OTN infrastructure

Transparent, flexible and efficient

Traffic demands have changed. Today’s network operators have to deal with a variety of traditional and new transport services as well as traffic patterns that are far less predictable. Meeting these demands and avoiding roadblocks requires a new level of flexibility and scale. Optical transport network (OTN) technology provides a response. With flexible service wrapping, grooming and switching functions, it enables a more efficient use of fiber capacity as well as the flexibility to adapt to changing and unexpected traffic demands.

The bedrock of open programmable networking

With several key advantages over legacy solutions, OTN offers a roadmap for tomorrow’s flexible, scalable packet transport.
Our FSP 3000 OpenFabric™ means fewer valuable wavelengths are consumed, enabling networks to scale for longer.

The freedom of open OTN switching

Now operators can utilize standard interface technology as needed in a pay-as-you-grow approach with low initial costs.

OTN scalability through FSP 3000 OpenFabric™

Moving to coherent-only transmission at 100Gbit/s or above delivers significant benefits. However, the majority of services in the metro are still 10Gbit/s and below. With our FSP 3000 OpenFabric™ technology for OTN grooming and switching, network operators can easily aggregate lower speed services onto high-speed wavelengths without capacity lock-in. That means fewer valuable wavelengths are consumed, enabling networks to scale for a longer period of time without running into wavelength blocking scenarios.

A flexible, scalable OTN layer

Compliant with the ITU-T G.709 standard, our FSP 3000 terminals can interface with any third-party OTN interface.

Precision sync transport with optical timing channels

Besides standard OTN features, our FSP 3000 also supports our advanced optical timing channel (OTC) technology, which enables the transport of highly sensitive timing information over OTN-based infrastructure. Conventional methods for transporting PTP over OTN and WDM networks cause major delay asymmetries. This significantly reduces time accuracy, which can lead to critical issues for new technologies such as LTE Advanced and 5G. Our OTC solution automatically compensates delay asymmetries, delivering the precise synchronization needed for 5G networks.
