摘要： Apparatus for an optical communications network has optical paths for optical traffic, and optical ports, one of which is an unused output port. A security monitoring system has a blocking part coupled removably to the unused output port to occupy it to prevent unauthorized access. An optical detector can detect optical signals passing through the unused output port to the blocking part, and there is alarm circuitry configured to output an alarm signal based on the detecting of the optical signals. This monitoring can help make the node more secure from interference or from eavesdropping. By blocking the port, the monitoring can be independent of the type of signals on the optical paths. The system can be passive or active, and does not require a change in the installed node configuration and so can be added easily to existing infrastructure.

摘要： A wavelength multiplex transmission system wherein crosstalk between wavelengths can be reduced and hence signal degradation can be reduced. At a transmitting apparatus, a single input signal is differentially split into two signals, which are then converted into optical signals for wavelength multiplex transmission. If any crosstalk occurs in the wavelength multiplex transmission system, it is superimposed on those two optical signals in such a manner that it is uniformly superimposed on the signals of reversed polarities. At a receiving apparatus, therefore, the optical signals are converted into the electric signals, which are then differentially combined, with the result that the signal components are added together, while the crosstalk components are canceled. In this way, the degradation of optical signals caused by crosstalk can be reduced in the wavelength multiplex transmission system.

摘要： A system for passively scrambling and unscrambling a, pulse optical signal transmitted through a multi-mode optical fiber is provided. The system includes a scrambling unit connected between a signal receiving end of said transmission fiber and an optical signal source that includes an optical fiber which creates a differential delay between two groups of optical modes of the signal that is at least one bit period long such that said optical signal is passively scrambled, and an unscrambling unit connected to a signal transmitting end of said transmission fiber having an optical fiber that counteracts said differential delay between said two groups of optical modes of the signal such that said optical signal is passively unscrambled. The scrambling unit optical fiber has an alpha profile with a complementary perturbation that creates the differential delay between two groups of optical modes of the signal, and the unscrambling unit optical fiber has an alpha profile with reversal complementary perturbation that counteracts the differential delay between said two groups of optical modes of the signal. Alternatively, the scrambling and unscrambling units may have the combination of a mode splitter that splits the signal into two different groups of optical modes, and a pair of optical fibers that conduct the two groups of optical modes in parallel, the fibers being of different lengths to create or to counteract a differential delay in the two groups of modes.

摘要： Methods and apparatus for optical-power control in an optical network employing wavelength-division multiplexed (WDM) optical-fiber links are devised to circumvent the effect of crosstalk caused by optical-power scattering. Each carrier signal is amplitude- modulated by an identifying tone, with the power of an identifying tone having a predetermined ratio to the power of its carrier signal. A fiber span within an optical-fiber link is tapped at a preferred monitoring point, and the power spectrum of the envelope of the tapped optical signal is measured. To estimate an individual carrier power, a temporary gain is applied and the power of a corresponding tone is measured. To control optical power of each wavelength carrier in several spans in the network, a network controller selects an order of processing the spans of interest, and selects the order of processing of each channel within each span.
