Nokia launches optical portfolio for 400G ecosystems

Technologies and Products

Nokia has launched its WaveFabric Elements portfolio of photonic chips, devices and subsystems, including its fifth-generation coherent digital signal processor family, the Photonic Service Engine V (PSE-V).

WaveFabric Elements portfolio combines digital signal processing (DSP) and optics technologies focused on emerging end-to-end 400G applications, allowing the company to optimise the entire electro-optic engine that powers today’s networks and the transformational upgrades to come. This high degree of vertical integration ensures that Nokia’s optical solutions will meet the unique economic and technical requirements of data centre, metro, long haul, and subsea networks.

The new DSPs are complemented by the CSTAR portfolio of coherent optical engines brought to Nokia via its recent acquisition of Elenion Technologies, a pioneer in silicon photonics. A new family of pluggable transceiver modules allows Nokia to address their critical and expanding role in data centre, IP and optical networks, as well as emerging markets and applications highly dependent upon low-cost optical connectivity, such as access and mobile networking. The CSTAR family of optical engines is currently shipping to customers. PSE-V-based platforms and pluggables will be available beginning in Q4 2020.

Nokia says the PSE-Vs, which can run up to 90 Gbaud, employs the second generation of the industry’s only field-proven implementation of Nokia Bell Labs-pioneered probabilistic constellation shaping (PCS). Combining refined algorithms with the enhanced capabilities of a new generation of silicon, it is capable of transporting up to 800G, while providing 60% greater reach, 40% lower power per bit, and 15% greater spectral efficiency than previous DSP generations. The PSE-Vc enables programmable capacity from 100G to 400G with metro to long haul capability. Its extremely low power enables integration into a variety of pluggable transceiver modules. The CSTAR family of optical engines leverages state-of-the-art silicon photonics and packaging technology, and addresses applications, including intra-data centre, metro DCI and long-reach optical transport. Paired with PSE-V DSPs within Nokia platforms, they are also available independently to industry partners for integration into pluggable transceiver modules available to the broader market. Nokia’s 400G pluggable coherent transceiver modules are optimised to address a range of platforms and applications, including Nokia’s broad portfolio of optical transport, IP, fixed access and mobile solutions. The portfolio includes 400G ZR/ZR+ capabilities in the QSFP-DD form-factor and a higher performance, more feature rich 400G multi-haul variant in a CFP2-DCO form-factor.

Sam Bucci, head of Optical Networks at Nokia, said, “Networks are truly at an inflection point, and 400G will be a catalyst for a significant transformation. With our WaveFabric Elements portfolio, Nokia is committed to supplying the 400G optical ecosystem with components, subsystems and design services, as well as continuing to build the highest performing optical transport solutions for the 400G era and beyond.”

Scott Wilkinson, Lead Analyst at Cignal AI, said, “Nokia is one of a select few companies with the experience of building five generations of DSPs. The company’s expertise in vertical integration is a key competitive advantage in the battle for next generation coherent solutions. The focus on 400G transport in the PSE-V is well-positioned for market needs.”
