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.

CommScope, Corning make patent-licensing agreement for fiber-connectivity products

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.

SPE technology is designed to connect multiple devices and/or machines to a network and eliminate the need for “translation,” which previously would occur within the gateways. SPE enables full, real-time communication from the sensor to the cloud in a native language without losing information. The technology not only simplifies machine connectivity and data transmission but, in a broader view, facilitates an open ecosystem, with real-time and high-speed communication in a much more cost-effective way.

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.
