摘要： An optical packet switch switches optical packets according to bit-rates at which the optical packets are provided. For example, optical packets that are received at similar bit-rates may be routed to a destination at separate time slots over a single channel wavelength, and optical packets that are received at different bit-rates may be routed to the destination over separate channel wavelengths. When optical packets are provided at different bit-rates on a plurality of input paths, optical packets provided at low bit-rates may be compacted before switching to the destination. Alternatively or additionally, the bit-rates of the optical packets may be balanced before switching to the destination. Bandwidth contention among optical packets may be resolved by polarizing optical packets originating from separate input paths in different polarization directions, and merging optical packets having different polarization directions onto a single switched channel wavelength. Compaction of optical packets may alternatively be employed for resolution of bandwidth contention. Related apparatus and methods are also described.

摘要： An optical switching apparatus in an optical communication network selectively combines and separates, using OTDM and/or WDM, optical signal samples that are obtained by a spread spectrum technique or a combination of optical signal samples that are obtained by a spread spectrum technique and optical signal samples that are carried over discrete channel wavelengths. In upstream communication, when optical signal samples that are received at the optical switching apparatus include upstream optical signal samples that are obtained by a spread spectrum technique, the optical switching apparatus optically converts the optical signal samples provided thereto into a broadband combined series of upstream optical signal samples and routes the broadband combined series of upstream optical signal samples to a destination route. In downstream communication, when the optical switching apparatus receives a broadband series of downstream optical signal samples obtained by utilizing a spread spectrum technique, the optical switching apparatus optically converts the broadband series of downstream optical signal samples into an integer number nn>1 of series of downstream optical signal samples that include at least one of the following: broadband series of downstream optical signal samples; and series of downstream optical signal samples having the downstream optical signal samples carried over discrete channel wavelengths. The nn series of downstream optical signal samples are then routed to nn routes respectively. Related apparatus and methods are also described.

摘要： The present invention provides for an improvement in communication performance of an optical communication system which communicates data via N different channel wavelengths using WDM. In a case that not all of the N channel wavelengths are carrying data simultaneously, a switching unit may route data signals to selected channel wavelengths, selected to increase channel spacing between as many as possible channel wavelengths. In a case that time dependent changes, such as temperature changes, cause degradation in communication performance, channel hopping may be performed. Alternatively or additionally, a data rate reduction of data carried over interfered channels may be also performed. In a case that actual capacities of at least some of the N channels are lower than a maximum attainable channel capacity, channel condensation may be performed. The present invention also provides for a system combining channels at a bandwidth between 1.52 micrometer and 1.62 micrometer with a channel operating at 1.31 micrometer.

摘要： An optical communication technique transmits an optical signal at a higher bit rate using an optical transceiver interface couplable to a set of optical transmitters, each operating at a lower bit rate over a plurality of channels, by demultiplexing the optical signals from the transmitters such that some of the resulting optical signals have wavelengths that are specified as center wavelengths by an optical communication standard for the lower bit rate optical transmission and the rest of the resulting optical signals have wavelengths offset from the specified center wavelengths, then multiplexing the resulting optical signals into the higher bit rate optical signal. Related optical communication techniques involve using the reciprocal method to receive the higher bit rate optical signal and to produce multiplexed optical signals at the lower bit rate.
