The Fujitsu XG series provides cost effective high-speed integration and conversion of Ethernet signals for Synchronous Optical Network (SONET) and other protocols. The XG series' interface flexibility and switching function offers a cost-effective means of running jitter-free SONET services over long fiber optic links, and is ideal for telecommunications service deployments.

Consented in June 2007, the ITU-T G.8262 recommendation (former G.paclock) outlines the minimum performance requirements for timing devices used to synchronize networking equipment that uses Synchronous Ethernet. The recommendation defines PLL performance characteristics, including wander, jitter, phase transients, clock bandwidth, frequency accuracy and holdover.
