Application note from Belden breaks down fiber infrastructure for data centers

June 19, 2017
A new technical application note available from Belden is entitled, "Get Ready: New Fiber Infrastructure for Data Centers."

A new technical application note available from Belden is entitled, Get Ready: New Fiber Infrastructure for Data Centers. Authored by Belden's Technology and Applications Manager for Optical Fiber Systems, Qing Xu, the application note's abstract is as follows:

"As speeds increase, optical fiber cabling systems need to be upgraded to support larger data center footprints and growing data traffic bandwidth. In regard to optical fiber cabling standards, specifications have also been updated with improved link performance. Before new optical fiber infrastructure is deployed in data centers, there are a few essential checkpoints to keep in mind:

1. Determine the active equipment input/output (I/O) interface based on application types; 2. Choose optical link media based on reach and speed; 3. Verify optical fiber standards developed by standards bodies; 4. Validate link budget based on link distance and number of connection points.

In this document, we describe current technology trends and the latest industry standards for data center applications, providing referral guidelines for these four checkpoints."
