Abstract: Disclosed is a dense channel packing wavelength division multiplexed optical fiber communication system that is parsimonious in its cable length requirements and that does not require the presence of widely tunable lasers at the remote terminals. The system comprises a central station and N remote stations (N frequently greater than about 50) connected to the central station by optical fiber means that comprise a "backbone" and l (1<l<N) fiber "laterals". Associated with each remote station RS.sub.i is a predetermined wavelength .lambda..sub.i, typically in the spectral region 1.25-1.6 .mu.m. The central station comprises means adapted for generating electromagnetic radiation of a multiplicity of distinct wavelengths including all .lambda..sub.i. The radiation from the central station is coupled into the backbone fiber and transmitted to the laterals and the remote stations. Each remote station RS.sub.i comprises means for selecting the radiation of the associated wavelength .lambda..sub.
