AThe data center industry is witnessing a rapidly increasing need for bandwidth, accelerating the transition to 400G. AFL’s latest White Paper examines Ethernet speeds and transceivers, and provides a guide to choosing the right fiber optic infrastructure.
To identify the most suitable colo candidates, many users begin with a simple web search referencing the desired geographical locations. Then, to shortlist the options, users generally evaluate candidates on 12 attributes, including capacity, reliability, efficiency, telecom, risk avoidance, managed services, financial stability, expertise, and costs. Factors most important to some enterprises, such as low cost or cloud direct-connect circuit availability, may be less important to others who might be focused on scalability or cooling density instead. Users must prioritize features and benefits when down-selecting candidate facilities for further consideration.
This article explains why high-precision fiber optic testing and measurement is important for revolutionizing data transmission and cloud storage. For ultra-fast and reliable data transmission & cloud storage, accurate and reliable fiber optic measurement is the essence of quality control. High precision measuring tools provide for real-time measurement of optical fiber cables, product categorization, process testing, and optimization.
CommScope and Corning have entered into a technical collaboration that includes licenses to each company’s patent portfolios relating to high-density fiber connectivity solutions for data centers and central offices. The new collaboration “creates broader availability of innovative optical connectivity solutions designed to accommodate both density and accessibility for system operators worldwide … The global agreement will enable customers to build data centers faster to keep up with the explosion in data and evolving compute demands.
Every inch is also precious within a data center. IT space is in short supply. Therefore, every data center operator strives to accommodate as much performance as possible in as little space as possible. Every additional height unit (HU) that a top-of-rack switch, for example, takes up is missing from the servers below it, thus reducing the maximum computing power of a rack. High density concepts that make better use of the available space are profitable here.
For cloud-scale data centers, their ability to adapt and survive is tested every year as increasing demands for bandwidth, capacity and lower latency fuel migration to faster network speeds. During the past several years, we’ve seen link speeds throughout the data center increase from 25G/100G to 100G/400G. Every leap to a higher speed is followed by a brief plateau before data center managers need to prepare for the next jump.
Currently, data centers are looking to make the jump to 400G. A key consideration is which optical technology is best. Here, we break down some of the considerations and options.
A new wave of high-speed coherent optical components are expected gain widespread adoption in 2021, according to Dell’Oro analyst Jimmy Yu.
While vendors like Nokia, Ciena, and Infinera have been teasing faster and faster optics for years, Yu noted in a blog post that the optical transport market is a research and development heavy industry, with multi-year product cycles. “Grand ideas and proof of concepts announced years ago steadily build toward commercialization and main stream adoption over the course of a few years,” he wrote.
Yu said several long-hyped optical technologies, including those offering higher line rates up to 800 Gb/s, are likely reach the market in 2021.
Computers, electronic devices and digital infrastructures are consuming ever-increasing amounts of electricity. This is confirmed by Milena Gabanelli who, during her DataRoom on Corriere della Sera, reports interesting data on the harmful emissions produced by the technology and their use. In 2008, for example, digital technologies used in the transmission, reception and processing of data and information (ICT) contributed 2% to global CO2e emissions; in 2020 they reached 3.7% and will reach 8.5% in 2025, the equivalent of the emissions of all light vehicles in circulation.
A multitenant data center (MTDC), also known as a colocation data center, is a facility where organizations can rent space to host their data. MTDCs provide the space and networking equipment to connect an organization to service providers at a minimal cost. Businesses can rent to meet varying needs—from a server rack to a complete purpose-built module. The scalability of usage provides the business benefits of a data center without the high price.
The demands being placed on our data centers are larger than ever. This is true for all types and sizes of data centers, from the largest Hyperscale, to Private, and even Edge. This webinar will address advancements in Single and Multimode fiber and how they are being used in data centers. This presentation will look at the latest applications and the requirements for fiber to support them. After that, we will look at testing these fibers, calculating a loss budget for current and future applications, and how you can increase confidence in the test results. At the end of this presentation, you will understand how improvements in fiber construction allow communications at multiple wavelengths are helping to reach speeds in excess of 400G as well as what testing will assure that the fiber has been properly installed.
