摘要： A method and apparatus is provided for reducing impairment to an adiabatically chirped optical signal propagating in an optical communication system. The method begins by receiving an adiabatically chirped optical signal that has traversed one or more network components in the optical communication system. The optical signal has a parameter characteristic of signal quality (e.g., an extinction ratio) that is reduced at least in part by a fidelity-degrading transmission slope accumulated in the one or more network components. A fidelity-enhancing transmission slope imparted to at least one wavelength of the adiabatically chirped optical signal at one or more select points along a transmission path of the communication system so that the optical signal experiences an increase in said parameter characteristic of signal quality.

摘要： The specification relates to a repeaterless branch powered fiber optic communications system. The system comprises an optical fiber cable trunk, configured in ring topology, with one or more telecommunications hub, and one or more branching unit serially interconnected therein. Branching units are provided as convenient add/drop points along the trunk ring from which branch fiber optic cable radially extend to cable stations. Cable stations insert and extract telecommunications traffic from the trunk ring over the branch fiber optic cables. In addition, the branch fiber optic cables are also coupled to light emitting power sources. The branch fiber optic cables deliver the energy produced from these power sources to optical amplifiers serially embedded within the branch fiber optic cables, the branching units, or the optical fiber cable trunks. The optical amplifiers convert the energy delivered from the branch fiber optic cables into amplified telecommunications signals. Thus, remote pumping or energy delivery is achieved without the requirement of additional optical fiber cable runs and further, using solely passive repeaterless components.
摘要翻译：该规范涉及无中继器分支供电的光纤通信系统。该系统包括配置有环形拓扑的光缆中继线，其中一个或多个电信集线器以及与其串联连接的一个或多个分支单元。分支单元被提供为沿着分支光纤线径向延伸到有线电视台的中继环的方便的添加点。有线电视台通过分支光纤电缆插入和提取主干环的电信业务。此外，分支光纤电缆也耦合到发光电源。分支光纤电缆将从这些电源产生的能量传送到串联地嵌入在分支光纤电缆，分支单元或光纤电缆干线内的光放大器。光放大器将从分支光纤电缆传送的能量转换成放大的电信信号。因此，在不需要额外的光纤电缆运行的情况下实现远程泵送或能量输送，并且还使用单独的无源中继器组件。

摘要： In accordance with the invention, a Ge-doped optical fiber having reduced Brillouin scattering loss is made by modulating the tension applied to the fiber during draw. The draw tension is modulated between a low range 10-50 g and a high in the range 150-250 g. The result is SBS suppression with no significant change to end-to-end fiber loss or dispersion factors.

摘要： An upgrade method in which Raman amplification is added to an existing transmission system to provide an increase in power budget and permit a substantial increase in transmission capacity either by time division multiplexing (TDM), wavelength division multiplexing (WDM), or a combination thereof. The power budget improvement permits higher transmission capacity by increasing either a single channel data rate and/or the number of wavelength division multiplexed data channels that can be accommodated by existing fiber links.

摘要： In a WDM optical communication system that includes a plurality of nodes interconnected by communication links, a node is provided that includes a first plurality of transponders each generating and/or receiving an information-bearing optical signal at a different channel wavelength from one another. An optical coupling arrangement, which may include one or more reconfigurable optical switches, transfers the channel wavelengths between a link connected to the node and the first plurality of transponders. The arrangement is adaptable to reconfigure its operational state to selectively direct different ones of the channel wavelengths from the link to different ones of the transponders without disturbing the optical path through the node traversed by any other channel wavelengths. A communications and configuration arrangement is provided, which transfers data identifying the respective channel wavelengths at which the transponders operate from the transponders to the optical coupling arrangement. In response to the transferred data, the communications and configuration arrangement reconfigures the operational state of the optical coupling arrangement.

摘要： A Differential Phase Shift Keying (DPSK) optical transmission system provides time division multiplexing, channel routing and channel add/replace functions. The DPSK transmitter comprises a laser to generate an optical carrier signal; a delay encoder to provide a different delay for each of a plurality, M, of input signal channels; and a M channel phase modulator which phase modulates the optical carrier signal with each of the differently delayed M input signal channels to form a Time Division Multiplexed (TDM) phase modulated optical signal. A DPSK receiver demodulates a received TDM phase modulated optical signal. The system may also include apparatus to route, add, and replace TDM channels.

摘要： A variable dispersion optical unit is used to vary the relative dispersion between an input signal and an output signal of the optical unit under control of a control circuit. The control unit uses an optical homodyne detector to beat the input optical signal with the output optical signal to generate a control signal to adjust the relative dispersion a variable dispersive element. The variable dispersive optical element may be selected from a group of dispersive elements including at least a Bragg grating, a Fabry-Perot filter, a Mach-Zehnder filter, and a waveguide routing element. The variable dispersive optical unit can be used as part of a variable wavelength selective optical circuit (e.g., a tunable wavelength filter) where the varying dispersion characteristics is used to control the selection of the wavelength of the tunable wavelength filter, or is used to select the drop/add wavelength(s) of an Add/Drop circuit.
