EPON Based Communication Service Framework under Coal Mine

To solve cascade arising problem of traditional networks under coal mine, this paper has proposed an EPON based Communication Service Framework (E-CSF) under Coal Mine. First, the structure, principles and characteristics of EPON network are analyzed, which focuses on the application of EPON network for the construction of safety information network under coal mine. EPON optical network can completely avoid the passive nature of the external device electromagnetic interference, reduce the circuit and the external device failure rate, improve system reliability. Secondly, EPON can make the ground LAN and monitor network under coal mine connected seamlessly, which will greatly enhance the efficiency, convenience for management and reduces the cost of monitoring communication system. So it is a good solution to communication distance, speed, cost and security problem under coal mine.
