Abstract:
Modular set is formed by optical module interconnected with control module of electronic system. Optical module is formed by at least two pairs of laser diodes connected in series and including Peltier cooler and thermistor, which are connected to inputs of polarizing fiber combiners, and depolarized outputs of these polarizing fiber combiners are connected to inputs of a wavelengths combiner. Module of the electronic system is formed by a control microprocessor interconnected with direct current power supply source, with PID regulators of laser diodes temperature, a display indicating temperature of individual laser diodes and current flowing through them, and a control panel. To the microprocessor of the module of the electronic system is connected a gate array and to this gate array are connected generators of current impulses, which do not overlap in time, and their widths, repetition frequencies and amplitudes are adjustable, while the number of generators of current impulses equals to the number of pairs of laser diodes and their outputs are connected via power stages to pairs of laser diodes connected in series, and where to the power stages is connected an analogue/digital converter, which is connected also to the microprocessor.

Abstract:
Modular kit of devices for variable distribution, mixing and monitoring of optical signals in the Internet and other networks is formed by an optical module interconnected with a control electronic module of the electronic system with two redundant power supply sources, which is subsequently interconnected with the communication computer module equipped with the user communication interface and the machine communication interface. Optical module has N optical inputs and M optical outputs where N and M are non-zero natural numbers, and in total the optical module contains N×M of 2×2 type Mach-Zender interferometer optical switching elements. Each of them has two optical inputs, two optical outputs and one electric input. Optical switching elements are mutually interconnected in a grid. Control electronic module is formed by N×M pulse-width modulators connected via an interface module to the communication computer module and to the power supply distribution block.
