The authors have discussed an all-fiber sensor network regarding its properties, topologies, tradeoffs, power budget, and potential applications. The tradeoff shows that the star topology, in particular the single-cable implementation, is the most favored topology with the only disadvantage of requiring more fibers. The daisy-chain topology is not favored in all categories except in number of fibers needed and installation handling (which is also favored by the single-cable implementation of star topology). The hybrid topology, which is a mixture of these two and more favored than the daisy-chain, may still by valuable in certain applications in which number of fibers used must be reduced to be less than required by a star topology. Power budget estimate indicates that a daisy-chain network consumes much more power than a star network. All-fiber sensor networks are required in certain applications in which EMI immunity and/or corrosion resistance are necessary. In general, an all-fiber sensor network is more reliable, compact, and light-weight than its copper-wire counterpart, with the only disadvantage of costing more for the time being. Nevertheless, the cost of an all-fiber sensor network is expected to come down significantly soon, since the market of other fiber and laser-diode based applications such as cable TV networks and CD-ROM are growing rapidly.
