Field trials of the Hecto technology project (High-speed electro-optical components for integrated transmitter and receiver in optical communications) have demonstrated that 100Gb Ethernet networks can be implemented more simply.
In the Hecto project, which was funded by a European Union grant, Nokia Siemens Networks partnered with component suppliers, academic institutions, and non-profit research institutes in Denmark, Germany, Greece, and Sweden.
The main benefit of the Hecto project is a method that reduces the number of transceivers—the components that send and receive light pulses carrying information—for 100G network links under 40 kilometers by 75%. With Hecto, operators can deliver short-distance 100Gb Ethernet with a single transceiver at a single wavelength, instead of four transceivers at four different wavelengths. This alone can reduce the complexity of 100Gb Ethernet transmission, providing a cost-effective way to upgrade optical networks.
Nokia Siemens Networks' partners in the Hecto project were from Sweden (Department of Photonics and Microwave Engineering at the Royal Institute of Technology (KTH), Acreo AB and AB Syntune), Germany (Fraunhofer Heinrich Hertz Institute, Fraunhofer Institute for Applied Solid State Physics IAF yu2t Photonics AG), Denmark (DTU Fotonik) and Greece (University of the Peloponnese).
