The Research of a New Kind of Multi-Stage Wavelength-Division-Multiplexed Passive Optical Network Based on Engineering Materials

Article Preview

Abstract:

The passive optical network (PON) is widely used in different kinds of fields in modern society. Among the PON technologies, Wavelength-division-multiplexed Passive Optical Network (WDM-PON), which has much higher bandwidth, is the important future direction of the optical fiber access. The Single-stage WDM-PON is commonly used from Central Office (CO) to concentrated user groups in a specific area, and the applied field is limited. In this paper, a new network structure and the key technologies of WDM-PON have been studied to increase the access range and number of users, reduce costs and accelerate the realistic applications of WDM-PON technology, which has expensive devices and equipment.
