Higher Speed Transmission - 100G and Beyond

The exponentially increasing demand on network capacity requires higher speed and cost efficient interfaces of 100G and beyond for scalable next generation networks. For the client side, the IEEE802.3ba standard for 40 Gb/s and 100 Gb/s interfaces is expected to be approved soon in June 2010. For the OTN (optical transport network) line side, the OIF proposed a 100G ultra long haul DWDM approach. In this paper, the traffic growth and resulting network requirements are enlightened. Higher speed technologies are discussed and higher speed transmission experiments over field installed DWDM systems of Deutsche Telekom are briefly summarized performed in the 100GET BMBF and Celtic project framework.
