Description
本發明係與光收發技術有關，尤指一種即使在線設備出現當機或電源供應中斷時仍可避免光纖網路斷線的光收發裝置。The present invention relates to optical transceiver technology, and more particularly to an optical transceiver capable of avoiding fiber network disconnection even when an online device is interrupted or the power supply is interrupted.
光收發器為光纖網路應用中所必備的裝置，係用在光訊號的通訊中，分別耦接在線設備（In-Line Equipment）與光纖網路設備，可輔助在線設備正常使用光纖網路。光收發器可透過光電轉換器（O/E Converter），將電氣訊號轉換成為光訊號並發送到光纖網路設備，也可將所收到的光訊號轉換為電氣訊號並傳送到在線設備。The optical transceiver is a necessary device in the optical fiber network application, and is used in the communication of the optical signal, and is respectively coupled to the in-line equipment (In-Line Equipment) and the optical network equipment, which can assist the online equipment to normally use the optical network. The optical transceiver can convert the electrical signal into an optical signal through an optical converter (O/E Converter) and send it to the optical network device. The received optical signal can also be converted into an electrical signal and transmitted to the online device.
一般的在線設備只需配置單一個光收發器，即能正常使用光纖網路，然有些用於提供資料過濾功能的例如流量管控裝置等在線設備則需要配置二個光收發器，並使該二個光收發器連接在二個光纖網路設備之間，當其中一個光收發器自光纖網路設備中接收到光訊號，必須經過該在線設備之後，才從另一個光收發器輸出，如此，一旦該在線設備斷電或當機，該二個光收發器之間的訊號就無法傳輸，則分別連接該二個光收發器的二個光纖網路設備之間便形成斷線。A typical online device only needs to be configured with a single optical transceiver, that is, the optical network can be used normally. However, some online devices such as a flow control device for providing data filtering functions need to configure two optical transceivers, and the second optical transceiver is required. An optical transceiver is connected between two optical network devices. When one of the optical transceivers receives the optical signal from the optical network device, it must pass through the online device before outputting from another optical transceiver. Once the online device is powered off or down, the signals between the two optical transceivers cannot be transmitted, and the two optical network devices respectively connected to the two optical transceivers form a disconnection.

The invention may also be embodied or applied by other different embodiments. The details of the present invention can be variously modified and changed without departing from the spirit and scope of the invention. [0001] First Embodiment [00016] Referring to FIG. 1, there is shown a block diagram of a first embodiment of an optical transceiver device of the present invention. As shown in FIG. 1, the optical transceiver device 3 of the present invention is used for connection construction.

