NEC Delivers 100Gbps Transponder for Optical Transmission in Latin America Through Internexa

Tokyo, Mar 17, 2014 - (JCN Newswire) - NEC Corporation (NEC; TSE: 6701) announced today that it has delivered a 100Gbps transponder to Internexa for optical transmission. This is the first such transponder to be provided to Internexa and has already started commercial operation in Colombia.

Internexa is a leading provider of telecommunications infrastructure and ICT services as well as an affiliate of ISA, a business group composed of 30 affiliates and subsidiaries that promote major infrastructure projects and development throughout 9 countries in Latin America.

The Internexa network is open to all operators and features an area of 28,000 km of terrestrial fiber optics primarily mounted on electrical infrastructure that connects Venezuela, Colombia, Ecuador, Peru, Chile, Argentina and Brazil. Internexa capitalizes on the latest technologies as a leader in Internet access services for operators, data transport and ICT solutions tailored to its customers. Moreover, Internexa helps to create an ecosystem for migrating digital contents for the development of "the real Latin-American internet" reaching approximately 380 million people.

The transponder that NEC delivered for the construction of these network projects incorporates a 100Gbps digital coherent technology (1) developed by NEC and a DP-QPSK modulation system (2) to support high-capacity transmissions of a maximum of 96 waves. Prior to its introduction, a test was conducted by integrating NEC's 100Gbps transponder seamlessly into Internexa's existing optical transmission system located on the optical layer of the current 80 x 10Gbps DWDM System provided by a third party vendor. The transponder earned higher marks than its competitors for its signal characteristics, implementation efficiency, footprint and energy-saving performance.

"In recent years, telecommunications traffic is rapidly increasing in response to the growing use of smartphones, machine to machine, cloud computing, digital cities, CDN's, tablets and the launch of LTE services. As a result, the expansion of optical fiber networks that can accommodate this growing traffic is urgently required in Latin America," said Genaro Garcia, CEO, Internexa. "The 100Gbps transponder provided by NEC to Internexa in Colombia has demonstrated significant competitive advantages, such as rapid implementation, efficiency and excellent performance. This allows us to continue offering customers the best services through our networks."

"NEC is honored to be selected as the supplier of the first 100Gbps transponder for Internexa," said Shunichiro Tejima, Executive Vice President, NEC. "We thank Internexa for their trust and support and we are confident that this upgrade will effectively support the operations of Internexa's more than 28,000 km of fiber."

Going forward, NEC will continue capitalizing on its IT and network assets in order to concentrate on key areas that highlight its strengths in providing network systems and services to telecommunications operators and other customers around the world.

Based on its Mid-term Management Plan 2015, the NEC Group is working towards the safety, security, efficiency and equality of society. NEC aims to develop solutions for a wide range of social issues, as a company that creates value for society through the promotion of its "Solutions for Society," which provide advanced social infrastructure utilizing ICT.


(1) Digital coherent technology is an optical transmission technology providing high-capacity transmission over long distances with a high degree of reliability through the use of optical phases in data transmission. At the time of receiving data, it mixes local light with signal light to decode the signal. It also performs digital signal processing to compensate for signal losses that occur in the process of transmission and to reproduce the original transmission data.

(2) Dual Polarization Quadrature Phase Shift Keying (DP-QPSK) modulation system: This is a modulation method in which four different two-bit signal data are assigned to four modulated optical phases, 0 degrees, 90 degrees, 180 degrees and 270 degrees, for individual orthogonal polarized waves.

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
In recent years, at least 40% of companies using cloud applications have experienced data loss. One of the best prevention against cloud data loss is backing up your cloud data.
