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.