The control component 21 is, for example, a central processing unit, and the preset time is transmitted through The control element 21 is provided, but not limited thereto, and the preset time can also be set through the processing element 342 (described in detail later). In addition, the optical transceiver 3 of the present invention mainly includes a first transceiver 31, a second transceiver 31', a first photoelectric conversion unit 32, a second optical conversion unit 32', an optical switching unit 33, a management unit 34, and a first The electrical signal 埠 35 and the second electrical signal 埠 35'. Hereinafter, the optical transceiver 3 of the present embodiment will be described in detail with reference to Figs. 2A and 2B. [00017] The first optical transceiver 31 is connected to the first optical network device 1 for receiving an optical signal from the first optical network device 1, or transmitting an optical signal to the first optical network device 1 . [00018] The second optical transceiver 31' is connected to the second optical network device 1' for receiving an optical signal from the second optical network device 1' or transmitting an optical signal to the second optical network. Road equipment 1'. [00019] The first photoelectric conversion unit 32 is configured to perform a conversion process on the optical signal received from the first optical transceiver 31 to generate and output an electrical signal, or convert the electrical signal received from the online device 2 into The optical signal is output to the first optical transceiver 31 for reception by the first optical network device 1. [00020] The second photoelectric conversion unit 32' is configured to perform a conversion process on the optical signal received from the second optical transceiver 31' to generate and output an electrical signal, or to receive an electrical signal from the online device 2. It is converted into an optical signal and output to the second optical transceiver 31' for reception by the second optical network device 1'. [00021] The optical switching unit 33 is connected to the first optical transceiver 31, the second optical transceiver 31', the first photoelectric conversion unit 32, and the second photoelectric conversion unit 32', respectively. For example, the optical switching unit 33 can be, for example, a non-locking optical switch. The management unit 34 is connected to the optical switching unit 33 and the online device 2 for monitoring the operating state of the online device 2. When the online device 2 is monitored to be normal, the optical switching unit 33 is sent to the optical switching unit 33. a first control command for causing the optical switching unit 33 to perform a normal mode. As shown in FIG. 2A, the first optical transceiver 31 is connected to the corresponding first photoelectric conversion unit 32, and the second optical transceiver 31' and the corresponding The second photoelectric conversion unit 32' is connected. When the online device 2 is detected to be abnormal, the online device 2 may be disconnected or the power is interrupted. At this time, the second control command is sent to the optical switching unit 33. In order to enable the optical switching unit 33 to perform the bypass mode, as shown in FIG. 2B, the first optical transceiver 31 is connected to the second optical transceiver 31' to realize the first and second optical transceivers 31, 31'. The optical signal transmission operation between the two ensures that the first and second optical network devices 1, 1' can maintain normal network communication. More specifically, the management unit 34 is comprised of a monitoring component 341 and a processing component 342. [00023] The monitoring component 341 is connected to the control component 21 to receive the zeroing signal output by the control component 21, and performs a timing operation. When the timing of the preset time is received, the zeroing signal output by the control component 21 is received. a first state signal is generated, and when the zeroing signal output by the control component 21 is not received at the preset time, a second state signal is generated, and the online device 2 is directly restarted via the control component 21 or The operating system, in this embodiment, the monitoring component 341 can be a Watch Dog Time (WDT) wafer. [00024] The processing component 342 is respectively connected to the control component 21, the monitoring component 341 and the optical switching unit 33. When the signal generated by the monitoring component 341 is converted from the second state signal to the first state signal, as shown in FIG. 2A. As shown, the processing component 342 can send a first control command to the optical switching unit 33 to connect the first optical transceiver 31 with the corresponding first photoelectric conversion unit 32. The second optical transceiver 31' corresponds to The second photoelectric conversion unit 32' is connected. At this time, the online device 2 can communicate with the first optical network device 1 and the second optical network device 1' through the optical switching unit 33, respectively. When the flow control device is used, if the flow rate between the first fiber optic network device 1 and the second fiber optic network device 1' exceeds a preset value, an abnormality occurs, and the online device 2 can also cut off the mechanism through the mechanism. The communication between the first and second fiber optic network devices 1, 1 ', in this embodiment, the processing component 342 can be a Complex Programmable Logic Device (CPLD). [00025] When the signal generated by the monitoring component 341 is converted from the first state signal to the second state signal, as shown in FIG. 2B, the processing component 342 can send a second control command to the optical switching unit 33. The first optical transceiver 31 is connected to the second optical transceiver 31' to realize an optical signal transmission operation between the first optical transceiver 31 and the second optical transceiver 31'. At this time, the optical switching unit 33 The connection between the first and second optical transceivers 31, 31' and the online device 2 is cut off, so that the optical network is not affected by the power failure or the crash of the online device 2, and the first optical network device 1 It is still possible to achieve and maintain normal network communication with the second fiber optic network device 1'. [00026] The first electrical signal 埠 35 is connected to the first photoelectric conversion unit 32 and the online device 2 respectively for providing transmission of electrical signals between the first photoelectric conversion unit 32 and the online device 2. [00027] The second electrical signal 埠 35' is respectively connected to the second photoelectric conversion unit 32 ′ and the online device 2 for providing a signal between the second photoelectric conversion unit 32 ′ and the online device 2 transmission. [00028] It should be noted here that the first electrical signal 埠35 and the second electrical signal 埠35' may be different or the same electrical signal 埠. When the optical switching unit 33 is configured as a lockable optical switch, when the processing component 342 sends the first or second control command to the optical switching unit 33, it only needs to send the signal of the control command once within a predetermined time, if the control is performed. The transmission of the signal and the electrical signal is on the same channel. Since the control signal is not transmitted on the channel for a long time, the mutual interference between the control signal and the electrical signal is not too large, but if the optical switching unit 33 is set When the optical switch is an unlocked optical switch, the processing component 342 needs to continuously send the control signal carrying the first or second control command to the optical switching unit 33, and if the control signal and the electrical signal are transmitted on the same channel for a long time. In this way, the inductance effect and the electrical signal between the control signal and the electrical signal will interfere with each other, and the influence on the transmission quality of the signal is very large. [00029] In the optical transceiver device 1 of the present invention, the processing component 342 transmits to the optical switching unit 33 a channel carrying the first or second control command control signal that does not occupy the transmission channel of the electrical signal (first The electrical signal 埠35 and the second electrical signal 埠35') are separate channels, in other words, the control signal is separated from the transmission channel of the electrical signal, so that different signals can be transmitted in the same channel to generate inductance. The effect is caused by the problem that the signals interfere with each other.

The unit 34' is configured to perform a timing operation, and when the zeroing signal output by the control component 21 is received at the timing of the preset time, the first state signal is generated, and the timing is at the preset time. 21 does not receive zero signal output of the control device, generating a second state signal, and 21 directly or restarting the online device 2 via the operating system control element. The processing unit 22 is connected to the management unit 34'. When the signal generated by the management unit 34' is converted from the second status signal to the first status signal, the processing unit 22 can send the first to the optical switching unit 33. a control command to connect the first optical transceiver 31 to the corresponding first photoelectric conversion unit 32, the second optical transceiver 31' is connected to the corresponding second photoelectric conversion unit 32, when the management unit 34' When the generated signal is converted from the first state signal to the second state signal, the processing component 22 can send a second control command to the optical switching unit 33 to enable the first optical transceiver 31 and the second optical transceiver 31.
