    This paper reviews the evolution of undersea cable technology from the telegraph cables of the mid-nineteenth century to the optical undersea cables of today. Future systems will use optical fiber amplifiers which offer significant technical and economic advantages. Consequently, emphasis is placed on problems associated with the accumulation of small, second-order effects in long lengths of optic... View full abstract»

    The potential of erbium-doped fiber amplifiers (EDFA) and wavelength-division multiplexing (WDM) technology for expanding transmission capacity in long-distance telecommunications is examined. Properties of EDFA are nearly ideal for application in lightwave long-haul transmission. Nonlinear effects in the transmission fiber and amplifier spontaneous emission noise limit the performance and therefo... View full abstract»

    In future telecommunication systems, efforts will be made to exhaust the almost unlimited transmission capacity of optical fibers by applying optical frequency-division-multiplexing (OFDM) techniques. The switching elements of such networks must be able to process OFDM signals as well as time-division-multiplexing (TDM) signals. The extent to which optical signal processing can be brought into use... View full abstract»

    The authors discuss how the transition in telecommunication networks taking place with increasing use of fiber in all segments of the networks, together with the increasing demand for broadband services, will lead to new network architectures. The customer access portion of these networks may have a large geographical range and high functionality, and may encompass switching functions. The increas... View full abstract»

    Challenges of next-generation transmission technologies are summarized in the context of creating future terabit-per-second networks. The technologies will be realized through both the separate and combined evolution of inherent lightwave capabilities along with time-, wavelength-, and space-domain optical processing techniques. Optical signal processing techniques in the tens of gigabit per secon... View full abstract»

    Some of the factors stimulating the use of asynchronous transfer mode (ATM) are discussed. The objective of extending the flexibility and features that ATM provides from the switching and interoffice network to the local access network to reach the residential and small-business customers is discussed. How the ATM technique could be applied to fiber-in-the-loop (FITL) systems to meet this objectiv... View full abstract»
