    • Between two nodes, data in the form of two different signals are transmitted bidirectionally, in accordance with IEEE1394 through one optical fiber cable. At the time of data transmission, data of two different signals is converted to data of one type of signal at one node, and transmitted to the optical fiber cable, and at the other node, the data received from the optical fiber cable is converted to the original data of two different signals, and transmitted to a subsequent processing circuit in accordance with IEEE1394. At this time, in a transmission sequence for requesting and granting priority of transmission over the optical fiber cable between both nodes, the priority of transmission is granted alternately to both nodes.

    • A transmission method uses multiple kinds of control codes to be exchanged on a serial transmission path between a sender side and a receiver side, and each of the multiple kinds of control codes has bits smaller in number than a predetermined fixed length. The transmission method includes the steps of inspecting the received bit string in groups of bits of the number of the control code, and thereby determining whether one of the multiple kinds of control codes is present in the serial signal received on the serial transmission path or not, selecting the control code to be sent based on a result of the determination in the determining step, sending, onto the serial transmission path, a bit string containing at least the control code to be sent based on the result of the determination in the determining step, and receiving the data code by inspecting the received bit string in groups of bits of the fixed length in response to the detection of the control code indicating the start of transmission of the data from the opposite side in the determining step.

    • In optical two-way communication using a single optical fiber, part of the light transmitted from an apparatus is received as stray light by the apparatus itself. This occasionally hampers accurate detection of disconnection from the partner apparatus and of the start of data communication by the partner apparatus after the establishment of connection. To overcome this, the timing with which an apparatus transmits a tone signal after the establishment of connection is compared with the timing with which the apparatus receives a tone signal from the partner apparatus, and the two apparatuses use different sets of data transmission properties (for example, different wavelengths) to accurately detect disconnection. Moreover, based on the properties of the received light and the characteristics of the receiving amplifier, repetition of the same code for longer than a predetermined period is detected to accurately detect disconnection. Furthermore, in response to a request for data communication after the establishment of connection, a tone signal having a different pattern from that used to establish connection is used to accurately detect the start of data communication.
    • 在使用单个光纤的光学双向通信中,从设备发射的光的一部分被设备本身作为杂散光接收。 偶尔会妨碍对方设备断开连接的准确检测,以及对方设备建立连接后的数据通信开始。 为了克服这个原因,将在连接建立之后将设备发送音调信号的定时与设备从对方设备接收到音调信号的定时进行比较,并且两个设备使用不同的数据传输属性集(对于 例如,不同的波长)以精确地检测断开连接。 此外,基于接收光的特性和接收放大器的特性,检测出长于预定周期的相同代码的重复以精确地检测断开。 此外,响应于在建立连接之后的数据通信请求,使用具有与用于建立连接的模式不同的模式的音调信号来精确地检测数据通信的开始。
