OTN network combines the advantages of optical transmission and electrical processing to provide end-to-end, transparent pipe connections, increased spectral efficiency, and large-capacity transmission capabilities for long-haul transmissions. The primary benefits of the OTN network are presented as follows.
Standard Hierarchy — OTN standards include a standard multiplexing hierarchy, defining exactly how the lower-rate signals ascend into the higher-rate payloads. This allows the WDM platform to shift lower-rate services within 10Gbps, 40Gbps, or 100Gbps wavelengths, without the need for external wavelength demultiplexing and manual interconnects.
Transport Capacity Expansion — OTN networks provide the underlying high-capacity infrastructure for core interoffice, metropolitan interoffice, and broadband business-access networks. Carriers deploy OTN to support the greatest number of services on the least amount of infrastructure.
Reduced Cost — With multiple clients transported on a single wavelength and their specific requirements preserved, the OTN network reduces the overall cost of transport and ensures efficient bandwidth utilization.
Transport Flexibility — Network operators can employ the technologies needed to support current transport demands, while also enabling future adoption of new technologies as business needs dictate. It can easily scale to ring networks, end-to-end networks, and mesh networks.
Timing Transparency — Timing transparency is important for offering wholesale services to third-party providers. The transparency of OTN enables the networks to carry any service, including Ethernet, storage, and digital video, as well as SONET/SDH without interfering with the client timing.
