Research of CMTS Based on Passive Optical Network

Abstract

This paper presents the implementation of CMTS (Cable Modem Termination System) with PON (Passive Optical Network) technology to transfer IP data in HFC (Hybrid Fiber-Coax) network. By describing the theoretical basis and main function of each module, we introduce work principle of this device: converted the format of data transmitting in HFC network so that it can transfer in IP network, then achieved the aggregation of IP data to transport layer device by PON technology. The results show that the SNR is high and the bandwidth achieves expected value, so this design scheme is feasible.
