摘要： A fiber optic digital communication system and associated transponder architecture interfaces Gigabit Ethernet digital data over an extended range fiber optic link (e.g. upwards of 30 to 100 km), using digital data signal regeneration and optical signal processing components, that pre- and post-compensate for distortion and timing jitter, and thereby ensure accurate regeneration of the data at the far end of the extended distance fiber optic link. Regeneration in both the transmit and receive paths compensates for signal degradation resulting from the very substantial `long haul` fiber distance between transponder sites, and timing jitter customarily present in low cost short haul fiber optic transceiver components. A high speed, low jitter, limiting current driver drives a distributed feedback laser, minimizing jitter generation, and optimizing range extension margin.

摘要： A fiber optic telecommunication system has master site linked to a plurality of subscriber interface sites by a single pair of optical fibers. Downlink messages are transmitted in a continuous TDM format over a first optical fiber from the master site to subscriber interface sites, and in a burst mode TDMA format over a second optical fiber from the subscriber interface sites to the master site. Each subscriber interface site is coupled to the optical fiber link by way of a multiple fan-out fiber coupling pedestal at a common location on the fiber pair. To prevent collisions between successive uplink bursts from the subscriber interface sites, a guard band separates successive uplink messages from one another. The guard band duration accommodates optical fiber transmission distance between the common location on the uplink optical fiber and the subscriber interface site whose differential optical fiber transmission distance from the common location is greatest. A subscriber location has a television decoder associated with the subscriber's television set, through which television channel selection signals are input by the subscriber for transmission from the subscriber interface site to the master site. Power is provided by way of a replaceable battery pack, housed in a subterrestrial bell jar configuration, effectively insulating the battery pack from extreme temperature changes and the intrusion of moisture.

摘要： A method for detecting lightning as an electrical atmospheric disturbance and for providing an indication of the geographic position of that disturbance includes the stationing of at least three receivers at known geographic locations in spaced relationship to each other. Signals are encoded at each of the receivers representative of the time of arrival of an electrical indication of an emission from the lightning strike, in relation to a common timing source. All of the encoded signals are transmitted to a central facility and thereafter processed for deriving the position of the lightning strike irrespective of whether the position of the lightning occurred within or outside the perimeter bounded by the three receivers. The system is synchronized with the U.S. Coast Guard LORAN navigation network, and includes various features which permit a more accurate analysis of lightning position.

摘要： A multichannel data link switching control arrangement for synchronizing the substitution of one data channel for another without causing the insertion or deletion of data bits from the data transmitted over the communication path that is coupled to the channels. The switching control arrangement monitors the relative timing between the data on a channel to be replaced and the data on the replacement channel. Precisely controlled delay circuitry delays the data on one channel relative to the other until the data signals on the two channels are within .+-. a quarter bit of each other, at which time the channel substitution is effected.The arrangement includes a pair of control switch units each of which may be selectively controlled to couple either the active channel or the replacement channel to an output communication link. Each switch control unit contains an input multiplexer and an output switch, the operations of which are controlled by a data timing monitoring apparatus or control unit. The outputs of the two switch control units are coupled to signal combining and splitting circuitry the output of which may be phase compared with the data being coupled through either switch unit. A controllable data delay unit is coupled to one channel at the input to the dual switch control unit configuration and serves to selectively delay one channel with respect to the other as the data signals on both are applied to respective switch control units until the data streams on the two channels are synchronized. At that time, a control signal is applied to the two switch control units to effect a simultaneous switching of the output switches in each unit, whereby channel substitution is effected. The delay action of the delay unit remains in the replacement channel, except that no further incrementing of the delay is carried out.

摘要： A repeatered, multichannel fiber optic communication network includes a plurality of full duplex fiber optic channels and one or more auxiliary channels. In order to supervise and control the operation of the network, for both data transmission and fault/maintenance actions, each terminal station contains a processor-based subsystem capable of network monitoring, first level maintenance action, fault isolation, and remote network control and status reporting. This processor-based subsystem interfaces with each fiber optic channel, with an orderwire communication link, and with external input/output devices and surveillance equipment. Three substantially autonomous processor-based sections which are dedicated to performing specific functions within the overall network operation are employed for carrying out these separate interfacing tasks. Each section of the processor-based subsystem in a terminal station contains its own CPU and associated memory and is programmed to carry out specific functions identified with that section. Each section is interconnected with the other two so that, internally, the subsystem is fully integrated.
