EU funded collaboration results in simpler 100 Gigabit Ethernet networks


Nokia Siemens Networks trials HECTO project’s short-haul transceiver

Espoo, Finland - Telecom operators will soon have a simpler option for upgrading optical networks directly to 100 Gigabit Ethernet (GbE) thanks to technology developed with funding from the European Union. Field trials of the HECTO (high-speed electro-optical components for integrated transmitter and receiver in optical communications) project’s technology have demonstrated that 100GbE networks can be deployed that are less complex than before.

In the HECTO project, which was funded by a European Union grant, Nokia Siemens Networks partnered with component vendors, academic institutions and non-profit research institutes from Denmark, Germany, Greece and Sweden.

The key benefit of the HECTO project is a method that cuts the number of transceivers – the components that send and receive pulses of information carrying light – for 100G network links of less than 40 kilometers by 75%. With HECTO, operators can provide short-haul 100GbE using only one transceiver on a single wavelength, rather than four transceivers at four separate wavelengths. This alone can reduce the complexity of 100GbE transmission providing a cost-effective way to upgrade optical networks.

“100GbE is the next big step in the networking world, bringing the additional capacity that will be needed for new bandwidth-hungry applications and the widespread adoption of smart devices,” says Rainer H. Derksen, senior research scientist at Nokia Siemens Networks. “The HECTO approach is ideal for short-haul transmission because it does not require the complex transceivers needed for longer distance network links. At the same time, it meets the increased capacity demands in the metro and access portions of the network. This landmark project fits well with our vision of using innovation to help operators upgrade to 100GbE without major network investments.”

Nokia Siemens Networks led the HECTO project’s activities surrounding the assessment of component specifications and technology. Nokia Siemens Networks drew on its experience in high-speed transmission trials in both systems evaluation lab experiments and field trials. In addition, the company served as the interface between the consortium and standardization bodies.

HECTO project partners to Nokia Siemens Networks were from Sweden (Photonics and Microwave Engineering department of the Royal Institute of Technology (KTH), Acreo AB and Syntune AB), Germany (Fraunhofer Heinrich Hertz Institute, Fraunhofer Institute for Applied Solid State Physics IAF and u2t Photonics AG), Denmark (DTU Fotonik) and Greece (the University of Peloponnese).

Note to Editors
The focus of the HECTO project was the development of photonic components, specifically transmitters and receivers for high-performance high-speed and cost-efficient communication systems. The main objectives were:

* To develop fully packaged transmitters and receivers suitable for optical systems based on serial 100GbE signals requiring about 110 Gbit/s. In particular, the integrated components to be developed are a prototype of a modulator for about 110 Gbit/s with low driving voltage (Traveling Wave Electro-Absorption Modulator (TWEAM) on InP basis), an appropriate electrical driver amplifier and an electrical multiplexer for the transmitter, a monolithically integrated photo receiver (i.e. a photo detector and an amplifier) and a complete monolithically integrated clock-and-data recovery with demultiplexer for the receiver.
* To determine specifications for all interfaces of the photonic components taking into account emerging relevant standards and to determine application areas for the components and their impact on the specifications.
* To test the fully packaged transmitters and receivers in laboratory system test-beds and to perform tests in field trials.
* To exploit the results of the project, including plans for commercial exploitation by the SME component vendors of the consortium.

The project started in November 2006 and concluded at the end of February 2010.
