Elastic optical networking is attracting much attention as a promising solution to achieve spectrum-efficient transport of higher data rates at 100 Gbits/s and beyond. If we draw an analogy to virtualization in cloud computing, it can be seen as network level resource virtualization of optical networks where spectrum resources in optical links are segmented… (More)
This paper presents the recent progress of 40-Gbit/s time division multiplexing (TDM) transmission technologies based on 0.1-/spl mu/m InP HEMT ICs and new optical devices operating at 40 Gbit/s and beyond. System experiments demonstrate that the 40-Gbit/s TDM system is very attractive for upgrading transmission capacity into the Tbit/s range.
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)
The transmission performances of zero-dispersion-flattened transmission line, which consists of standard single-mode fiber and reverse dispersion fiber are described. High-capacity wavelength-division multiplexing (WDM) transmission based on 10-Gbit/s signals is demonstrated using the transmission line.
We overview the concept and key elements of elastic optical path networking and the benefits in terms of spectral resource savings, disaster survivability, and efficient IP traffic offloading. We also discuss the growing anticipation for advanced optoelectronic devices to support future elastic optical networks.
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)
