…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 Network.  It is a standard for optical transport (G.709)…

…interfaces including serial 40G for SONET, SDH and OTN, as well as 10G-multiplexed interfaces for SONET/SDH/OTN/Ethernet. The FlexSelect 40G Shelf also features full ITU G.709 OTN support, so when combined with Ciena’s unique FlexiPort technology, OTN extensions and hybrid ROADM capabilities, it enables…

…and even 100GbE.  You may have also heard OTN referred to as G.709 or “The Digital Wrapper” (for a great overview of OTN see the video What is OTN?).   OTN provides several key benefits for the optical network.  First, OTN can support a wide variety of networking protocols…

…better position to launch new telecom services more quickly and cost-effectively once we enter the business market.” The CN 4200 leverages ITU G.709 OTN standards-based technology to enable grooming and aggregation of multiple service types on a single wavelength, providing ENERGIE AG with the most…

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…

…and ODU sub-wavelengths into OTN signals. CoreDirector FS supports sub ODU-1 switching to 155 Mb/s granularity called Optical channel Payload Virtual Containers (OPVCs). By efficiently combining multiple services onto a single OC-192/STM-64 or service- transparent G.709 OTU-2 frame, the FSLMs enable…

…such as high-density metro offices, data centers and head-ends. Delivering the same unique combination of on-demand programmable service delivery, G.709 OTN-based service transparency and intelligent service-level management that has made the CN 4200 a market success, the CN 4200 RS offers four times the…

…optimize bandwidth utilization by combining ‘electronic ROADM’ (eROADM)—sub-wavelength grooming capability based on ITU G.709 Optical Transport Network (OTN) technology—with optical ROADM for enhanced network flexibility. This solution offers VTR an architecture with reconfigurability…

…transmission for third party switches or routers across SONET/SDH or Optical Transport Network (OTN) metro or regional backbones. Ciena’s CN 4350 also now includes support for ITU G.709 standards-based OTN “digital wrapper” functionality for encapsulating and efficiently transporting services…

…CN 4200 with seamless management across both platforms. In addition, the compact WDM platform combines full support for ITU G.709, also known as optical transport network (OTN), with an intelligent switch architecture that enables multiple optical services to be groomed onto any wavelength, improving…
