Abstract:
Modular set is formed by optical module (1) interconnected with control module (2) of electronic system. Optical module (1) is formed by at least two pairs (10, 11, 12, 13) of laser diodes connected in series and including Peltier cooler and thermistor, which are connected to inputs of polarizing fiber combiners (14, 15, 16, 17), and depolarized outputs of these polarizing fiber combiners are connected to inputs of a wavelengths combiner (18). Module (2) of the electronic system is formed by a control microprocessor (20) interconnected with direct current power supply source (21), with PID regulators (25) of laser diodes temperature, a display indicating temperature of individual laser diodes and current flowing through them, and a control panel. To the microprocessor (20) of the module (2) of the electronic system is connected a gate array (22) and to this gate array (22) are connected generators (23) of current impulses, which do not overlap in time, and their widths, repetition frequencies and amplitudes are adjustable, while the number of generators (23) of current impulses equals to the number of pairs (10-13) of laser diodes and their outputs are connected via power stages (24) to pairs (10-13) of laser diodes connected in series, and where to the power stages (24) is connected an analogue/digital converter (210), which is connected also to the microprocessor (20).
Abstract:
Device is formed by electronic part and optical part (2). Electronic part consists of control module (4), interface module (3) formed by power supply block (31), block (32) for measuring basic operational parameters of the whole device and interface (33), and by power supply part (1). Power supply block (31) of interface module (3) is connected to power supply part (1), to optical part (2) and to control module (4). Interface (33) is connected to optical part (2) and to control module (4), and block (32) for measuring basic operational parameters of the whole device is connected to the power supply part (1) and to control module (4). To the control module (4) input/output interfaces are connected involving standard interface for communication with user and/or interface for communication in Ethernet network and/or interface via RS 232 and/or interface for communication via serial USB bus. Optical part (2) of the device is designed as double-stage. First stage (21) is formed by M passive wide-spectrum optical splitters (5), each of which is equipped with N outputs. Second stage (22) is realized by N wide-spectrum optical switches (6), each of which is equipped with M inputs.
