As mentioned in my last post, data center interconnect (DCI) is a growing market for the entire optical value chain – from carriers to optical component suppliers. Standard OTN, DWDM, Carrier Ethernet or legacy SONET/SDH platforms alone cannot address the high-bandwidth, low-power, low-cost and high-density demands of DCI. As a result, many network equipment manufacturers (NEMs) have developed specific solutions to address it. Some of the most common solutions are described below ...

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.

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.

In the first installment in this series, we reported that service provider CapEx spending on Carrier Ethernet equipment seems to be overtaking spending on SONET/SDH in transport applications and that the respondents overwhelmingly (nearly 100 percent agreement) indicated support for Carrier Ethernet in the access portion of the network, while closer to 80 percent support its use in the core...
