Simultaneous 10 Gbps data and clock transmission for smart power grid application utilizing the optical fibre and VCSEL technology

Abstract

The study seeks to design a communication system for a power grid, that will ensure real-time and low-latency communication and automation between the utility and the end users. The performance characterization of the VCSEL in G.655 non-zero dispersion shifted fibre transmitting at 1550 nm is experimentally and theoretically analysed. The experiment reported the various evaluations of BER and eye diagrams using a VCSEL and a DFB laser as light sources. There was the successful achievement of 10 Gbps in 25 and 50 km for VCSEL and DFB respectively. In simultaneous data and clock transmission, 0.4 GHz and 10 Gbps over 25 km was successfully achieved using a VCSEL. The study is significant in the establishment of a pervasive communication system as the backbone of smart power grid design technology.
