Summary :

This paper proposes the technology of wide passband wavelength-division multiplexing (WWDM) for access networks offering multiplexed services. The technology greatly relaxes the wavelength setting accuracy requirements of the WDM light source and the multiplexer/demultiplexer (MUX/DEMUX) compared to dense WDM (DWDM) technology. A WWDM optical converter that offers the Internet protocol (IP) service is implemented and its performance assessed at temperatures ranging from 0C to 45C. In addition, we assess three channel transmission (cable television (CATV) and IP services) in the 1.5 µm region as a multiplexed service example. Using the proposed WWDM, we confirm the feasibility of a service multiplexing system that offers simultaneous CATV and IP services in access networks. This WWDM technology is expected to provide cost effective service multiplexing systems for access networks.
