Abstract :
This paper discusses the key design issues in applying both CWDM (coarse wavelength division multiplexing) and optical hub technology to an access network. The purpose is to reconsider characteristics of both optical circuits (such as a splitter, a coupler, a laser diode, a photo diode) and CWDM technology, and to try to find improved optical components deployment in access areas. The core of the network is composed of optical components, i.e., optical hub and fibers. CWDM functionality (such as LD and PD) is provided by newly designed ONICs (optical network interface card) located at a station site. The proposed access network structure has advantages in simplicity and scalability. Test bed implementation is included.
