There are many potential safety hazards in internet network, such as DOSS attack, virus, trojan horse, junk mail, etc., which have great influence on the normal network life of the public. In order to effectively deal with the network security threat and eliminate the network security hidden trouble, the network optical interface module 100 needs to be deployed in the network, and the network optical interface module 100 can effectively deal with the network security threat, eliminate the network security hidden trouble, perform security protection on the network, monitor and analyze abnormal network traffic, take corresponding measures in time, and increase the security of the network. Specifically, the network optical interface module 100 may select a unified threat Management module (UTM), an Intrusion Prevention System (IPS), a Distributed denial of service attack (DOSS) module, a Deep Packet Inspection (DPI) module, or the like. Due to the addition of the protection device (i.e., the network optical interface module 100) in the network link, when the device fails, the communication network is inevitably interrupted, which may cause other network problems. Therefore, it is also necessary to install a BYPASS (BYPASS) device 200 in the network at the same time.

Based on this, the present disclosure proposes a bypass device, the bypass device 200 has two modes, namely, a non-bypass mode and a bypass mode, and the bypass mode is a protection mode based on a physical link. As shown in fig. 1, under normal conditions, the bypass apparatus 200 is in an initial state, that is, in a non-bypass mode, a normal optical link 102 is formed between an external optical path and a main board 101 of a main device (i.e., the network optical interface module 100), and traffic is processed by the main device (i.e., the network optical interface module 100) and then sent to a downlink device; as shown in fig. 2, in case of an abnormal condition (such as power failure) of the main device, the bypass apparatus 200 switches to the bypass mode, enters the bypass state, the external optical path forms the bypass optical link 103 through the bypass apparatus 200, that is, the traffic is directly sent to the downlink device without passing through the main device, and the bypass apparatus 200 is configured to avoid network interruption when the main device is abnormal.

Fig. 3 shows a bypass apparatus 200 proposed by the present disclosure, which is used for a network optical interface module 100 (i.e. one of the aforementioned main devices), where the network optical interface module 100 has a plurality of external interfaces 201.

The external interface 201 is used for connecting with an external optical fiber 204 link, and the external interface 201 may be an optical fiber inlet of the network optical interface module 100 itself; the optical fiber may also be used as an optical fiber inlet of the bypass device 200 disposed in the network optical interface module 100, in which case the main board 101 of the network optical interface module 100 is connected to the external optical fiber 204 link through the bypass device 200.

The bypass device 200 includes: a plurality of optical modules 202, the plurality of optical modules 202 being used for photoelectric conversion and electro-optical conversion, the plurality of optical modules 202 corresponding to the plurality of external interfaces 201.

The plurality of optical modules 202 correspond to the plurality of external interfaces 201, so that each external interface 201 forms a corresponding normal optical link 102 to its corresponding optical module 202, specifically, each optical module 202 has an optoelectronic end and an optoelectronic end, the external interface 201 has a receiving end RX and a transmitting end TX, the receiving end RX of the external interface 201 is connected to the optoelectronic end of its corresponding optical module 202, so as to form an optical signal input channel, the optoelectronic end of the optical module 202 is connected to the transmitting end TX of its corresponding external interface 201, so as to form an optical signal output channel, the optical signal input channel and the optical signal output channel constitute the above normal optical link 102, and when an optical signal is transmitted in the above normal optical link 102, the optical signal is input to the optical module 202 from the outside through the input channel, and is output from the optical module 202 to the outside through the output channel. The optical module 202 is capable of performing optical-to-electrical conversion (optical-to-electrical end is used for implementation) and electrical-to-optical conversion (electrical-to-optical end is used for implementation), so as to transmit an optical signal in the normal optical link 102 (specifically, in an optical signal input channel) to another device (for example, the network optical interface module 100) in the form of an electrical signal, or transmit an electrical signal input by another device (for example, the network optical interface module 100) in the form of an optical signal in the normal optical link 102 (specifically, in an optical signal output channel).

And the optical switch 203 is arranged between the plurality of optical modules 202 and the plurality of external interfaces 201, is respectively connected with the plurality of optical modules 202 and the plurality of external interfaces 201 through optical fibers 204, and is used for forming optical links between different external interfaces 201, namely forming a bypass optical link 103.

