“…Polarization domain monitoring techniques exploit the alterations in the polarization characteristics of optical signals, caused by various channel degradations, for the effective monitoring of these impairments. These techniques can monitor signal and noise powers (and hence, OSNR), for example, through polarization nulling [52]- [55], as well as PMD of the fiber link, for example, by measuring the degree-of-polarization (DOP) of the received signal [46], [56], [57]. These techniques have the advantage of being transparent to data rates and modulation formats.…”

Optical Performance Monitoring (OPM) is the estimation and acquisition of different physical parameters of transmitted signals and various components of an optical network. OPM functionalities are indispensable in ensuring robust network operation and plays a key role in enabling flexibility and improve overall network efficiency. We review the development of various OPM techniques for direct-detection systems and digital coherent systems and discuss future OPM challenges in flexible and elastic optical networks.

We introduce a novel technique to monitor the optical signal‐to‐noise ratio (OSNR) using a Mach–Zehnder interferometer. The error of the novel method is less than 0.5 dB when the OSNR is between 10 and 40 dB in the best working case. In practice, the dynamic range reduces to 10–30 dB because of the influence of polarization, crosstalk, and signal bit rate. The key advantage of this method is its low cost. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 63–65, 2001.
