摘要： A low-loss rectangular-passband multiplexer including a three-arm interferometer coherently connected to a waveguide grating router (WGR), resulting in a passband substantially of type N=3, without intrinsic loss. The three-arm interferometer has a free-spectral range (FSR) substantially equal to the channel spacing and is connected to an M-arm interferometer having a much larger FSR. The three-arm interferometer includes three waveguides each exhibiting a linearly increasing path length optically connected to a 1×3 coupler and a 3×3 coupler. The 1×3 coupler may be constructed from a series of Y-branch couplers.

摘要： A polarization-diverse optical amplifier includes a polarization-sensitive optically active medium and a polarization splitter. The polarization splitter is configured to receive input light, to direct a first polarization component of the received input light to a first optical path segment, and to direct a second polarization component of the received input light to a separate second optical path segment. The active medium has first and second optical ports. The first optical port is at an end of the first optical path segment. The second port is at an end of the second optical path segment. The active medium outputs amplified light from one of the ports in response to receiving the input light at the other of the ports. In a preferred embodiment, the active medium has an internal optical axis, and the polarizations of the first and second components are oriented relative to that axis so that amplification is enhanced. The two optical path segments may include polarization-maintaining optical waveguides.

摘要： A system and method for transmitting and receiving control information over a control channel of a wireless communication system where the conveyed information is coded and then transformed by a set of transform function selected from a plurality of sets of transform functions. The control information is transmitted as replicated sub-frames containing replicated code words and such a string of transformed replicated code words is referred to as a control message. At a receive end inverse transform functions from different sets of functions are applied to a sub-frame of a control message so that if the sub-frame is successfully decoded the inverse transform function applied to such frame allows the timing of the control message to be determined.

摘要： A telecommunication system, method, apparatus, and computer readable media that implements an open application program interface (API) system in which open API servers pass and receive API commands to applications through a novel proxy. The proxy assists implementing various management functions, such as assigning open API servers to application and monitoring the overall system, and service contract control, all beneficially in a transparent manner. The proxy enables the telecommunication system to handle geographically diverse applications and open API servers. All API command can, but need not, pass through the proxy.

摘要： In a representative embodiment, a transmitter of a WDM communication system is equipped with a Mach-Zehnder modulator (MZM) configured to produce an optical signal corresponding to a duobinary data stream by modulating a beam of light passing through the MZM. A three-level electrical signal is applied to the MZM to modulate the light. At the second signal level, the modulator substantially blocks light transmission. At the first and third levels, the modulator transmits light corresponding to the duobinary “−1” and “+1” bits, respectively, such that a relative phase shift between the optical bits is different than 180 degrees, i.e., the phase shift value employed in prior-art optical duobinary modulation. Advantageously, by appropriately selecting voltages for the first and third levels, the relative phase shift between the optical bits can be adjusted to reduce detrimental effects of optical bandpass filtering typically present in the WDM communication system, thereby reducing the number of decoding errors at the receiver.

摘要： A method for data path provisioning in a reconfigurable data network is disclosed. A data path between a source IP router and a destination IP router is determined taking into account the IP-subnets of the network interfaces of the IP routers included in the path. In one embodiment, the requirement that two IP routers can send packets via their connected interface if and only if the two interfaces are on the same subnet (i.e., the subnet constraint) is completely honored during the data path determination. In another embodiment, the data path is determined while allowing some number of violations of the subnet constraint. A transform network graph is computed and is used to determine the data path taking into account the IP-subnets.

摘要： A method and apparatus are disclosed for monitoring and signaling a path restoration using pre-computed restoration paths following a detected fault on a primary service path in a communications network. A fault occurring inside the restorable portion of a network in heterogeneous or multiple network environments can be distinguished from faults occurring outside the restorable network in accordance with the ANSI Tandem Connection Maintenance standard, T1.105.05-1994. Path restoration is activated only when a fault causing path failure occurs inside the restorable portion of the network. Each conforming node in the restorable portion of the network has the necessary monitoring, signaling and cross-connect functionality and databases to participate actively in real time restoration. Additional non-conforming network elements can be positioned between the restoration nodes without preventing path restoration. With the signaling architecture of the present invention, when an end-node detects a path failure caused by an in-network fault, it formulates a signaling message for restoring the failed path. The restoration signaling message is thereafter relayed from one node to another in the overhead or payload of signaling paths that occupy the same bandwidth that is subsequently used by the restoration path. Once a signaling message is transmitted to an adjacent node in the overhead or payload of a particular signaling path, the node that transmitted the message makes a cross-connect that replaces the signaling path with a segment of the restoration path whose set-up was requested in the transmitted signaling message.
摘要翻译：公开了一种用于使用在通信网络中的主服务路径上的检测到的故障之后的预先计算的恢复路径来监视和发信号通路恢复的方法和装置。根据ANSI Tandem Connection Maintenance标准T1.105.05-1994，可以将异构或多个网络环境中的网络可恢复部分内发生的故障与可恢复网络外部发生的故障进行区分。仅当在网络的可恢复部分内发生故障导致路径故障时，路径恢复才被激活。网络可恢复部分中的每个符合节点都有必要的监控，信令和交叉连接功能和数据库，以积极参与实时恢复。其他不合格网络元件可以位于恢复节点之间，而不会阻止路径恢复。利用本发明的信令架构，当终端节点检测到由网络内故障引起的路径故障时，它制定用于恢复故障路径的信令消息。然后，恢复信令消息在信令路径的开销或有效载荷中从一个节点转发到另一个节点，这些信令路径占用与恢复路径随后使用的相同的带宽。一旦将信令消息发送到特定信令路径的开销或有效载荷中的相邻节点，则发送消息的节点进行交叉连接，以将信令路径替换为请求其设置的恢复路径的段在发送的信令消息中。

摘要： A method of data communication. The method includes initially receiving one or more channel quality information signals from each wireless unit. The channel quality information may be received in response to the transmission of one or more pilot signals. Once the channel quality information signal(s) from each wireless unit are received, the method then includes selecting one or more transmit powers and one or more transmission rates for each wireless unit. Thereafter, one or more blocks of orthogonal continuous waveforms may be transmitted over a channel to each wireless unit using the selected transmit power and selected transmission rate.
