Large numbers of passive fibre components (PFC) are required in multinoded networks, built in multimode graded-index fibre. A new technique, called Fused-Head-End (FHE), for manufacturing N-to-M splitters and couplers has been described. The physical properties are studied in terms of modes and mode conversion. If coherent sources are used, modal noise is unavoidable. The mechanism of the PFC in generating modal noise is quantified. The FHE splitter/coupler directly pigtailed to a LED, allows hierarchically structured ring networks and switches to be made which are self-routing. The FHE technique can also be applied to make single-mode PFCs. The first experimental results of a device to be used as a (de)multiplexer and splitter/coupler are reported.
