DWDM(dense wavelength division multiplexing)-PON technology is applied to subscriber network as the same as EPON or G-PON. And its network components consist of OLT, ONU and RN. Legacy DWDM technologies have been applied on the long-haul part of optical network due to its excessive high cost. But many researchers have successfully devised a few methods which can considerably reduce the cost of equipment. Nowadays DWDM-PON equipment’s has arrived to a level having a competitive price in comparison to E-PON or G-PON on condition of giving equal bandwidth. Recently a major domestic ISP has deployed DWDM-PON equipments in one apartment complex area in the purpose of satisfying ever-increasing bandwidth demand. The ISP increased data transmission capacity from 1 G to 16G without any additional fiber deployment. In this paper we introduce roughly three technologies of implementing DWDM-PON’s optic module and related optic devices. And we also describe pre-test of vendor’s DWDM-PON equipment and discuss the result. Lastly we propose some of network configurations which adopt DWDM-PON technology. By adopting DWDM-PON technology ISP can greatly save the cost of deploying broadband subscriber network.
