SUMMARY We describe a concept and realization of distance-adaptive (DA) resource allocation in spectrum-sliced elastic optical path network (SLICE). We modify the modulation format and cross-connection band-width of individual fixed-bit rate optical paths to optimize performance with respect to transmission distance. The shorter paths are allocated a(More)
SUMMARY This paper presents an elastic optical path network architecture as a novel networking framework to address the looming capacity crunch problem in internet protocol (IP) and optical networks. The basic idea is to introduce elasticity and adaptation into the optical domain to yield spectrally-efficient optical path accommodation, heightened network(More)
We have confirmed that the temperature-coeficient of the average dispersion of a ZDF transmission line is 100 times smaller than that of a conventional DSF. Temperature-independent 80GbiUs OTDM transmission using the 168km ZDF transmission line has been successfully demonstrated. No penalty was observed for the ZDF transmission line over a temperature range(More)
This paper reports, for the first time, a 43-Gbit/s OTN interface prototype that implements more system functions than optical sending/reception, such as framing, scrambling/de-scrambling, client mapping, and supervisory functions, all with high performance. 1. Introduction Spectral efficiency in fiber bandwidth utilization is quite important for satisfying(More)
