OTN, SDH/SONET, PDH/DSn
The most recent transport solution is OTN which transports TDM circuits over long distances by providing Generic Forward Error Correction (GFEC).OTN is seen as the best transport solution because it offers fault management, performance monitoring, and protection mechanisms, coupled with a low cost-of-entry point and the ability to support current infrastructure with Ethernet, Fibre Channel, SDH/SONET and PDH/DSn networks.
OTN has several advantages:
- A high-reliability network can be configured by using error correction during transmission (Forward Error Correction: FEC).
- Using the OTN switching function supports data transmission to the destination with assured reliability.
- Smooth support is assured for legacy standards like SDH/SONET, PDH/DSn, etc., as well as for as future data mapping standards.
Anritsu test equipment supports OTN FEC function inspections in line with ITU-T standards, while also offering strong support for current SDH/SONET, PDH/DSn inspection standards.
