20110274427 | DYNAMIC TRAIL TERMINATION POINT CREATION FOR OPTICAL TRANSPORT NETWORKS - The present disclosure provides dynamic service provisioning by creating embedded Optical Transport Network (OTN) ports on the fly during mesh restoration or circuit provisioning. These dynamically provisioned ports are referred to herein as “fast paths” with all the management objects created in a “slow path” so that they do not interfere with mesh restoration performance. During network failures, these dynamically created objects are deleted via the “slow path” and a new mesh path supports “fast path” creation of these objects. This results in substantial increase in mesh performance and also provides enhancements for operators allowing a “Click and Go” model to provision circuits across a network. This also reduces routing scaling issue as the routing itself is against the OTU level and not against the embedded lines. | 2011-11-10 |
20110274428 | BUS-BASED OPTICAL NETWORK SYSTEM - A bus-based optical network system comprising optical fibers, optical line terminals (OLTs), and a plurality of optical network units (ONUs) is revealed. The OLT consists of the near part (OLTN) and the far part (OLTF). Optical fibers respectively form the transmitting and receiver buses (T Bus and R Bus) with the technique of time-division multiple access (TDMA). The slot flows on both buses are in opposite directions. The OLTN performing traffic control is situated in or near a central office (CO) while the OLTF is far from the CO. ONUs, whose MAC performs traffic control, connect with two buses and share their bandwidth. The MAC with traffic control keeps the performance of the network from degradation. The required numbers of COs and optical fibers for establishing the bus-based network are so smaller that the cost of the network can be significantly reduced. | 2011-11-10 |
20110274429 | METHOD AND APPARATUS FOR PHASE SHIFT KEYED OPTICAL COMMUNICATIONS - A burst-mode differential phase shift keying (DPSK) communications system according to an embodiment of the present invention enables practical, power-efficient, multi-rate communications between an optical transmitter and receiver. An embodiment of the system utilizes a single interferometer in the receiver with a relative path delay that is matched to the DPSK symbol rate of the link. DPSK symbols are transmitted in bursts, and the data rate may be varied by changing the ratio of the burst-on time to the burst-off time. This approach offers a number of advantages over conventional DPSK implementations, including near-optimum photon efficiency over a wide range of data rates, simplified multi-rate transceiver implementation, and relaxed transmit laser line-width requirements at low data rates. | 2011-11-10 |
20110274430 | Optical transmission system - An optical transmission system, where in an optical transmitter a detection bit having a specific pattern set according to the number of bits to be transmitted within one symbol time, is imparted with respect to a transmission signal in which transmission information has been encoded according to a preset format, and an optical signal generated by modulating light according to the transmission signal is transmitted to a transmission line. In an optical receiver, logic inversion or bit swap of received data is detected and compensated by using the detection bit included in the received signal, a decoding process of the compensated received signal is executed. As a result, when an optical signal capable of transmitting multi-bit information within one symbol time is transferred, it is possible to realize excellent transmission characteristics, by reliably compensating an error in received data caused by the modulation format or the multiplex system of the optical signal. | 2011-11-10 |
20110274431 | APPARATUS AND METHOD FOR CONTROLLING A DYNAMIC GAIN EQUALIZER - Consistent with the present disclosure, a method and apparatus for providing a uniform spectral gain of an optical amplifier is provided. Namely, a “balancing” step is carried out in which an optical channel having the lowest power level input to an optical circuit, such as an dynamic gain equalizer (DGE), is assigned a zero “attenuation error” and is substantially un-attenuated by the DGE. The lowest power level optical signal does not require further attenuation and effectively serves as a reference power level, which the power levels of the remaining optical signals are set to. For example, remaining optical signals are assigned either positive or negative attenuation errors relative to the zero attenuation error based on optical signal input powers to the DGE and accumulated DGE attenuations over time. Those optical signals having a negative attenuation error are substantially unattenuated by the DGE, because such optical signals are adequately attenuated and do not require further attenuation. On the other hand, the DGE is controlled to attenuate those optical signals having positive attenuation errors to thereby flatten the output spectrum of the amplifier. In one example, interpolation techniques may be employed to control those portions of the DGE (e.g., attenuators or pixels) that do not receive a channel, such that adjacent pixels that receive channels may impart a desired amount of attenuation. In addition, further interpolation may be provided to appropriately control the DGE pixels, if the number of channels supplied to the DGE is different than the number of pixels of the DGE. | 2011-11-10 |
