Furukawa Electric Co has conducted an experiment in its Mie, Japan facility to demonstrate the installation of a 6912-fiber optical cable with an outer diameter of 1.14 inches (29 mm) in a 696 foot (200m) long conduit with three 90 degree curves and an inner diameter of 32mm. The conduit used was a standard product installed in conventional data center campuses. Engineers confirmed a maximum pulling tension of 84 pounds (372N), well below the maximum pulling tension of 600 pounds (2700N) specified for the cable.
Traditional networks may seem adequate, but the exponential growth of data transfer is putting traditional campus networks to the test. In short, copper wiring limits speed and distance – and both are critical for an effective campus network. Copper only offers transmission speeds up to 1Gbps and reach of 100 meters; it will suffer signal losses and tremendous data slowdowns if they go beyond. Additional investment such as signal boosters or recabling are needed to maintain network performance if the site is particularly large.
Capitalizing on growth in 5G technology and with support from state and local officials, a startup company called viaPhoton has opened a fiber-optics factory in Aurora, where it is hiring 30 people and hopes to add another 200 employees in three to five years.
CEO Baber Abbas said the company will supply data centers and mobile communications companies throughout the Midwest. Its presence here will help Illinois expand access to 5G services statewide.
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.
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 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.
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?
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.
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.
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!
