Le Mt-Blanc                         

Th.11/12.Le Mt-Blanc • Symposium on Undersea Systems: Technologies and Applications

Chairs: Ekaterina Golovchenko, TE Subsea Communications LLC, USA, and Jose Chesnoy, Alcatel-Lucent, France
 
Session 1: Transmission Technologies
 
Th.11.Le Mt-Blanc.1
Opening remarks J. Chesnoy & E. Golovchenko
 
Th.11.Le Mt-Blanc.2
OADM TECHNOLOGY FOR MESHED CONNECTION IN ADVANCED SUBMARINE CABLE NETWORK
Takanori Inoue and Ryuji Aida, NEC Submarine Network Division, Japan
This talk introduces and discusses the recent achievements of OADM and undersea branching unit technologies for flexible, reliable and robust connection among many stations in advanced international submarine cable systems.
 
Th.11.Le Mt-Blanc.3
TRANSMISSION TECHNOLOGIES FOR TRANSOCEANIC MULTITERABIT NETWORKS
Olivier Courtois, Alcatel-Lucent, France
Recent technical achievements permit to plan the build of new cables for transoceanic WDM 100Gb/s channels, renewing the perspectives of transoceanic interconnection to the terrestrial data backbone, in particular through coherent detection with massive digital processing, combined with large area fibre with high positive dispersion. The recent breakthroughs of transmission technologies will be reviewed as well as their industrial enablers.
 
Th.11.Le Mt-Blanc.4
USING INNOVATED TECHNOLOGY FOR NEXT GENERATION REPEATER PRODUCT DESIGN
Jas Dhooper, Huawei Marine, China
Repeater engineering and design continues to play an critical part in today’s submarine technology and with the ability to leverage new technology a real opportunity exist to adopt small form factor optical repeater design that enables operational improvements for deployment, integration and greater system reliability. With the demand for greater bandwidth/capacity in submarine systems these factors play a critical role in the customer selection process.
 
Th.11.Le Mt-Blanc.5
THE ROLE OF FEC IN COHERENT TRANSMISSION IN UNDERSEA SYSTEMS
Takashi Mizuochi, Mitsubishi, Japan
Powerful Forward Error Correction (FEC) has become of critical importance as undersea networks increase in speed to 40 and 100 Gb/s. This talk discusses recent progress in soft-decision FEC, which dramatically improves the Q budgets of multi-terabit undersea systems. This is vital for combating the poor fiber nonlinearity tolerance of high-speed Digital Coherent transmission systems.

Th.11.Le Mt-Blanc.6
ULTRA-LOW LOSS OPTICAL FIBER SOLUTIONS FOR COHERENT DETECTION UNDERSEA SYSTEMS
John Downie, Corning, USA
We examine the role of optical fibers for undersea transmission systems, with a focus on requirements for high data rate coherent detection systems. Fiber attenuation and effective area are key parameters affecting system performance.
 
 Th.11.Le Mt-Blanc.7
OPTIMIZING THE TRANSMISSION LINE FOR COHERENT UNDERSEA LINKS
Robert Lingle, OFS, USA
Each advance in amplifier, multiplexing, or modulation technology for undersea systems has required re-optimization of the transmission line. The advent of coherent receivers and polarization multiplexing increases the importance of effective area and span loss.