20110274432 | Amplification of Interleaved Optical Signals - A technique for generating a data signal and a beacon signal for free space optical communications involves generating a data signal having a first optical wavelength and a beacon signal having a second optical wavelength. The data signal is encoded with data via modulation at a first modulation rate. The beacon signal is an inverted version of the data signal and can be further modulated at a second modulation rate that is less than the first modulation rate. The data and beacon signals are optically combined to produce a combined signal in which power attributable to the beacon signal is interleaved with and substantially non-overlapping temporally with power attributable to the data signal. The combined signal is amplified via a fiber amplifier, and the combined signal is supplied to transmitter optics for transmitting the data signal and the beacon signal into free space. | 2011-11-10 |
20110274433 | MODULATION IN AN OPTICAL NETWORK - The invention relates to improvements in or relating to modulation in an Optical Network, and to an apparatus, a method and a communications network for modulation in an Optical Network. An apparatus is arranged to receive a modulated optical signal comprising a carrier wavelength and first data. The apparatus is arranged to substantially erase the first data from the optical signal by performing an inversion operation on the modulated optical signal. The apparatus is arranged to receive second data and to modulate the carrier wavelength with the second data for onward transmission of the second data. The inversion operation comprises applying a signal comprising an inverse of the first data to at least a portion of the modulated optical signal. The signal may further comprise the second data such that the modulation of the carrier wavelength and erasure of the first data is performed in a single operation. | 2011-11-10 |
20110274434 | Technique for Simultaneously Transmitting Wide and Narrow Optical Beacon Signals - A technique for simultaneously transmitting wide and narrow optical beacon signals includes generating a laser beam and splitting the laser beam into a first signal on a first path and a second signal on a second path via a wavelength-dependent beamsplitter. A wide beacon signal having a first beam divergence is generated from the first signal, and a narrow beacon signal having a second, lesser beam divergence is generated from the second signal. The wavelength of the laser beam determines an allocation of the laser energy between the wide and narrow beacon signals based on transmittance/reflectance characteristic of the beamsplitter at that wavelength. The wide and narrow beacon signals are simultaneously transmitted in a overlaid manner into free space to support acquisition and tracking in a free-space optical communication system. The beamsplitter can simultaneously transmit or reflect substantially all of a data signal at a different wavelength. | 2011-11-10 |
20110274435 | MULTICORE FIBER TRANSMISSION SYSTEMS AND METHODS - An optical data link includes first and second pluralities of transmission devices, at least one of which is configured as an array. A multichannel transmission link has a first end connected to the first plurality of transmission devices and a second end connected to the second plurality of transmission devices so as to form a plurality of parallel transmission channels therebetween. The multichannel transmission link includes a multicore fiber with a plurality of individual cores having a configuration matching the array configuration of the at least one plurality of transmission devices. The multicore fiber has an endface connected directly to the at least one plurality of transmission devices, with the individual cores of the multicore fiber aligned with respective devices in the at least one plurality of transmission devices. Further described are access networks and core networks incorporating a transmission link comprising at least one span of a multicore fiber. | 2011-11-10 |
20110274436 | OPTICAL COMMUNICATION SYSTEM - Consistent with the present disclosure a transmitter is provided that transmits data in either a “quasi-DP-BPSK” (“QDP”) mode or in a DP-QPSK mode. In the QDP mode, data bits are transmitted as changes in phase between first and second phase states along a first axis or as changes in phase between third and fourth phase states along a second axis in the IQ plane. Although the transmitter outputs an optical signal that changes in phase between each of the four states, a sequence bit identifies which axis carries the data bit. The sequence bit is one of a series of sequence bits that may be generated by a pseudo-random number generator. The series of sequence bits can be relatively long, e.g., 32 bits, to permit sufficiently random changes in the axis that carries the data. Thus, unlike conventional BPSK, in which data is transmitted between phase states along a single axis, the present disclosure provides an apparatus and related method for randomly selecting one of two axes, for example, for each transmitted bit. In the receiver, it has been observed that the MU-CMA algorithm can process data carried by optical signals in the QDP mode with relatively few errors. Thus, the same equalizer (FIR) filter may be used to process BPSK, as well as QPSK data. | 2011-11-10 |
