Coriant offers open line system for long-haul DCI applications

Coriant has introduced a new open optical line system that has been designed to meet the requirements of long-haul data centre interconnect (DCI) as demand for high-capacity connectivity between geographically-dispersed data centre sites continues to grow.

The Coriant 7300 Open Line System (OLS) complements Coriant’s Groove G30 transponder/muxponder DCI platform, and is compatible with open systems from third-party vendors.

Currently in customer trials, the new 7300 OLS exploits the optical layer performance capabilities of the Coriant hiT 7300 multi-haul transport platform, while also supporting core data centre equipment practices, including front-to-back airflow and AC power.

The 7300 OLS offers a broad portfolio of amplifiers that maximise capacity and reach, even under conditions with strong and inhomogeneous optical impairments, the company claims. It features sophisticated optical link control that delivers high engineering margins. Optical link control ensures robust performance by mitigating the influences of degrading fibre quality or non-ideal fibre types, environmental interference, and other service-impacting transmission challenges.

In addition to a compact and custom-built shelf design that maximises space utilisation and power efficiency, the 7300 OLS enables simplified management and control in third-party managed network environments via support for software defined networking (SDN) integration enabled by the Coriant Transcend SDN controller.

“Flexibility, openness, and stability are increasingly critical in long-haul networks as dynamic and hyperscale traffic flows between data centres drive new design criteria and disaggregated deployment models,” said Stefan Voll, vice president of product management, Coriant. “The new 7300 OLS combines best-in-class optical layer performance with data centre optimised features in an open system design to improve DCI performance in long haul transport and ROADM applications.”

Coriant will showcase the new 7300 OLS at Mobile World Congress 2017 in Barcelona from 27 February to 2 March (Hall 2, Stand 2I30).
