Coriant Groove G30 powers INEX internet exchange backbone

Coriant announced that INEX, the Internet peering point for Ireland, has deployed the Groove G30 Network Disaggregation Platform in its backbone network, including 100G interconnect services, to optimise its network as internet exchange traffic continues to grow.

Founded in 1996, INEX serves more than 118 members from points of presence in six data centres in the Dublin region and a regional Internet exchange in Cork, which opened last year. INEX currently has more than one terabit of connected capacity and about 300 petabytes of traffic flowed over the exchange in 2016.

Getting the Most from Currently Deployed Optical Fiber Infrastructure

Optical fibers and optical communication systems are the technologies that made possible the internet revolution and the global availability of high-capacity wireless communications (LTE, 4G, etc.). This fundamental global infrastructure is the result of enormous investments realized by telecommunication operators and governments over the last several decades and leverages the great properties of optical fiber as a transmission medium: large bandwidth, low attenuation, low cost, light weight, and immunity to the electromagnetic field.

Squeezing the margins

Optical networking is becoming smarter. Guesstimates and offline calculations are on their way out; to be replaced by real-time computation and machine learning applied to ‘big data’ generated by the network itself, which can be used to optimise performance in ways that weren’t possible before.

Coriant conducts disaggregation field trial with Telefonica Germany

Coriant reports the successful completion of a trial to show disaggregated 100G, 150G, and 200G optical transmission over live fibre-optic links in Telefónica Germany’s existing 10G DWDM network.

Conducted earlier this year, the trial showed how an open transmission systems and disaggregated networking technology – in this case using Coriant’s Groove G30 platform – can be used to increase network capacity more than 10-fold, avoiding the need to invest in new fibre.

Coriant (booth 1715) will discuss how now, more than ever, innovation at the transport layer is critical to transformation as the ongoing explosion of video and the growing dominance of hyperscale cloud traffic intensify the opex and capex challenges faced by network operators around the world. Coriant is excited to be taking part in OFC 2017, where it will showcase the latest innovations in its portfolio and how they are redefining open, multi-layer transport from the network edge to the optical core. Highlights include the new Coriant Groove Open Line System (OLS).

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.

Optical Layer Pluggables: The End of Hard Choices in the Metro?

This white paper looks at a new approach to building the metro optical layer based on miniaturizing optical layer functions (e.g. amplification, monitoring, wavelength selective switching, and optical supervisory channel) into compact pluggables. In addition to exploring pluggable optical layer use cases, this white paper examines the benefits of pluggables and provides comparisons with traditional approaches, including individual modules and system-on-a-blade architectures as well as fixed WDM and ROADM.

Lightning Strikes and 100G Transport

By: 
Dr Maximilian Herrmann and Dr Maxim Kuschnerov

Aerial fiber plays an important role in the global fiber infrastructure. While cheaper to deploy compared to buried fiber, an obvious challenge for aerial fiber is the exposure to harsh environmental conditions, including thunderstorms. While legacy direct detect transmission technology such as 10Gbps is inherently immune to perturbations caused by severe weather, coherent technology with bit rates exceeding 100Gbps presents new challenges. This white paper discusses the physics of fiber perturbations due to lightning strikes, the resulting challenges for coherent transponders, and how new technology solutions deliver superior resilience to adverse conditions.
