100G – Does One Size Fit All?

Late June every summer, the optical networking community convenes on the French Riviera to ruminate about hot topics in the field of optical networking at the “WDM and Next-Generation Optical Networking” conference. This year was no different, with Andrew Schmitt, Directing Analyst with Infonetics Research opening and chairing the sessions of the first day. In his introductory talk Andrew showed a slide summarizing the state of 100G solutions as follows: In 2011 network operators had the choice between two vendors for commercial deployment of 100G systems. In 2012 the list has grown substantially by a factor of five – a point rendered un-debatable by the long list of sponsoring vendors showcasing their 100G solutions(s) in the adjacent exhibition area.

Clearly, 100G has rapidly matured. The time between early hero experiments and commercial product realization has been remarkably short – certainly much shorter than what occurred with 40G technology. One factor accelerating the 100G development cycle has been early consensus across the industry on how 100G should be tackled. The OIF’s recommendation of DP-QPSK modulation for long haul systems allowed the component industry to focus its efforts into one direction. Read the full post

Two Critical Hurdles to 4G Success

Amid last week’s media huddle over the iPhone 4S and the rollout of iOS 5, a report gently crept past the radar attracting little to no attention. The report detailed the speed at which U.S. carriers are rolling out LTE: A speed so rapid that the U.S. is now the global leader in LTE deployments. The country can now claim 47% of all LTE subscriptions. This figure is further strengthened when you consider that Americans will own 71% of LTE handsets by the end of 2011. Verizon, AT&T and MetroPSC please take a bow.

These are incredible figures and highlight just how serious U.S. carriers are at pushing mobile broadband across the country. Special mention should be made of Verizon here. It’s moving forward at incredible speeds and is fuelled by impressive revenues. Read the full post
