DEVICE FOR MULTICAST OF OPTICAL SIGNALS IN THE INTERNET AND OTHER NETWORKS

摘要

Device is formed by electronic part and optical part (2). Electronic part consists of control module (4), interface module (3) formed by power supply block (31), block (32) for measuring basic operational parameters of the whole device and interface (33), and by power supply part (1). Power supply block (31) of interface module (3) is connected to power supply part (1), to optical part (2) and to control module (4). Interface (33) is connected to optical part (2) and to control module (4), and block (32) for measuring basic operational parameters of the whole device is connected to the power supply part (1) and to control module (4). To the control module (4) input/output interfaces are connected involving standard interface for communication with user and/or interface for communication in Ethernet network and/or interface via RS 232 and/or interface for communication via serial USB bus. Optical part (2) of the device is designed as double-stage. First stage (21) is formed by M passive wide-spectrum optical splitters (5), each of which is equipped with N outputs. Second stage (22) is realized by N wide-spectrum optical switches (6), each of which is equipped with M inputs.
