This study shows the benefit of a two stage hierarchy of coding schemes for achieving maximum data rate transmission in optical fiber communications. A first matched filter identifies the codemicrochannel orthogonal code and a second matched filter identifies the data either BPSQd or pulse position modulated with error correction. The novel achievements of this study are 1 the introduction of group theory Young frame and tableaux methods in characterizing code properties for optimum code design with optimum auto and cross correlation properties 2 the development of Lexicographic Greedy code algorithms for perfect codes and orthogonal codes 3 the demonstration of orthogonal codes as extended Reed Solomon codes and their implementation 4 the implementation of Zech logarithmic code constructions 5 the application of optical Fourier methods implementing matched filters in optical hub systems 6 the analysis of code properties in terms of underlying group symmetry structure 7 the confirmation of the utility of shepherding pulse techniques in bit parallel wavelength division multiplexing BPWD for maintaining pulse alignment and 8 bit error analysis all addressed in order to achieve the goal of the maximum in high data rate optical fiber communications commensurate with available device technology.
