Coriant enhances network flexibility with CloudWave Optics

Optical transport vendor Coriant has announced CloudWave Optics, a versatile suite of software-programmable photonic layer technologies that brings a new level of flexibility, efficiency, and scalability to next-generation optical transmission networks.

An enabler of the Coriant Dynamic Optical Cloud, Coriant CloudWave Optics feature best-in-class photonics, software-programmable line-side modulation, tunable spectral allocation, and channel frequency flexibility. Recently showcased in a pan-European Tier 1 carrier field trial, these carrier-grade capabilities significantly enhance service flexibility and network scalability in metro, regional, long haul, ultra long haul, and data centre interconnect (DCI) transport applications.

“Our 400G flexi-rate field trial with Coriant successfully demonstrated the real-world value that programmable modulation can play in advancing the state of optical layer flexibility and adaptability,” said Mattias Fridström, vice president and head of technology, TeliaSonera International Carrier.

Designed for cost-effective integration across Coriant’s portfolio of packet-optical transport platforms, including the Coriant hiT 7300 multi-haul transport platform and the Coriant mTera universal transport platform, among others, CloudWave-powered flexi-rate transmission enables network operators to achieve the highest degree of optical performance at the lowest cost per bit.

Coriant says its flexi-rate optics provide flexible, multi-functional provisioning of service capacity with a single, compact and software-programmable line side interface that can dynamically adapt to a wide range of distances and applications. The performance is based on a combination of flexi-rate and super-channel features with dynamically adjustable modulation formats (e.g., QPSK, 8QAM, 16QAM), flexible bit rate transmission options (100G, 200G, 300G, 400G), and state-of-the-art Raman with up to 25.6Tb/s per fibre in meshed optical networks

CloudWave Optics provides lower total cost of ownership via industry-leading power and space efficiency, increased spectral efficiency of up to 33 per cent, increased fibre capacity of up to 166 per cent, and reduced sparing requirements

“Increased demand for dynamic, cloud-centric services and applications is a driving force behind innovation in optical layer technologies,” said Ken Craft, executive vice, products and technology, Coriant. “Our programmable flexi-rate capabilities are specifically designed to help service providers and data centre operators efficiently and cost-effectively scale their service infrastructure in the face of continued demand for network capacity and highly unpredictable traffic patterns and transport connectivity requirements.”
