Abstract: A method and an apparatus are provided for safely testing an autotransformer of power distribution lines which has an identified centre tap ground connector, a primary winding terminal and a secondary winding terminal. The method for safely testing the autotransformer includes the steps of disconnecting the terminals and connector of the autotransformer from the distribution lines, applying a first testing AC voltage having a maximum value of substantially one volt only between a first of the terminals and the ground connector, measuring a first value of an AC voltage between the first terminal and the ground connector, and measuring a second value of an AC voltage between the second of the terminals and the ground connector. Thereafter, the method includes the steps of applying a second testing AC voltage having a maximum value of substantially one volt only between the second terminal and the ground connector, measuring a third value of an AC voltage between the second terminal and the ground connector, and measuring a fourth value of an AC voltage between the first terminal and the ground connector. Then, the method further includes steps of comparing the four measured values to predetermined constants, and generating corresponding signals indicating that autotransformer is short-circuited or that the same is open-circuited. When, the autotransformer being test is not short-circuited nor open-circuited, the method includes the step of generating a signal indicating that the first terminal is the secondary winding terminal or the first terminal is the primary winding terminal, whereby the primary and secondary terminals are clearly identified.

Abstract: A fiber optic access node has input and output fibers terminating at a housing. A module is retractably insertable into the housing to automatically lock into a position in which an output zone of the module aligns with the output fiber and input zone of the module aligns with the input fiber. The input and output zones may be those of fiber optic passive elements such as a bypass fiber, a fiber tap, a fiber extension loop or a wavelength division multiplexed device, or may be those of an active element such as a repeater incorporating a light emitter, a light detector and a control circuit. The fiber optic element may be encapsulated within a plastics block or can be clamped between two plates. The combination of module and housing allows rapid and easy substitution of fiber optic functions within a fiber network.

Abstract: A binary data signal is regenerated with respect to three threshold levels, one of which is derived from and lies between the other two so that it is an optimum level for producing a regenerated output signal. Two control loops are used to produce the other two threshold levels to produce regenerated signals with predetermined error rates, the errors occurring on the two control loops for the two respective states of the binary data signal, whereby the optimum threshold level is maintained regardless of the nature of signal degradation. The arrangement provides rapid performance monitoring which can also be used to adjust other parameters, such as detector bias, equalizer tuning, and clock phase, for optimum performance in an active and ongoing manner.

Abstract: A fiber optic star coupler particularly for use in providing optical interconnects between circuit boards has a light mixer into which input and output fibers are inserted. The mixer has rectangular cross-section passage, an interior surface of which is highly reflecting. The mixer is long enough to promote a degree of internal reflection of light from any one of the input fibers sufficient that the corresponding light intensity reaching the output fibers is substantially uniform. In an optical interconnect arrangement, interconnection between circuit boards in a rack or cabinet is achieved by mounting light emitting and light receiving units on each board and leading fibers to which the units are fixed to the fiber optic star coupler so that light from the emitter units enters one end of the light mixer and fibers leading to the receiver units enter the opposed end of the light mixer. The fiber optic star coupler is substantially cheaper and more easily manufactured than known fiber optic star couplers using a polished glass slab as a light mixer.

Abstract: The modal-insensitive coupler consists of a number N of optical multimode fiber lengths, each fiber length having a core of initial predetermined cross-sectional area. The fiber lengths are fused together in a coupling section such that the cores of the fiber lengths have a reduced cross-sectional area in the coupling section which supports a minimum number of modes of optical energy at a predetermined wavelength, and such that the fiber lengths have different core cross-sectional areas to produce preselected coupling ratios.

Abstract: A method of making highly reflective mirrors on a wafer in the manufacture of photonic devices involves preheating a wafer to remove adsorbed volatile contaminants at a temperature between about 300 and 600° C. The wafer surface is etched at a temperature between about 300 and 600° C. to remove absorbed and chemically absorbed contaminants in the presence of a plasma to prevent poisoning. The wafer surface is thoroughly cooled so as to as reduce the surface mobility of the impinging atoms during the subsequent metallic deposition. A deposition is then carried out on the cooled wafer of a gettering layer for gettering hydrogen, oxygen and nitrogen. A metallic reflective layer is then deposited in a deposition chamber, and finally the wafer is removed from the deposition chamber to prevent excessive bulk oxidation.

Abstract: There is described a method and system for inputting/outputting multiple data streams of variable widths. Input/output pins are grouped together via a plurality of transfer blocks, each transfer block being controlled by an independent clock. Data streams can therefore be input/output using asynchronous clocks. Two data streams can also be input/output on a single pin using the rising and falling edge of the clock.
