Performance monitoring in high speed optical networks

SPIE Proceedings, 2009
The world wide growing bandwidth demand in optical networks leads to channel data rates of 40 Gbit/s and higher (e.g. 100 Gbit/s). At these data rates polarization mode dispersion (PMD) is one of the limiting factors even in metro networks. Due to stochastically changing environmental conditions, such as temperature drifts, vibrations and pressure ...

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 ...

Performance Monitoring Method for All-Optical Networks

2009 International Conference on Networking and Digital Society, 2009
All-Optical Networks provide ultra-fast data rates, but present a new set of challenges for network security. However optical performance monitoring (OPM) and optical network management (ONM) are essential in building a reliable, high-capacity, and service-differentiation enabled all-optical network. One of the serious problems with transparency is the

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 ...

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 short reach optical communication systems

With the development of advanced optical communication systems and networks, the critical role of optical performance monitoring (OPM) in system and network operation has emerged. OPM can help service operators to provide users with guaranteed signal transmission, and it can be conducted from both optical domain and electrical domain.
