What and where to use 25G SFP28 Optical Transceivers and Cables?

SFP28 stands for Small Form-Factor Pluggable 28. It is the third generation of the SFP interconnect systems designed for 25G performance per the IEEE 802.3by specification (25GBASE-CR). It has the same common form factor as the SFP+, and supports 25Gbps electrical interfaces per channel, making it a cost-effective way to connect within racks and across adjascent racks. It has the characteristics of low power consumption, small volume and high speed, which is beneficial to increase capacity of data center, improve port density and reduce power consumption.

How To Down-Select Colocation Candidates

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.

Why High-Precision Fiber Optic Testing & Measurement is Important for Revolutionizing Data Transmission & Cloud Storage

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.

Design and installation practices for ultra-high-density fiber-optic cabling systems

The need to connect data center facilities to one another, frequently referred to as data center interconnect (DCI), has been a primary driver for optical-fiber and fiber- optic cable manufacturers to develop products containing thousands of fibers. We refer to cables with 1728 or more fibers as ultra-high-density cables, and this article examines those products.

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.

400G in the data center: options for optical transceivers – DCD

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.

Webinar: Industry Update, Optical Cable and Testing for Data Centers

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.
