Most recent achievements from the project to be presented including 73 Tb/s transmission results for mode-division-multiplexing
MODE-GAP, the European collaborative R&D project which is part of the EU 7th Framework Programme and aims to provide Europe with a lead in the development of the next generation internet infrastructure, is to present three post deadline papers at tomorrow’s ECOC conference in Amsterdam.
They will include a transmission paper, which will reveal next level results for mode division multiplexing (MDM), achieving 73 Tb/s. The other two papers will highlight Wavelength Division Multiplexing (WDM) and data transmission over hollow band-gap fibre at 2µm.
“Post deadline papers that are accepted at ECOC reflect only the latest leading edge results,” said MODE-GAP Project Manager Dr Ian Giles.
“Any organisation would be proud to have a single such paper approved and so presenting three highlights the significant progress the project is achieving and to truly world class levels.”
MODE-GAP and its members have already presented ten technical papers in the main ECOC conference describing progress in all aspects of the project. The areas covered were:
1.45 Tbit/s Low Latency Data Transmission through a 19-Cell Hollow-Core Photonic Band-Gap Fibre
Modal Gain Control in a Multimode Erbium-Doped Fibre Amplifier Incorporating Ring Doping
Nonlinear Pulse Distortion in Few-Mode Fibre
Complementary Analysis of Modal Content and Properties in a 19-cell Hollow-Core Photonic Band-Gap Fibre using Time-of-flight and S2 Techniques
Analysis of Light Scattering from Surface Roughness in Hollow-Core Photonic Band-Gap Fibres
Impact of Mode -Coupling on the Mode-Dependent Loss Tolerance in Few-Mode Fibre Transmission
Complexity Analysis for Higher Order Few-Mode Fibre DSP Equalizers
Method to Visualise and Measure Individual Modes in Few-Mode Fibres
Mode-Division Multiplexed 3x112-Gb/s DP-QPSK Transmission over 80km Few-Mode Fibre with Inline MM-EDFA and Blind DSP
Experimental Investigation of Inter-Modal Cross-Gain Modulation and Transient Effects in a Two-Mode Group Erbium-Doped Fibre Amplifier
MODE-GAP also hosted an SDM workshop in conjunction with the Japanese EXAT project on the eve of ECOC, titled Optical Components and Characterisation Requirements for SDM Networks. Spatial Division Multiplexing (SDM) using Mode Division Multiplexing (MDM) is the approach MODE-GAP is focussing on in order to significantly increase the data capacity of a single fibre. This is achieved by using multiple modes within the same core of Few-Mode Fibres (FMF) as independent channels, each capable of similar capacity to an individual single mode fibre.
Key organisations comprising MODE-GAP include the University of Southampton’s Optoelectronics Research Centre, ESPCI ParisTech, OFS Fitel Denmark APS, Phoenix Photonics, the COBRA Institute at Technische Universiteit Eindhoven, Eblana Photonics Ltd, Nokia Siemens Networks GMBH & Co. KG and the Tyndall National Institute of University College Cork. Half-way through a four year programme, MODE-GAP’s mission is to develop transmission technologies based on specialist long-haul transmission fibres, and associated enabling technologies. These include novel rare-earth doped optical amplifiers, transmitter and receiver components and data processing techniques to increase the capacity of broadband networks.
