…history of OTN Some people use -"OTN-" as shorthand for: -- A particular ITU-T specification, G.709, which defines standard interfaces and rates for high-bandwidth optical signals -- A specific feature of G.709, -"digital wrapper,-" which defines signal overhead that extends the performance-monitoring…

…Family The M6S AND M3S multiservice modules for the CN 4200 provide unprecedented transport flexibility for all services up to 2.7 Gb/s. Based on ITU G.709 Optical Transport Network (OTN) technology, the M6S and M3S enable operators to groom services and implement a variety of serviceprotection scenarios…

» Optical Transport Network (OTN) Optical Transport Network (OTN) G.709, commonly called Optical Transport Network (OTN) or digital wrapper, is a next-generation, industry-standard protocol providing an efficient and globally-acceptable way to multiplex services onto optical light paths. The enhanced…

…automated mesh connectivity and 50ms mesh restoration between Ethernet, OTN, SONET and SDH networks The Optical Transport Network (OTN) defined in ITU G.709, allows network operators to converge networks through seamless transport of the numerous types of legacy protocols while providing the flexibility…

…time. The CN 4200 also provides electrical ROADM (eROADM) functionality, a more practical alternative for most sub-wavelength services. Based on ITU G.709 OTN technology, an eROADM carves wavelengths into individual timeslots to allow sub- wavelength service aggregation and grooming similar to SONET/SDH…

…/SDH, 10GbE Local Area Network/Wide Area Network (LAN/WAN) or 10 Gb/s OTU-2 ports on the same module. The FlexSelect 40G Shelf is compliant with ITU G.709 Optical Transport Networks (OTNs), providing transparency for current client services and investment protection as new protocols emerge. The shelf is…

…include routing to a more-centralized service edge, using multiservice pseudowire capabilities to converge legacy services onto Ethernet, and leveraging G.709 Optical Transport Network (OTN) to optimally combine, distribute and manage both IP/Ethernet and high-speed Time Division Multiplexing (TDM) traffic…

…customer demand drives new, higher bandwidth Ethernet services. Additionally, the programmable approach to optical services and the adoption of ITU G.709 (OTN) for network transparency allows operators to offer a standards-based hand-off across platforms and other carriers-' networks. Ciena's offerings…
