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.
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 has expanded its Transcend Software Suite with the introduction of the Transcend Hierarchical Controller, which is designed for enhanced orchestration of multi-layer, multi-domain, and multi-vendor transport networks.
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 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.
This white paper explores strategies to address the challenge of providing the highest level of network availability at the optimal cost for each service.
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.
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.
Optical transport vendor Coriant is the latest company to offer a product aimed at data centre interconnect (DCI) networks with the Coriant Groove G30 DCI platform.
Offering 3.2Tb/s of capacity in a compact and stackable one rack-unit (1RU) box, the new product provides up to six times higher system density and 70 per cent lower power consumption than comparable products, the company claims.
These capabilities drive down operational costs while increasing capacity to help network operators deliver profitable DCI services and enhance the end user cloud experience.
