摘要： A method of forming a preform or blank for a high bandwidth gradient index optical filament, the preform itself and the resulting optical filament is disclosed. The preform which ultimately forms the optical filament includes a barrier layer between a tubular starting member which comprises the cladding and the core, the index of refraction of the barrier layer being equal to or less than the index of refraction of the tubular starting member; there being no step increase in the index of refraction of the barrier layer at the barrier layer-cladding interface nor of the core at the core-barrier layer interface of the optical filament. The barrier layer is formed from a base glass, a first dopant B.sub.2 O.sub.3, and at least one other dopant which is maintained substantially constant in the barrier layer and then gradually varied during the formation of the core. The quantity of B.sub.2 O.sub.3 is also maintained substantially constant in the barrier layer but then gradually decreased during the formation of the core.

摘要： A system subsidizes telephone calls over a network. The system includes a service provider 120 that establishes a telephone call between a calling party terminal 130 and a called party terminal 140 over the network 110. During the telephone call, the service provider causes at least one advertisement 312 to be displayed at the calling, or called party terminal. At any time during, or after, the telephone call, the service provider generates a bill based on a subsidized billing rate related to the display of the at least one advertisement.

摘要： Apparatus for and method of communicating over a local area network is disclosed. Multiple nodes are connected by an optical fiber in a ring architecture. The cable supports multiple subcarrier multiplexed data communication channels for transmitting and receiving message data between the nodes and a control channel for partitioning nodal access to the individual data channels. Tokens are circulated on the control channel indicating the status of each data channel. A node desiring to send, acquires an open data channel by marking the corresponding control channel token to show that the selected data channel is no longer available, inserts the node destination address into the control channel token, and transmits data on the acquired data channel. A node recognizing its address in the control channel token's destination address field for a particular data channel tunes its receiver to accept data on that channel.

摘要： Optical communication methods and apparatus are disclosed for transmitting two or more optical signals with different optical carrier frequencies on a single optical fiber with high spectral efficiency. Each optical carrier is typically modulated with multiple modulated subcarriers. In one embodiment, an optical phase modulator provides cancellation of second order intermodulation products in each optical signal, thereby permitting the optical carrier frequencies to be spaced by 2f.sub.max, where f.sub.max is the maximum modulation frequency. In another embodiment, a single sideband optical phase modulator provides cancellation of second order intermodulation products and one signal sideband, thereby permitting the optical carrier frequencies to be spaced by f.sub.max. Quadrature optical phase modulators for simultaneous transmission of two independent baseband digital data signals or two independent subcarrier multiplexed signals are disclosed.

摘要： An optical waveguide for use in an optical communication system employing a broad spectral source. Mode coupling is present in the propagation of optical signals in the waveguide, and the parameters of the waveguide are such that pulse dispersion produced by the finite spectral width of the source is minimized by utilizing the mode coupling to substantially cause cancellation of dispersion which is linear with respect to waveguide length and which is caused by the mode independent material dispersion and by the mode dependent waveguide dispersion.
