An extremely short header transmission and processing time in a gigabit wavelength-division-multiple-access (WDMA) network has been experimentally demonstrated. This was achieved by using parallelly processed subcarrier hopping pilot-tones in combination with an array of detectors and RF switches. The results showed that, without considering the time consumed in an arbitration circuit, the total processing time of the hopping pilot-tone headers was as short as 40 ns which is independent of the number of network nodes and data transmission rate.

Fibre-in-the-loop (FITL) or hybrid fibre coaxial (HFC) networks are the ideal transmission infrastructure for next-generation wireless communication networks, such as digital microcells, personal communication networks (PCNs) and wireless local area networks (LANs). In this paper, the feasibility of two cost-effective optical fibre transmission technologies, super-frequency-modulation (FM) and analogue-to-digital conversion, for wireless access in broadband optical fibres are experimentally demonstrated. Associated circuit and system implementation issues are investigated. Furthermore, by using a statistical model of multiple access in different microcellular environments, we find that both transmission technologies can meet the dynamic range requirements with a significant safe margin.
