摘要： In general, the 1G-EPON standard specifies its upstream waveband broadly to allow for low cost lasers to be used to transmit upstream. Often, however, the lasers actually used by many 1G-ONUs to transmit upstream only occupy a narrow waveband that does not overlap with the upstream waveband specified by the 10G-EPON standard. The present disclosure is directed to systems and methods that exploit this fact to efficiently provide for the coexistence of 10G-EPON and 1G-EPON over the same set of optical fibers in the upstream direction.
摘要翻译：一般来说，1G-EPON标准规定了其上游波段，以允许低成本激光器用于向上游传输。然而，通常，许多1G-ONU实际上用于上行传输的激光器仅占用与10G-EPON标准规定的上行波段不重叠的窄波段。本公开涉及利用该事实有效地提供10G-EPON和1G-EPON在上游方向上在同一组光纤上共存的系统和方法。

摘要： Scalability and energy efficiency are key issues in data centers imposing tight constraints on the networking infrastructure connecting the servers. Optical interconnection mitigates electronic limitations but the additional flexibility offered by WDM and datarate across a data center interconnection network requires architectural design, photonic technologies, and operating strategies be selected and optimized to meet power consumption requirements. Multi-plane architectures based upon space-wavelength domain architectures have been proposed to overcome scalability limitations. It would be beneficial to extend space and time switching domains with the wavelength domain for additional capacity to increase throughput as well as providing same electro-optic interface. Accordingly, the inventors have established space-time domain interconnection network architectures with wavelength domain overlay overcoming power consumption issues, especially at low utilization, by exploiting all-optical implementations with active elements which act simultaneously as a switch and an amplifier, and the possibility to remain in an idle state when unused.

摘要： An optical communications subsystem is proposed to permit the multiplexing of multiple, parallel electronic data streams onto a serial, very high speed optical data channel. The subsystem may also be used to generate programmable ultrafast optical data words for the testing of optical components, and system performance testing of very high speed data transmission systems. The key device component, based on a modified arrayed waveguide grating structure, is directly integratable with a high-speed optoelectronic modulator array in a simple, cost effect, and manufacturable configuration. Pulse spacings as small as 1 picosecond have been demonstrated corresponding to an effective data rate of up to one terahertz. An integrated optical pulse generator is configured to receive a laser light input and output an optical pulse train. Direct space-to-time pulse shaping and optical pulse train generation is achieved by use of an arrayed waveguide (AWG) that is double-passed. A mask is utilized for time domain pulse shaping that is employed after a single pass through the arrayed waveguide. In the case of an optical data/word generator, a spatially patterned mask translates spatial data, for example representing binary data or a binary word, of the mask to the output optical pulse train. The arrayed waveguide (AWG) system has waveguide ports that double as inputs and outputs, and provides direct space-to-time pulse shaping of a single, short pulse laser/optic signal. Direct optical access to individual guides in the waveguide array allows one to control the light intensity in each guide and therefore control the output pulse intensities with a one-guide one-pulse effect.
