Fiber-to-the-Home Services Based on Wavelength-Division-Multiplexing Passive Optical Network

TLDR

More than 75 Mb/s per subscriber is required for triple‑play services, and WDM‑PON is the most favorable high‑speed access technology, with mature components such as athermal AWG and low‑cost light sources. The authors propose and implement a WDM‑PON system as a platform for triple‑play services. The system employs an ASE‑injected Fabry‑Perot laser diode scheme, offers 32 channels at 125 Mb/s, adopts Ethernet Layer 2, and uses multicast and VLAN to integrate IP‑HD broadcast, VoIP, VOD, and video telephone. The services were demonstrated using the WDM‑PON system.

Abstract

It is anticipated that more than 75 Mb/s per subscriber is required for the convergence service such as triple-play service (TPS). Among several types of high-speed access network technologies, wavelength-division-multiplexing passive optical network (WDM-PON) is the most favorable for the required bandwidth in the near future. Furthermore, WDM technologies, such as athermal arrayed-waveguide grating (AWG) and low-cost light source, have matured enough to be applied in the access network. In this paper, the authors propose and implement a WDM-PON system as a platform for TPS. The system employs an amplified spontaneous emission (ASE)-injected Fabry-Pe/spl acute/rot laser diode scheme. It has 32 channels of 125 Mb/s and adopts Ethernet as Layer 2. Multicast and virtual local area network features are used for the integration of services such as Internet protocol high-definition broadcast, voice-over Internet protocol, video on demand, and video telephone. The services were demonstrated using the WDM-PON system.
