The Optical Transport Network (OTN) defined in ITU G.709, also commonly called “digital wrapper” is a next-generation, industry-standard protocol providing an efficient and globally-accepted way to multiplex services onto optical light paths. It allows network operators to converge networks…

…example of this is with OTN.  I may have only heard a reference to OTN one or two times during my entire time at Nortel.  At the OFC/NFOEC event a few weeks ago on the Ciena booth, I heard OTN talked about constantly.  So I finally had to ask someone: What is OTN? OTN stands for Optical Transport…

Cable operators' Hybrid Fiber-Coax (HFC) plants pass within half a mile of some 80 percent of business locations. Therefore, extending the fiber plant to reach mid-sized to large businesses has never been easier or more rewarding. But what is the best way to aggregate, transport and switch the services for these customers?

This white paper assesses the key pain points operators face in the core and provides an overview of the main architectural options available to them. Specifically, we discuss switched SONET/SDH networks (the PMO), integrated optics on core routers (IP over DWDM), and switched OTN networking.

…under the title "The value of OTN".  By April of this year, it had garnered a whopping 31 total views.  With a tweak to the title, some better keyword tagging, and a little promotion on our blog, this video found new life as a good introduction to the topic of OTN, and is now one of the most…

The unrelenting growth of bandwidth demand is causing a number of dilemmas for network operators-including how best to accommodate the need to provision higher-rate circuits, both for enterprise private-line customers and for operators' own infrastructure for higher-layer services. End-to-end OTN service switching is the most economical way to compete for and handle the growth in high-bandwidth optical services. No other solution allows operators to turn up new services faster and more efficiently while removing the cost of uncertainty in future traffic mix.
