摘要： In some examples, a transmit assembly is described that may include a first optical transmitter, a second optical transmitter, and a polarizing beam combiner. The first optical transmitter may be configured to emit a first optical data signal centered at a first frequency. The second optical transmitter may be configured to emit a second optical data signal centered at a second frequency offset from the first frequency by a nominal offset n. The polarizing beam combiner may be configured to generate a dual carrier optical data signal by polarization interleaving the first optical data signal with the second optical data signal. An output of the polarizing beam combiner may be configured to be communicatively coupled via an optical transmission medium to a polarization-insensitive receive assembly.

摘要： The present invention provides a system, apparatus, and method for efficient optical amplification and transmission of a data-encoded optical signal within a networking device, such as a transmitter or receiver. In various embodiments of the invention, an optical duobinary signal or hybrid duobinary signal is generated and shaped in preparation for amplification of the optical signal by an SOA. The deleterious impact of SOA fast gain dynamics may be reduced by taking advantage of characteristics of a duobinary or hybrid duobinary signal (e.g., a relatively lower pulse amplitude and no phase encoded data) and shaping the optical duobinary pulse (e.g., smoothing amplitude swings within the signal and spectral compression).

摘要： A coherent optical transmitter circuit is disclosed in which controlled chirp is employed, enabling the suppression of nonlinear polarization scattering in dual polarization coherent systems, such as those which employ dual polarization-quadrature phase-shift keying (DP-QPSK). By separately chirping the modulated signals of each polarization tributary signal, the polarization state of the output DP-QPSK signal varies during a time period corresponding to a symbol bit period. Such controlled variations in the output DP-QPSK signal result in the mitigation of nonlinear effects associated with the network infrastructure over which the signal is transmitted, resulting in enhanced system performance. Enhanced system performance, for example, can be seen in greater reach and improved signal quality of the transmitted signal.

摘要： The present invention provides a system, apparatus and method to efficiently switch from one modulation format to another modulation format based upon a current route or path through a network topology of a network communication system. According to various embodiments of the invention, a network topology map is generated identifying one of a plurality of paths upon which a data stream is transmitted from a transmitter to a receiver within a network, the transmitter transmitting the data in a respective one of a plurality of data modulation formats. One or more characteristics related to one of the plurality of optical paths is measured and, based upon such measurement, a desired modulation format is selected. Upon a change in the network topology, the process is repeated such that the modulation format is continuously optimized with respect to the network topology.

摘要： Consistent with the present disclosure, polarized optical signals having the same wavelength are modulated in response to ERZ drive signals, to thereby yield corresponding RZ optical signals. Each of the polarized RZ optical signals includes a plurality of RZ transitions wherein the power of the optical signal returns to zero or a minimal power between bits or symbols. The phase or timing of the ERZ drive signals, however, is controlled, so that the RZ transitions in one polarized optical signal remain interleaved with the RZ transitions of the other polarized optical signal. Alternatively, the RZ transitions of the two polarized optical signals may be controlled so that the two are temporally aligned with one another. Thus, the timing of the RZ transitions of one polarized optical signal relative to the other polarized optical signal may be adjusted to optimize system performance.

摘要： A variety of adaptable electronic duobinary generating filters to be used in communication systems are provided, each filter generating an adaptable electronic duobinay signal which is optimized for system impairments. According to one exemplary implementation, an adaptable electronic duobinary generating filter comprises an adaptable delay-and-add circuit, having an adaptable electronic delay element having a delay αT: 1/T being the bit rate of the binary data input into the adaptable delay-and-add circuit, and α being an adaptation parameter which can be optimized depending on the system impairments. In one optional implementation, the adaptable electronic delay element can be programmably adaptable to optimize against deterministic system impairments. In another optional implementation, the adaptable electronic delay element can be dynamically adaptable to optimize against dynamically varying system impairments. Additionally, in one embodiment, an adaptable electronic duobinary drive circuitry based on the adaptable electronic duobinary generating filter can drive an adaptable optical duobinary transmitter in a fiber-optic communication system to produce an adaptable optical duobinary signal, where the adaptation parameter α is optimized to mitigate certain deleterious fiber-optic transmission system impairments, such as distortions due to narrow optical filtering. Corresponding optical duobinary systems and methods are provided. Similarly, the adaptable electronic duobinary generating filter can be used to form an adaptable electronic duobinary transmitter for an electronic duobinary communication system, to optimize the electronic duobinary signal generated.
