    Most high-speed multiple-access networks on the market, or those currently under design, operate in a limited geographical environment and are devoted either to data-only or voice-only transmission. However, challenges issued by the marketplace require the full integration of voice, data, and video in a real-time environment. This paper proposes a metropolitan area network that covers a campus env... View full abstract»

    A portable fiber optic local area network has been implemented for emergency command center communications. This network operates under a carrier sense multiple-access (CSMA) protocol and employs an architecture based on a unique active star node. The node consists of a transmissive optical star coupler and active electro-optical transceivers. Terminal-to-node or node-to-node links may be as long ... View full abstract»

    Monomode fibers and long-wavelength lasers provide a practically unlimited transmission bandwidth over very long unrepeated distances. These unique properties open up new applications. Besides the conventional long-haul telecommunications carrier applications, new markets will develop in local networks to take advantage of the low maintenance costs, the flexibility, and the high privacy of repeate...

    This paper describes the operation of a new type of fiber optic local area network (LAN) that has most of the advantages of both the contention and token systems. The new system, called PRENET, is basically a contention system; it has no collisions, no message size or cable length limitations, and no stability problems. It can be loaded up to 80-85 percent of its bus capacity and it has bounded de... View full abstract»

    We consider the use of multiple high-capacity fibers for communications networking. Each user transmits, asynchronously, patterns of optical pulses distributed over the fibers and throughout a time frame. Each receiver has a distinct alphabet of patterns, which are detected by optical correlators. Optical correlation by fiber tapped delay lines provides speedy and easy-to-implement decoders. Thus ...

    Collision detection (CD) is easy to implement in baseband coaxial CSMA/CD networks, but is a formidable design challenge in optical fiber implementations. Seven different methods for detecting collisions in fiber optic networks are described and analyzed. Attention is focused on CD accuracy, CD dynamic range, implementation considerations, and reliability issues. View full abstract»

    A family of LAN (Local Area Network) protocols is presented. The LAN consists of a pair of unidirectional fiber optic buses to which stations are connected via passive taps. The protocols provide round-robin bounded delay access to all stations. Contrary to most roundrobin access schemes, the protocols do not require transmission of special packets (tokens); rather, they simply rely on the detecti... View full abstract»

    A number of fiber optic configurations for a new class of demand assignment multiple-access local area networks requiring a physical ordering among stations are proposed. In such networks, the data transmission and linear-ordering functions may be distinguished and be provided by separate data and control subnetworks. The configurations proposed for the data subnetwork are based on the linear, sta... View full abstract»
