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.

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.

Abstract: Device for multicast of optical signals in the Internet and other networks is formed by an electronic part and an optical part. The electronic part consists of a control module, an interface module formed by a power supply block, a block for measuring basic operational parameters of the whole device and an interface, and by a power supply part. The power supply block of the interface module is connected to the power supply part, to the optical part and to the control module. The interface is connected to the optical part and to the control module, and the block for measuring basic operational parameters of the whole device is connected to the power supply part and to the control module. Input/output interfaces involving a standard interface for communication with a user and/or an interface for communication in an Ethernet network and/or an interface via RS 232 and/or an interface for communication via a serial USB bus are connected to the control module.
