chapter
An operator's view on a flexible and future proof network design and operation is described. Scalability and standardised interfaces are key to achieve an efficient and manageable network operation guaranteeing a seamless and cost efficient interoperability of network elements and layers.
chapter
We review the status of Black Link standardization activities, prospects and challenges on possible elastic-optical extensions, and report on the latest experimental achievements on DSP technology compatibility for next generation 1.28 Tb/s PM-16QAM super-channel.

Plasma, excited with microwave energy, has very interesting properties which are in direct correlation with the excitation frequency. This is due to the reachable high electron density, which itself has an influence on the density of further generated particles like ions, radicals, excited atoms and molecules or UV light. Altogether they are responsible for the high chemical reactivity of microwave...

43-Gbit/s PMD-limited performances of CS-RZ and NRZ have been verified in a joint field trail. CS-RZ showed better performance than NRZ. 2/sup nd/-order PMD of 200 ps/sup 2/ was accommodated in principal state of polarization transmission with FEC.
chapter
PMD induced system outage probabilities have been measured in a joint field trial of NTT and DT. For outage evaluation 43-Gbit/s CS-RZ signals of the NTT WDM system were transmitted over selected high-PMD fiber links of DT's fiber network.

Different schemes of dispersion management for cascaded transmission systems composed of standard monomode fibers (SMFs) and dispersion compensating fibers have been studied considering the most essential boundary conditions for practical network design. Alternating ordering of the compensation sections is found to improve considerably the eye opening penalty for high amplifier spacings of 120 km.
