Enabling ROF Technologies and Integration Architectures for In-Building Optical–Wireless Access Networks
Photonics Journal, IEEE（2010）
摘要
This work presents our recent progress on advanced radio-over-fiber (ROF) technologies for in-building optical-wireless access networks, including multiservice, full-duplex, and polarization diversity ROF system design, as well as the experimental delivery of uncompressed high-definition television (HDTV) signals. The novel polarization diversity technique is proposed to improve receiving sensitivity and increase the anti-interference capacity of the wireless transmission at the in-building environment. Furthermore, the integration architecture of ROF and Ethernet passive optical network (EPON) is investigated, mainly focusing on polar duplex antenna for non-line-of-sight (NLOS) transmission and home gateway for different network topologies. The hybrid system distributes the multimedia services (e.g., HDTV in EPON) and other wireless data services to the terminal rooms over ROF links and thus expands the superbroadband EPON services to the subscribers for the last meters in both wired and wireless ways.
