Fast, high capacity fiber transmission gets real for data centers

A cutting edge, “off-line” signal transmission mechanism, experimentally demonstrated just a few years ago, is now on-line as a real-time bidirectional transmission system, the company said.

At OFC 2018, the single-most important annual event in optical communications, being held March 11-15 in San Diego California, a research team from Nokia will report the real-time, bi-directional transmission of 78 interleaved, 400 gigabit per second (Gb/s) channels with a 31.2 terabit per second (Tb/s) fiber capacity.

At twice the 200 Gb/s standard rate found in most applications, the C-band signals were transmitted over a single, 90-kilometer-long single-mode fiber. Such a high transmission capacity and rate would offer a particularly attractive capacity bump to current data center interconnections, where nearby data centers are coupled together to form a single, larger center.

The Optical Fiber Conference and Exposition (OFC) is the largest global conference and exposition for optical communications and networking professionals. For more than 40 years, OFC has drawn attendees from all corners of the globe to meet and greet, teach and learn, make connections and move business forward.