Where optical switch 203 is a device that switches optical signals from one fiber line to another, it functions similarly to an electronic switch in an electronic circuit; the basic principle is that the movable optical fiber 204 itself or movable prism, reflector and lens intermediate are used for conversion, so that a certain optical path is switched on and a certain optical path is switched off; the optical module 202 may be a Small Form-factor Pluggable (SFP) or a Small gigabit ethernet interface Converter (SFP +), a gigabit ethernet interface Converter (GBIC), or the like. Fig. 4 shows a specific form of the internal structure of the optical switch 203, which has a first normal channel from the first input Port1 to the fourth input Port4, a second normal channel from the fourth output Port4 'to the first output Port 1', a third normal channel from the second input Port2 to the third input Port3, and a fourth normal channel from the third output Port3 'to the second output Port 2'. In an initial state of the optical switch 203, the optical switch 203 communicates with one external interface 201 and one optical module 202 through a normal optical link 102 composed of a first normal channel and a second normal channel, and communicates with another external interface 201 and another optical module 202 through a normal optical link 102 composed of a third normal channel and a fourth normal channel; then, the optical module 202 performs photoelectric conversion on the optical signal in the input channel and inputs the optical signal to a host device (for example, the network optical interface module 100), and the optical module 202 also performs photoelectric conversion on an electrical signal output by the host device (for example, the network optical interface module 100) and inputs the electrical signal to an output channel, so that the optical module 202 completes connection from the input channel to the output channel through the host device (for example, the network optical interface module 100) to form a complete optical link with both input and output functions, where the optical link is formed when the optical switch 203 supplies power normally, or the network optical interface module 100 operates normally (at this time, power supply of the network optical interface is inevitably normal); the optical switch 203 may also form an optical link between different external interfaces 201 by changing the optical path (i.e. forming the Bypass optical link 103), so that the optical link is directly output from another external interface 201 after entering the optical switch 203, thereby bypassing the master device, which is in the Bypass mode (i.e. Bypass mode), the optical link is formed when the optical switch 203 is powered abnormally, or the network optical interface module 100 is powered abnormally (at this time, the operation of the network optical interface module 100 is inevitably abnormal), at this time, the optical signal is directly transmitted from one external interface 201 to another external interface 201, thereby forming a Bypass with respect to the optical module 202, taking the internal structure of the optical switch 203 shown in fig. 4 as an example, in the Bypass mode, the first input Port1 is communicated with the second input Port2 (as shown by the dotted line in the figure), the first output Port1 'is communicated with the second output Port 2' (as shown by the dotted line in the figure), a bypass optical link 103 is thus established between the two external interfaces 201; meanwhile, the fourth input Port4 is communicated with the third input Port3 (as shown by the dotted line), and the fourth output Port4 'is communicated with the third output Port 3' (as shown by the dotted line), so that an optical link is correspondingly established between the two optical modules 202.

In the embodiment of the present disclosure, when the network optical interface module 100 fails, the optical switch 203 can avoid interruption of the communication network through the bypass mode, thereby improving the stability of the connection of the communication network, avoiding the situation of traffic non-continuity of the communication network, and improving the robustness of the system in which the communication network is located. Moreover, the plurality of external interfaces 201 of the network optical interface module 100 are respectively connected with the optical switch 203 through the optical fiber 204, the bypass device 200 is integrated in the network optical interface module 100, and the external end of the network optical interface module 100 only needs to be connected with the optical fiber 204, so that the operation is convenient, and the network optical interface module 100 has the advantages of miniaturization, integration, high concentration and the like.

The bypass device 200 provided by the present disclosure integrates the optical switch 203 and the optical module 202, and the bypass device 200 is directly connected with the external optical fiber 204 through the external interface 201, so that the compactness of the device and the convenience of assembly production are improved.

