Photonics tomography for enhancing monitoring capability of optical networks

Ryu Shinzaki,
Motohiko Eto,
Kazuyuki Tajima
et al.

Abstract: We review our correlation based technique for fiber longitudinal power profile estimation which is a key for photonics tomography. Then, we discuss several applications based on this technique, anomaly loss monitoring, polarization dependent loss (PDL) monitoring, fiber-type identification, and nonlinear SNR estimation for optimizing quality of transmission. We show that these applications can detect the position of 3dB anomaly loss or PDL, and differences between deployed and designed fiber types in a multi-s… Show more
