摘要： An optical receiver configuration and method of controlling an optical signal receiver adjusts a decision threshold to reduce the bit error rate (BER). The receiver includes a comparator having a data input and a digital data output. An error detection & correction circuit provides an error signal representative of the number of corrected "1"s and "0"s in the data output from the comparator. Based on the error signal, a control circuit modifies the comparator decision threshold in a direction to reduce the BER of the receiver. Dynamic modification of the decision threshold may also be accomplished. A total percentage error indicator is preferably used as the basis of changing the decision threshold value. The total percentage error indicator may be used to variably adjust the decision threshold by an amount that varies according to the magnitude of the total percentage error indicator to thereby more quickly arrive at an acceptable decision threshold and prevent overshoot. A searching method may also be used to determine the usable range of the comparator before tuning the decision threshold-

摘要： An embodiment of the invention is a method of allocating protection path resources including defining a working path and obtaining a link vector for each of a plurality of protection paths. The link vector includes a plurality of link vector elements. A proposed link vector is determined for each of the protection paths. The proposed link vector includes a plurality of proposed link vector elements and is indicative of allocating a respective protection path to the working path. A maximum link vector element is determined and a maximum proposed link vector element is determined. A link cost is determined based on a difference between the maximum proposed link vector element and the maximum link vector element. A path cost is determined for at least two protection paths based on a sum of link costs associated with a respective protection path. One of the at least two protection paths having the minimum path cost is selected to provide protection for the working path.

摘要： An examplary embodiment of the invention is an optical communication network (Fig. 1) transmitting signals on multiple wavelengths. The network includes a first dispersion compensating fiber (18-1) providing dispersion compensation and dispersion slope compensation. The first dispersion compensating fiber has a first non-zero dispersion coefficient and a first non-zero dispersion slope coefficient. The network also includes a second dispersion compensating fiber (18-2) in optical communication with the first dispersion compensating fiber. The second dispersion compensating fiber has a second non-zero dispersion coefficient and a second non-zero dispersion slope coefficient. The lengths of first dispersion compensating fiber and second dispersion compensating fiber are selected to compensate dispersion and compensate dispersion slope in a transmission path in optical communication with the first dispersion compensating fiber and the second dispersion compensating fiber. The compensation of dispersion and dispersion slope in the transmission fiber path occurs simultaneously for multiple wavelengths. Alternate embodiments include a method of compensating dispersion in an optical communications network.

摘要： A database architecture and method of using a database is disclosed. The database is intended for use with a product stress testing system in which a large number of different modules may be subjected to a variety of stressors including environmental stressors and functional load testing. The database also enables a wide variety of test and communication equipment to be used in an efficient manner to test and communication with the module being tested. Generic commands may be translated to test and communication equipment specific command strings as well as module specific command strings. Data collected from these various devices by the stress testing system may also be parsed and stored in fields associated with the corresponding module being tested. The product table, result table, process table, and equipment command and communication tables are interrelated through defined data associations. These data entities and their mutual data relationships revolve around the module being subjected to the stress test. In this way the stress test results may be associated with the various products, the results may be mapped against product-specific test criteria, and generic commands may be translated to product-specific commands.

摘要： A transmitter (102,200) maps an N-bit sequence to a point selected from a four-dimensional (4D) constellation consisting of 2N points which form a subset of a Cartesian product of first and second two-dimensional (2D) constellations, the first constellation consisting of M1 points divided into first, second, and third points, and the second constellation consisting of M2 points divided into fourth, fifth, and sixth points, wherein M1, M2 ≥ 5, and wherein log2(M1×M2) > N. The subset includes any 4D point that is generated by combining any one of the M1 points and any one of the fourth points; includes any 4D point that is generated by combining any one of the first points and any one of M2 points; and excludes any 4D point that is generated by combining any third point and any sixth point. An optical signal (204) representing the selected point is transmitted to a receiver (104,300).

摘要： An optical modulator (410) includes multiple segments (420, 430, 440) including modulator segments (430, 440) and a Radio Frequency (RF) crossing segment (420) where RF lines (+S, - S) extending a length of the modulator (410) cross one another. The present disclosure includes optimization of one or more of a geometry of the RF crossing segment (420) and a location of the RF crossing segment (420) along the length. The geometry is selected so that the RF crossing segment (420) appears as another segment having similar characteristics as modulator segments (430, 440)). The location of the RF crossing segment (420) is selected to balance out fabrication error and phase efficiency.
