test procedures, cleaning processes, and inspection techniques.

Quick Tutorial on Bend Radius

A quick tutorial on bend radius from the Fiber Optic Association: All FO cables have specs that must not be exceeded during install to prevent irreparable damage to the cable: pulling tension, min bend radius, crush loads. Installers must understand these specs & know how to pull cables without damaging them. Why is it important? Not following bend radius guidelines can lead to cable damage. If the cable is damaged in installation, the manufacturer’s warranty is voided. That means if you are pulling a cable over a pulley, that pulley should have a min radius of 260mm/10″ or a diameter of 520mm/20″ – don’t get radius and diameter mixed up!

Fiber for Breakfast

The Fiber Broadband Association is proud to announce its weekly live video series. Fiber for Breakfast is a 30-minute live video discussion hosted by our President and CEO, Lisa R. Youngers, and featuring industry thought leaders on current topics that explore fiber as the critical infrastructure for 21st century communications as well as other connectivity and workplace issues presented during these challenging times. Fiber for Breakfast takes place every Wednesday at 10am ET.

FOTC panelists answer fiber-related questions

When we caught up with four members of the TIA’s Fiber Optic Technology Consortium after their panel discussion at the BICSI Winter Conference, we asked them questions they didn’t have the opportunity to address on-stage. Among the topics: the installed base of singlemode, multimode’s future, keeping MPOs clean, and high-speed connectivity.

Fiber Type Matters When Simulating Optical Links and Latency

Simulating real-world fiber optic links and time delays in the lab environment is both a frequent and necessary task for engineers performing R&D and equipment certification testing processes.  With the evolution to more advanced network architecture, increasing speeds of 400G and beyond, and latency always being a key element, replicating the field network as closely as possible in the lab is critical to ensure systems will perform as expected post-deployment.
