Modular kit of devices is formed by an optical module (1) interconnected with a control electronic module (2) of the electronic system with two redundant power supply sources (25, 26), which is subsequently interconnected with the communication computer module (3) equipped with the user communication interface (31) and the machine communication interface (32). Optical module (1) has N optical inputs and M optical outputs where N and M are non-zero natural numbers, and in total the optical module (1) contains NxM of optical switching elements (110) to (113) 2x2 type Mach-Zender interferometer. Each of them has two optical inputs, two optical outputs and one electric input. Optical switching elements (110) to (113) are mutually interconnected in a grid. Control electronic module (2) is formed by NxM pulse-width modulators (210) to (213) connected via an interface module (23) to the communication computer module (3) and to the power supply distribution block (24), while each of the pulse-width modulators (210) to (213) is by its output connected to the input of one of NxM voltage drivers (220) to (223) relevant for such pulse-width modulators (210) to (213). Voltage drivers (220) to (223) are interconnected directly with the power supply distribution block (24). Output of each of these NxM voltage drivers (220) to (223) is connected to electric input of one of NxM optical switching elements (110) to (113). |
