Optical transport network switching. Itu t defines an optical transport network otn as a set of optical network elements one connected by optical fiber links able to provide functionality of transport multiplexing switching management supervision and survivability of optical channels carrying client signals. Defined by recommendation g 709 the otn creates a transparent hierarchical network designed for use on both wdm wson and tdm devices. The optical transport hierarchy oth is a new transport technology for the optical transport network otn developed by the itu. Transport sdn at the dawn of the 5g era.
The itu standard g 709 interface for the optical transport network provides an industry wide frame structure and overhead definition for the photonic layer. It is based on the network architecture defined in itu g 872 architecture. Otn facilitates efficient use of dwdm capacity by ensuring consistent fill rates across a network using otn switches at fiber junctions. A bibliometric analysis and visualization of passive optical network research in the last decade.
Optical network solutions from cisco for packet optical transport data center interconnect dci optical transport networks otn and dense wavelength division multiplexing dwdm. With multiple clients transported on a single wavelength otn provides an economical mechanism to fill optical network wavelengths. This allowed for the transport and aggregation of multiple data rates and services including both fibre channel fc and internet protocol traffic over a single wavelength. The promise of the optical transport network otn is designed to address these issues by delivering a transparent framework to efficiently carry diverse traffic types.
Reduction in transport costs. A centralized switched fabric takes this even further as outlined in the blog with the ability to right size the oduflex container to the desired client bandwidth which. Efficient use of optical spectrum. The optical network was built on the ciena cn4200 wdm platform using the itu t g 709 optical transport network otn protocol as the transport mechanism.
Because the optical transport network or otn protocol is designed with multi service capability an otn muxponder supports various clients including sonet sdh and ethernet.
