OTN was designed to provide higher throughput (currently 400G) than its predecessor SONET/SDH, which stops at 40 Gbit/s, per channel. ITU-T Recommendation G.709 is commonly called Optical Transport Network (OTN) (also called digital wrapper technology or optical channel wrapper). As of December 2009, OTN has standardized the following line rates.
Open Transport Network (OTN) is a flexible private communication network based on fiber optic technology, manufactured by OTN Systems. It is a networking technology used in vast, private networks with a great diversity of communication requirements, such as subway systems, pipelines, the mining industry, tunnels and the like ( ref ).
ITU-T Recommendation G.709 Interfaces for the Optical Transport Network (OTN) describes a means of communicating data over an optical network. [1] It is a standardized method for transparent transport of services over optical wavelengths in DWDM systems. It is also known as Optical Transport Hierarchy (OTH) standard.
The following is a list and description of architecture and requirements as published by ITU-T G.8080/Y.1304, Architecture for the automatically switched optical network (ASON) G.807/Y.1302, Requirements for automatic switched transport networks (ASTN) Call and Connection Management; G.7713/Y.1704, Distributed call and connection management (DCM)
IP over DWDM (IPoDWDM) is a technology used in telecommunications networks to integrate IP routers and network switches in the OTN (Optical Transport Network). A true IPoDWDM solution is implemented only when the IP Routers and Switches support ITU-T G.709. [1]
Traffic grooming is the process of grouping many small telecommunications flows into larger units, which can be processed as single entities. For example, in a network using both time-division multiplexing (TDM) and wavelength-division multiplexing (WDM), two flows which are destined for a common node can be placed on the same wavelength, allowing them to be dropped by a single optical add ...
These bytes are used for client end-to-end information and shouldn't be touched by the OTN equipment. In contrast to SONET/SDH where the data communication channel (DCC) has a constant data rate, GCC data rate depends on the OTN line rate. For example, GCC0 data rate in the case of OTU1 is ~333 kbit/s, and for OTU2 its data rate is ~1.3 Mbit/s.
Telecommunications engineer working to maintain London's phone service during World War 2, in 1942. Telecommunications engineering is a subfield of electronics engineering which seeks to design and devise systems of communication at a distance. [1] [2] The work ranges from basic circuit design to strategic mass developments.