In some embodiments of the present disclosure, the bypass device 200 further comprises an integrator; the plurality of optical modules 202 are all disposed in an integrator, and the integrator is detachably connected to the main board 101 of the network optical interface module 100. The optical module 202 is required to establish electrical connection with the network optical interface module 100, and can convert an optical signal transmitted from the external interface 201 to the optical module 202 into an electrical signal and transmit the electrical signal to the network optical interface module 100, or convert an electrical signal sent by the network optical interface module 100 into an optical signal and transmit the optical signal to the corresponding external interface 201; during the process of connecting and detaching the optical module 202 of the bypass device 200 with different network optical interface modules 100 for multiple times or connecting and detaching the optical module 202 with the same network optical interface module 100 for multiple times, damage is easily caused, which causes poor contact, performance degradation or complete damage of the optical module 202; the plurality of optical modules 202 of the bypass device 200 are integrated into the integrator, and the connection between the plurality of optical modules 202 in the integrator and the motherboard 101 of the network optical interface module 100 can be realized by the connection between the integrator and the motherboard 101 of the network optical interface module 100, and similarly, the detachment between the plurality of optical modules 202 in the integrator and the motherboard 101 of the network optical interface module 100 can be realized by the detachment between the integrator and the motherboard 101 of the network optical interface module 100, in the above-mentioned multiple connection and disconnection processes, only the connection and disconnection between the integrator and the main board 101 of the network optical interface module 100 are involved, and the optical module 202 is always positioned in the integrator without any disassembly action, so the integrator avoids the optical module 202 from being damaged when being connected and disassembled for many times, the service life of the bypass device 200 is prolonged, the utilization rate of the bypass device 200 is improved, and the cost is further saved. Most of the existing built-in bypass devices 200 are integrated and cured in the equipment (i.e., the network optical interface module 100), when the equipment needs to be replaced, only the whole equipment (obviously including the built-in bypass device 200 cured in the equipment) can be removed from the communication network, that is, the traffic cannot be normally transmitted from the upstream equipment to the downstream equipment, and the network is interrupted; that is, only the network can be interrupted to replace the device with the built-in bypass apparatus 200, and the bypass apparatus 200 of the present disclosure can be detachably connected to the motherboard 101 of the network optical interface module 100 through the integrator, and the optical switch 203 in the bypass apparatus 200 can form an optical link between different external interfaces 201, when the device (i.e., the network optical interface module 100) needs to be replaced, the bypass apparatus 200 is detached from the motherboard 101, and an optical link is formed between different external interfaces 201, and then the bypass apparatus 200 is connected to the motherboard 101 of a new device, so as to complete the replacement of the device, and the network does not need to be interrupted in the replacement process, thereby facilitating the operation and effectively saving the installation space of the network optical interface module 100. The specific integrator can select the cage of the optical module 202 to connect with a Physical layer (PHY) of a port of the main board 101; in addition, the integrator can integrate other components (i.e., the optical switch 203 and the optical fiber 204) of the bypass device 200 while integrating the optical module 202, so that the bypass device 200 is in a form of a board module, and only needs to be plugged and unplugged when being connected and detached with the motherboard 101.

As shown in fig. 5, in some embodiments of the present disclosure, the network optical interface module 100 further includes a connector 206, and the first power supply 104 is further provided in the network optical interface module 100, where the connector 206 is used to form an electrical connection between the first power supply 104 and the optical switch 203, so that the first power supply 104 supplies power to the optical switch 203. The optical switch 203 can change the direction of the optical fiber 204 line where the external interface 201 is located, the working energy of the optical switch is from electric energy, when the integrator is connected with the network optical interface module 100, the connector 206 also completes the electrical connection between the first power supply 104 and the optical switch 203, that is, the first power supply 104 can supply power to the optical switch 203, when the optical switch 203 normally supplies power, an optical link can be formed between the external interface 201 and the optical module 202 corresponding to the external interface 201, and when the power supply of the optical switch 203 is abnormal, an optical link can be formed between different external interfaces 201.

