  • Demand for high speed data transmission has grown considerably and required bandwidth has increased which can no longer be supported by traditional copper networks due to its limited data transmission capacity. Hence, providing broadband access through fiber optic (FO) cables to overcome this restriction has become essential for internet carriers There are various FO deployment methods with different advantages and disadvantageous. Open-cut trenching method has been the traditional approach for installing FO cables. However, there are several challenges associated with this method which increase the importance of considering an alternative for fiber optic deployment. Micro-trenching is an innovative installation method which minimizes surface scaring and potential negative social and environmental impacts. Considering the fact that this method has been rarely used in cold regions such as Alberta and also due to lack of practical information in this area, long-term performance of cables installed using this technique is not well-known. In this research, various FO installation methods are introduced and discussed. To investigate the long-term functionality and durability of micro-trenching in cold regions, two different technologies were employed and monitored over the course of two winters in a parking lot in Edmonton, Alberta, Canada. Physical integrity and optical performance of cables, were compared and investigated for both methods. In order to analyze the productivity, a Simphony simulation model was developed and validated for field data and finally a modification for productivity improvement was suggested.
