    • Data 12010, 12020, etc. to be sent to each of client devices 1201, 1203, etc. from a data server device 1000 are, in a data communication unit 1100, first divided into electric signal packets by a data transmission/receipt control unit 1140, whereby an electric signal sequence tag is added to each electric signal packet, then converted into optical packets 12011, 12021, etc. by an optical signal transmitting unit 1120, and transmitted through an optical signal path 1110. At optical switch 1101, the optical paths of the packets are switched to optical signal paths 1111, 1112, etc. by the actions of optical destination tags 12111, 12121, etc. that are respectively synchronized with optical packets and irradiated by an optical signal transmitting unit 1120. At optical signal receiving units 1131, 1132, etc., the received optical packets are converted to electric signal packets, and reassembled to be original data 12010, 12020, etc. according to the identification information on the reassembly sequence recorded in the sequence tag in an electric signal packet by data transmission/receipt control units 1141, 1142, etc., and distributed to client devices 1201, 1202, etc. as electric signals.
    • 要从数据服务器装置1000发送到每个客户机装置1201,1203等的数据12010,12020等在数据通信单元1100中首先被数据发送/接收控制单元划分成电信号包 1140,由此将电信号序列标签添加到每个电信号包,然后由光信号发送单元1120转换成光分组1201​​1,12021等,并通过光信号路径1110发送。在光开关1101处, 通过分别与光分组同步并由光信号发射单元1120照射的光目的地标签12111,12121等的动作将分组的光路切换到光信号路径1111,1112等。在光信号 接收单元1131,1132等,接收到的光分组被转换为电信号分组,并根据加密的识别信息重新组合为原始数据12010,12020等 通过数据发送/接收控制单元1141,1142等记录在电信号包中的序列标签中的mbly序列,并作为电信号分发给客户端设备1201,1202等。
