Latin American connectivity infrastructure and ICT solutions provider InterNexa, has teamed up with Coriant to successfully complete an open optical transport field trial featuring disaggregated 100G and 200G transmission over third-party optical infrastructure.
InterNexa operates a ring-based optical backbone infrastructure that supports IP and wholesale transport services throughout South America, with more than 49,000 kilometres of optical fibre interconnecting Colombia, Ecuador, Peru, Chile, Argentina and Brazil.
The live field trial was conducted in Colombia across active transmission links on InterNexa’s backbone network using the Coriant Groove G30 Network Disaggregation Platform with CloudWave Optics coherent transport technology. It showcased InterNexa’s ability to cost-efficiently introduce and scale higher capacity services using open networking concepts while facilitating faster time-to-market.
Testing encompassed multiple alien wavelength use cases, including DCI-optimized 200G 16QAM coherent transmission across a direct link between Bogotá and Medellín at a distance of 364 kilometres and ultra-long haul DWDM 100G QPSK transmission between the same cities using an express route through Cali for a total distance of approximately 1,400 kilometres. The latter ring-based alien wavelength use case was implemented across a third-party, 50 GHz ROADM-based network architecture.
Gabriel Jaime Vivares, connectivity and data centre specialist, InterNexa commented: ‘We were pleased with the performance demonstrated in this open transport field trial and impressed with the Groove G30’s ultra-high density. Customised service offerings remain one of InterNexa’s key differentiators, and the ability to easily and cost-efficiently scale bandwidth in a pay-as-you-grow model is a highly compelling feature.’
The Groove G30 platform is a 1RU modular open transport solution, designed to deliver programmable, high speed, and secure bandwidth optimised for the growing capacity demands of mobile, video, IoT, and cloud applications. Widely deployed in web-scale internet operator, service provider, IXP, and cable MSO networks, the platform can be equipped as a muxponder terminal solution and as an Open Line System (OLS) optical layer solution. Open APIs ensure rapid introduction and easy integration within any network operating environment.
Added Lucas Vanagas, managing director, South America, Coriant concluded: ‘We continue to advance the capabilities of this industry-leading disaggregation platform to ensure our Latin America customers are positioned for success both today and well into the future.’
The disaggregated platform has also recently been used in mainland Europe, with long-standing Spanish neutral internet exchange, ESpanix selecting it as the foundation for a high-speed optical backbone network connecting its major data centre sites across Madrid (see Coriant Groove chosen as foundation for Spanish high-speed optical backbone network).
