NOTAS: | "Optical transmission systems for trunk lines are used worldwide and systems using optical fibers will be used in subscriber loops in the future. Although the basic technologies are common to both trunk and subscriber systems, optical transmission for subscriber loops must be designed by considering its characteristics and peculiarities. The author discusses optical transmission technologies using single-mode optical fibers for subscriber loops. Part one discusses basic technology and part two gives optical subscriber system examples and optical devices used in the systems. Written for system designers, technical managers, students and manufacturers." |
