Alcatel-Lucent and Apollo achieve transmission record for capacity upgrade over 6,500km on transatlantic system A pollo and Alcatel-Lucent Submarine Networks the undersea cables fully flexible WDM grid and multiple modulation schemes tuning the
optical transmission in order to match each channel format to line performance. This spectral engineering capability will be further extended with next- generation technology offered by the 1620 SOFTNODE, enabling an increase in the ultimate capacity per fibre pair of more than 10%. Additionally, with the next step evolution of error correction coding and pulse shaping schemes, more than 10Tbit/s per fibre pair can be unlocked. Richard Elliott, Managing Director of Apollo said, “This new demonstration further proves the technological lead of the Apollo system in offering capacity increases. The achievable capacity of 8Tbit/s per fibre pair has confirmed once again our expectation; that Apollo could carry around four times the
subsidiary of Alcatel-Lucent, have demonstrated a capacity of 8 terabits-per-second of data per fibre pair – equivalent to approximately 1.25 million HDTV channels simultaneously streamed – on the Apollo South system, which connects France to the United States. For the demonstration ASN used its current generation 1620 Light Manager submarine line terminal, equipped with the latest 100 gigabit-per- second technology and made use of innovative detection techniques and advanced error correction coding. In combination with proprietary modulation and pulse shaping schemes, this commercially available solution counteracts the signal distortions and noise that impact high speed, long-distance transmission performance. This capacity demonstration was made possible by implementing smart spectral engineering, which includes a
Field trial carried out on the Apollo South system, connecting France to the US, demonstrated a capacity of 8Tbit/s per fibre pair.

As capacity and connectivity needs continue to increase, the high resiliency to potential degradation at higher speeds combined with the reliability of our technology offer a cost-effective and flexible networking model to cope with content providers and their end-users’ service demands.”

Huawei Marine commences undersea installation of Nigeria-Cameroon cable H uawei Marine Networks has commenced installation of the NCSCS development policy throughout Cameroon’s national territory.” The NCSCS system forms part of Cameroon’s broader strategic than any other optical amplifier. The slim-line titanium casing supports enhanced burial capability through simultaneous
to provide users with faster bandwidth connectivity at a significantly lower cost. By providing direct connection to Nigeria, the cable system will also serve to enhance Cameroon’s position as the major bandwidth hub in the region and internationally to Europe and beyond.” Utilizing Huawei Marine’s industry leading Wavelength Division Multiplex (WDM) and Optical Transport Network technologies, the NCSCS also incorporates the world’s first titanium-cased six-fiber pair repeater. Huawei Marine’s second generation RPT 1660 represents a substantial advancement in innovation as it is not only the smallest repeater but also 40% lighter
(Nigeria-Cameroon Submarine Cable System), Cameroon’s first wholly-owned submarine cable with investment from the Cameroon government. Spanning 1,100km, the NCSCS will link Kribi in Cameroon, with Lagos in Nigeria and deliver 12.8Tbps of capacity to broadband users in both countries by the end of 2015. Jean-Pierre Biyiti Bi Essam, Cameroon’s Minister of Posts and Telecommunications, said the installation demonstrates “the willingness of the Government to implement a true broadband infrastructure

Mike Constable, Chief Executive Officer, Huawei Marine, said, “We are proud to be entering into the marine installation phase of this landmark project that will bring all-important connectivity to Cameroon and the region. This project represents the culmination of years of research and development and a rigorous qualification regime associated with our second-generation repeater which enhances our network solutions to the ultimate benefit of our customers.”
plan for building a National Broadband Network and the implementation is expected to significantly enhance the development of e-government, e-trade, e-education and e-health programs and boost the economic and commercial development of Cameroon. David Nkoto Emane, General Manager, Cameroon Telecommunications, said, “The NCSCS system will provide new opportunities and further the development of our network in both domestic and international markets. The NCSCS system enables us
