Abstract: Modular kit of the spectrally flexible device for bidirectional transmissions of optical signals sensitive to timing in the Internet and other networks in the basic embodiment contains the source of the optical holding signal, which is electrically bi-directionally interconnected with the control electronics module. This source of the optical holding signal is optically interconnected is optically interconnected by its one output via the first isolator and the first wave-sensitive coupler with one optical input/output of the semiconductor optical amplifier and/or the second output of the source of the optical holding signal is interconnected via the second isolator and the second wave-sensitive coupler with the second optical input/output of the semiconductor optical amplifier. Semiconductor optical amplifier is electrically bi-directionally interconnected with the control electronics module, the input of which is connected to the output of the power supply module.

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.
