Optical performance monitoring applications in transparent networks

14th Annual International Conference on Wireless and Optical Communications, 2005. WOCC 2005, 2005
Summary form only given. Optical performance monitoring (OPM) is an enabling technology for highly transparent and reconfigurable networks. Simple OPM functions such as channel monitoring and discovery are requirements in re-configurable systems. Large transparent regions of the network either created by long transmission distances or transparent pass ...

Optical Performance Monitoring in Digital Coherent Receivers

Journal of Lightwave Technology, 2009
In this paper, we present a method for combined fiber parameter estimation from digital filter coefficients of a polarization diverse coherent receiver. All deterministic linear optical channel parameters like residual chromatic dispersion (CD), polarization-mode dispersion (PMD), and polarization-dependent loss (PDL) are continuously monitored by ...

Asynchronous optical performance monitor techniques for DWDM optical networks

Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat. No.02EX551), 2003
The current techniques of optical system performance monitoring are described and characterized. From the available techniques, we focus our attention on the asynchronous Q method, and it is described and evaluated for several working conditions. This technique allows optical performance monitoring without synchronization, thus allowing the performance

Optical performance monitoring in the MCI network [Invited]

Journal of Optical Networking, 2004
Feature Issue on Optical Performance Monitoring (OPM). The next-generation integrated performance monitor (NGIOPM) will prove to be a necessary tool for MCI to monitor and maintain its optical transmission network. The functions and requirements described for NGIOPM are intended for incorporation into various transmission network elements such as add ...

Optical sampling using a PPLN waveguide for optical performance monitoring

SPIE Proceedings, 2007
Many experiments of optical sampling based on the second-order optical nonlinear interactions in periodically poled LiNbO3 (PPLN) quasi-phase-matched (QPM) waveguides have already been demonstrated during the last few years. There are several processes in PPLN that may be used for sampling optical signals, including sum-frequency generation (SFG ...

Deploying optical performance monitoring in TeliaSonera's network

SPIE Proceedings, 2004
This paper reports on the first steps taken by TeliaSonera towards deploying optical performance monitoring (OPM) in the company’s transport network, in order to assure increasingly reliable communications on the physical layer. The big leap, a world-wide deployment of OPM still awaits a breakthrough.

Optical performance monitoring (OPM) in next-generation optical networks

SPIE Proceedings, 2002
DWDM transmission is the enabling technology currently pushing the transmission bandwidths in core networks towards the multi-Tb/s regime with unregenerated transmission distances of several thousand km. Such systems represent the basic platform for transparent DWDM networks enabling both the transport of client signals with different data formats and ...