As shown in fig. 6, in some embodiments of the present disclosure, a controller 207 is further included, and the controller 207 is connected to the optical switch 203 and configured to control the optical switch 203 to establish an optical link between different external interfaces 201 according to an electrical signal of the first power source 104. The optical switch 203 determines the establishment mode of the optical link according to whether the power supply of the optical switch is normal or not, the specific control needs to be completed by the controller 207, the controller 207 determines whether the power supply of the optical switch 203 is normal or not by obtaining the electrical signal of the first power supply 104, for example, the electrical signal of the first power supply 104 is normal, the power supply of the optical switch 203 by the first power supply 104 is natural and normal, when the electrical signal of the first power supply 104 is abnormal, the power supply of the optical switch 203 by the first power supply 104 is natural and abnormal, and after the controller 207 determines that the power supply of the optical switch 203 is normal or abnormal, the optical switch 203 is controlled to establish the corresponding optical link. The controller 207 may be a Complex Programmable Logic Device (CPLD), which has a larger scale, a more complex structure, a higher processing and operation capability, and a higher control effectiveness and stability than a conventional programmable array logic device (PAL) and a generic array logic device (GAL).

In some embodiments of the present disclosure, a voltage detection circuit 208 is further included, the voltage detection circuit 208 is respectively connected to the first power supply 104 and the controller 207, and the voltage detection circuit 208 is configured to detect the voltage of the first power supply 104 and send the detection result to the controller 207. The electrical signal of the first power source 104 can be determined by the voltage thereof, and if the voltage thereof is maintained within the normal power supply voltage range, it can be determined that the electrical signal of the first power source 104 is normal, and if the voltage thereof deviates from the normal power supply voltage range, it can be determined that the electrical signal of the first power source 104 is abnormal. After receiving the detection result of the voltage detection circuit 208, the controller 207 may determine whether the electrical signal of the first power supply 104 is normal, and then control the optical switch 203 to establish a corresponding optical link according to the determination result.

In some embodiments of the present disclosure, a second power source 205 is further included, the second power source 205 is electrically connected to the optical switch 203 and the controller 207, and the controller 207 is further configured to control the second power source 205 to supply power to the optical switch 203 according to an electrical signal of the first power source 104. The power supply of the bypass device 200 is entirely dependent on the first power supply 104 of the network optical interface module 100. It has been described hereinbefore that the controller 207 controls the optical switch 203 in the following manner: if the electrical signal of the first power source 104 is normal, the optical switch 203 establishes an optical link between the external interface 201 and the corresponding optical module 202, and if the electrical signal of the first power source 104 is abnormal, the optical switch 203 establishes an optical link between different external interfaces 201. The way of the optical switch 203 to establish the optical link depends on the first power supply 104, as long as the electrical signal of the first power supply 104 is abnormal, the optical switch 203 cuts off the optical link between the external interface 201 and the optical module 202, establishes the optical link between different external interfaces 201, and forcibly changes the optical link, which often causes loss of service data in the original optical link and irretrievable loss. The second power supply 205 is controlled by the controller 207, so that the optical switch 203 can be powered by the second power supply 205 when the electrical signal of the first power supply 104 is abnormal, and the controller 207 can not control the optical switch 203 to switch the optical link to the bypass state at this time when the electrical signal of the first power supply 104 is abnormal, so that the optical switch 203 keeps the normal optical link state, thereby avoiding data loss caused by the forced switching of the optical link to the bypass state when the first power supply 104 is abnormal, ensuring the safety of data, and improving the safety of a network. Furthermore, when the device is replaced, if the service data in the normal optical link 102 between the external interface 201 and the optical module 202 needs to be reserved, when the connection between the integrator and the motherboard 101 of the network optical interface module 100 is detached, the power supply of the optical switch 203 is switched from the first power supply 104 to the second power supply 205, at this time, although the optical link between the external interface 201 and the optical module 202 is disconnected, a new optical link is not established between different external interfaces 201, so that after the integrator is connected with the motherboard 101 of a new network optical interface module 100, the optical link between the external interface 201 and the optical module 202 is reestablished, at this time, the original service data can be continuously transmitted, in this way of replacing the device, the optical switch 203 is always kept in a power-on state in the whole process, and non-inductive migration is realized.

