The trade-off between more user bandwidth and quality of service requirements introduces
unprecedented challenges to the next generation smart optical networks. In this regard, the …

Optical performance monitoring (OPM) is the estimation and acquisition of different physical
parameters of transmitted signals and various components of an optical network. OPM …

Publisher Summary This chapter explores optical performance monitoring (OPM) and its
potential for enabling higher stability, reconfigurability, and flexibility in a self-managed …

Today's optical networks function are in a fairly static fashion and are built to operate within
well-defined specifications. This scenario is quite challenging for next generation high …

We experimentally demonstrate a multi-task deep neutral network (MT-DNN) enabled
optical performance monitoring (OPM) for PDM-QPSK/8QAM/16QAM signals, by using the …

The polarization-nulling technique utilizes the different properties of optical signal and
amplified spontaneous emission (ASE) noise for accurate monitoring of the optical-signal-to …

Optical signal-to-noise ratio (OSNR) monitoring is essential to both the operation of reliable
and reconfigurable network and the supply of high quality-of-service. Recently, deep …

OSNR monitoring is indispensable for coherent systems to ensure robust, reliable network
operation and potentially enable impairment-aware routing for future dynamic optical …

Optical performance monitoring (OPM) is an important approach to determine the quality of
optical channels within an optical core network without passing data through optoelectronic …

We describe a simple method to measure the optical signal-to-noise ratio (OSNR) of on-off-
keying (OOK) and differential phase-shift-keying (DPSK) signals by using an optical delay …
