Abstract

The subproject 100GET-ER will develop innovative and cost-effective solutions on network, system, and component level for newly emerging 100GbE networks. Focus is the metro network segment as area of largest anticipated market growth.On the network level, 100GET-ER will investigate novel 100GbE network architectures, optimised protocols and an integrated control plane for high-bit rate Ethernet services.

On the system level, 100GbE switches architectures and solutions for 100Gb/s interfaces will be developed. Exploring the multi-carrier/multi-level signal constellation space, novel concepts for a cost-efficient and impairment tolerant metro WDM transmission technology will be investigated. Selected approaches will be implemented and tested on laboratory demonstrator/prototype level. Candidate technologies are orthogonal frequency division multiplexing (OFDM), sub-carrier modulation (SCM), and multi-level phase modulation (N-PSK) as well as combinations of these methods. The use of low-cost optics in conjunction with powerful electronic signal processing is key to achieve both the transmission performance and the cost-structure required for a commercial implementation in metro Ethernet products.

On the component level, key building blocks such as high-speed analogue-digital (ADCs) and digital-analogue converters (DACs), which are not available commercially, will be developed.

The subproject partners include Ericsson in Germany and Sweden as well as world-wide renowned universities, research institutes and SME’s in both countries. The complementary expertise and experience of the partners are a solid foundation for the anticipated success of the 100GET-ER subproject and the 100GET project as a whole.

Focus areas

Physical layer technologies for NG Ethernet-based transport networks using low cost 100GbE transponders
Prototypes to identify the most powerful technology options for 100GbE transport

Expected outcome

The prototypes will be analyzed in 100Gb/s transmission system tests in order to enable to identify the most powerful technology options for next generation 100 Gigabit Ethernet products.
