  • Patent number: 8582967
    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.
