Paper Abstract

This paper examines possible use of coherent based fiber optic systems in the telephone network. Coherent technology can increase the bandwidth of fiber based systems beyond the limits of current direct detection methods used for today's fiber optic systems by increasing the sensitivity of the receiver. Coherent technology can be used for one operating wavelength or in combination with Wavelength Division Multiplexing (WDM) devices for many operating wavelengths. "Wavelength management" will be necessary for the telephone companies should WDM devices be used with coherent technology. The most likely application for coherent systems is as transport for broadband ISDN when Gigabits per second (Gbps) bit rates and above are needed. High speed transport may be necessary between the remote electronics and broadband ISDN central office, between high speed fiber based Local Area Networks (LANs), and between central offices of a telephone company. System design should hinge on the standards developed for broadband ISDN. First, background information is given to identify the technology basics and application information, then telephone company operations issues are discussed, and finally conclusions are given.
