A unified and automated fault management platform for heterogeneous optical networks is quite important for telecom operators to monitor and respond to various levels of network events. In this demo, we are demonstrating the details of the design, implementation and evaluation of the proposed HUBBLE platform while targeting to manage the underlying optical network of a telecom operator in real time. The proposed HUBBLE platform consists of three major building blocks i) a data collection layer that is integrated with the telecom operator infrastructure, (ii) data association and analysis layer that is used to measure the severity levels based on predefined alarm severity levels and constraints, and (iii) user interface layer that is on top of management and infrastructure layer which is used to demonstrate the faulty optical lines and is also integrated with fault management systems. Through the dashboard interface of the proposed HUBBLE platform, telecommunication operator's network optimization experts can easily detect the problems related to either fiber or DWDM link and can take appropriate actions.

Timely detection of Dense Wavelength Division Multiplexing (DWDM) link quality and service performance problems of fiber deployment are important and critical for telecommunication operators. In this paper, we propose a new methodology for network fault detection inside optical transmission systems deployed in a real-operator environment and present the working principles of the system. Our new calculation methodology is used for joint fiber and DWDM link quality evaluation inside the proposed High-level Unified BackBone Link Examiner (HUBBLE) platform. At the end of the paper, We also detail some of the benefits, challenges and opportunities of automation in DWDM networks using the proposed HUBBLE platform.
