Coriant Expands Open Line System with 7300 OLS

Coriant, a supplier of SDN-enabled end-to-end packet optical and DCI solutions, has introduced the new 7300 Open Line System (OLS) solution designed for long haul and data centre interconnect (DCI) applications.

Optimised for deployment with open DCI transponder solutions such as the Coriant Groove G30 Platform, the new 7300 OLS is designed to deliver superior reach performance and stability for long haul open line system applications to address the growing demand for high-capacity connectivity between geographically-dispersed data centre sites.

The new 7300 OLS solution, which is currently in customer trials, leverages the advanced optical layer performance capabilities of the Coriant hiT 7300 Multi-Haul Transport platform while extending support for core data centre equipment practices such as front-to-back airflow and AC power.

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

The 7300 OLS solution additionally features a portfolio of amplifiers designed to deliver optimum capacity and reach performance over fibre with varied optical impairments and optical link control to enable high engineering margins. Coriant optical link control can also serve to mitigate the affects of degrading fibre quality or sub-optimal fibre types, environmental interference and other service-impacting transmission issues.

Coriant noted that the new solution also expands its portfolio of SDN-enabled open line systems that includes the hiT 7300 Multi-Haul Transport platform and Groove G30 platform, including the recently introduced Groove OLS for metro applications.

Coriant will be showcasing the new 7300 OLS solution, together with its portfolio of SDN-enabled smart router and packet optical transport products at Mobile World Congress 2017.

Teleste and Iskratel partner on DOCSIS + GPON

Teleste of Finland, a provider of broadband video and data communication systems and services, announced a proof of concept (PoC) created with Iskratel, a major European provider of infocommunications solutions based in Slovenia.

Building on the PoC, the two companies plan to deliver and market a new solution for the delivery of Internetbased broadband services integrating Iskratel's GPON technology with Teleste DOCSIS-based mini-CMTS, termed the DAH (DOCSIS Access Hub). The new solution will enable operators to utilise existing last mile coax cabling to extend their fibre networks.

The companies noted that, where FTTH is unsuitable or too costly, hybrid solutions incorporating GPON and DOCSIS can offer a viable option for addressing consumer demand for higher speed Internet connectivity with the ability to support a range of services. Teleste added that GPON and DOCSIS offer roadmaps to support the future development of the two technologies together, while the combination also offers a fast and economical way to deliver high-speed broadband, particularly inside buildings.

Through the agreement, operators can deploy the Iskratel SI3000 Lumia as the GPON OLT and Teleste's DAH as the GPON ONU to provide a plug-and-play solution for delivery of triple-play services. Teleste stated that a single DAH can extend the IP network to all apartments in a building utilising the existing coax cabling, with service available immediately once a DOCSIS cable modem has been connected.

The solution is designed to be particularly relevant for locations where installing new cabling is not viable or not possible, for example as is often the case in historical buildings and city centres in Europe.

Iskratel, operating R&D and manufacturing centres and with around 900 staff and a presence in over 30 countries. offers broadband solutions based on its SI3000 and Innbox product families. Solutions for broadband access and aggregation include fibre and xDSL, along with Innbox CPE. The company's service-centric approach is designed to simplify integration and enable a transition to SDN.

Ericsson Demos 1.2Gbps LTE in Greece with COSMOTE

Ericsson, in partnership with COSMOTE, the unified communications brand of Greece's OTE Group, demonstrated download speeds up to 1.2Gbps in an LTE network.

The demonstration, which took place at COSMOTE mobile network in Greece, used Ericsson’s radio solutions. The downlink speeds were achieved by aggregating three carriers with total 60 MHz of spectrum (3x20MHz), with 4x4 MIMO and 256 QAM, delivered to a Cobham Aeroflex TM500 mobile device.

George Pappas, Head of Ericsson in Greece, says: “The latest Ericsson Mobility Report forecasts 4.6 billion LTE subscriptions globally by the end of 2022. Technologies such as 256QAM downlink and carrier aggregation are essential for delivering high-quality LTE experiences to subscribers in Greece and other markets around the world, and our demonstration with Cosmote showcases Ericsson’s technology leadership in these critical areas.”