In some embodiments of the present disclosure, the second power source 205 is further connected to the first power source 104, and the controller 207 is further configured to control the first power source 104 to charge the second power source 205 while the first power source 104 is supplying power to the optical switch 203. The second power source 205 can be a button lithium battery or a lithium manganese button battery, the electric quantity of the second power source 205 is limited and is only used as a supplementary power source when the first power source 104 fails, the second power source 205 is arranged inside the bypass device 200 and is preferably arranged inside the integrator and is connected with the first power source 104 through the connector 206, and when the electric signal of the first power source 104 is normal, the first power source supplies power to the second power source 205 so as to charge the second power source 205, thereby ensuring that the second power source 205 is in a full-power state at any time, avoiding the disassembly of the bypass device 200 due to the replacement of the battery, saving manpower and material resources, and improving the utilization rate of the second power source 205.

As shown in fig. 7, in some embodiments of the present disclosure, a preset value is stored in the controller 207; in response to the controller 207 determining that the electrical signal is abnormal according to the detection result and the preset value is the first set value, controlling the second power source 205 to supply power to the optical switch 203; in response to the controller 207 determining that the electrical signal is abnormal according to the detection result and the preset value is the second set value, the optical switch 203 is controlled to establish an optical link between different external interfaces 201. As described above, when the first power supply 104 fails, the controller 207 can control the optical switch 203 to establish an optical link between different external interfaces 201 (i.e. the bypass apparatus 200 is in the bypass mode), and can also control the second power supply 205 to optically supply power to the optical switch (i.e. the bypass apparatus 200 is in the non-bypass mode), and the existing bypass apparatus 200 cannot autonomously select its operation mode, i.e. cannot autonomously select the bypass mode or the non-bypass mode when the first power supply 104 fails; the controller 207 in the bypass device 200 provided in the present disclosure can autonomously select an operation mode by using a preset value stored therein, that is, different set values correspond to different operation modes, for example, the first set value may be 1, the second set value may be 0, that is, when the controller 207 obtains an abnormal electrical signal of the first power source 104, the preset value stored therein may be automatically identified, if the preset value is 1, the controller 207 controls the bypass device 200 to start a non-bypass mode, that is, controls the second power source 205 to supply power to the optical switch 203, and if the preset value is 0, the controller 207 controls the bypass device 200 to start a bypass mode, that is, controls an optical link to be established between different external interfaces 201. By storing the preset value in the controller 207, the handling mode of the bypass device 200 when the first power supply 104 fails can be set in advance, so that the capability of the bypass device 200 in handling the failure is improved, and the safety of service data in the network is ensured.

In some embodiments of the present disclosure, the controller 207 may further be capable of being connected to the interactive terminal, and the controller 207 is configured to obtain an interactive operation of the interactive terminal and determine the preset value according to the interactive operation. As described above, the value of the preset value can control the bypass device 200 to cope with the failure of the first power supply 104, the preset value can be preset before the failure of the first power supply 104 (for example, when the bypass device 200 leaves the factory or when the bypass device 200 is installed in the network optical interface module 100), and after the failure of the first power supply 104, the interactive terminal can input the interactive operation to the controller 207, and the interactive operation can set or change the value of the preset value in the controller 207, and the controller 207 can perform corresponding control according to the new preset value. For example, if the preset value is set to be 1 by the interactive terminal, the controller 207 controls the bypass device 200 to start the non-bypass mode, that is, controls the second power source 205 to supply power to the optical switch 203; or the value of the preset value set by the interactive terminal is 0, the controller 207 controls the bypass device 200 to start the bypass mode, that is, controls the optical links to be established between different external interfaces 201; or the value of the preset value is changed from 0 to 1 through the interactive terminal, the controller 207 controls the bypass device 200 to be switched from the bypass mode to the non-bypass mode, that is, the optical links between different external interfaces 201 are controlled to be cut off, and meanwhile, the second power source 205 is controlled to supply power to the optical switch 203; or the value of the preset value is changed from 1 to 0 through the interactive terminal, the controller 207 controls the bypass device 200 to switch from the non-bypass mode to the bypass mode, that is, controls the second power source 205 to stop supplying power to the optical switch 203, and simultaneously controls the optical links to be established between different external interfaces 201.

According to the same inventive concept, the present disclosure also provides a network optical interface module 100 comprising any one of the above-mentioned bypass devices 200.
