Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a Passive Optical Network (PON) bus system, a Network control Terminal (OLT) serves as an originating Terminal of data transmission, and a plurality of Network terminals (ONU) serving as data transmission responding terminals can be connected to the OLT, thereby forming a simple linear bus system. Under the control of the OLT equipment, data transmission between the OLT equipment and the ONU equipment and data transmission between the two ONU equipment in the same network can be realized.
However, in actual use, a complex system may involve data transmission between two or more PON bus systems, and at this time, a new system needs to be constructed to implement data transmission between each terminal device among a plurality of PON bus system networks, and an auxiliary control computer in the system may connect each terminal device through an ethernet switch to implement a function of unified management and status monitoring on the terminal devices. Fig. 1 is a schematic structural diagram of a composite topology optical fiber network system according to an embodiment of the present invention, and as shown in fig. 1, the composite topology optical fiber network system includes: the system comprises an auxiliary control platform 1, a service subnet 3 and a plurality of control subnets 2;
the auxiliary control platform 1 comprises an Ethernet switch 5;
the service subnet 3 comprises an optical fiber bridge terminal 4;
each control subnet 2 is respectively in communication connection with the optical fiber bridge terminal 4; used for finishing the communication among each control subnet 2 through the terminal 4 of the optical fiber bridge;
each control subnet 2 is in communication connection with the ethernet switch 5, and is used for completing communication between each control subnet 2 and the auxiliary control platform 1 through the ethernet switch 5;
the auxiliary control platform 1 is used for monitoring and managing the communication status and the device status of each of the control subnets 2, and for monitoring and managing the communication status and the device status of the service subnets 3.
It should be noted that, in the solution provided in the embodiment of the present invention, the number of the control subnets 2 is multiple, and for convenience of illustration, the number of the control subnets 2 is drawn as 2 in fig. 1.
In the composite topology optical fiber network system provided by the embodiment of the utility model, each control subnet 2 (namely, PON bus system) is respectively in communication connection with the optical fiber bridge terminal 4 of a service subnet; the optical network bridge terminal 4 is used for completing communication among the control subnets;
each control subnet 2 is in communication connection with the ethernet switch 5, and is used for completing communication between each control subnet 2 and the auxiliary control platform 1 through the ethernet switch 5; thus, the communication between the control subnets 2 can be completed through the optical fiber bridge terminal 4. The auxiliary control platform 1 can monitor and manage the communication status and the device status of the respective control subnets 2 and the communication status and the device status of the traffic subnets 3. By the scheme, data transmission between two or more PON bus systems is completed.
The Ethernet switch is a switch for transmitting data based on Ethernet, and the Ethernet adopts a local area network of a shared bus type transmission medium mode. The ethernet switch is configured such that each port is directly connected to the host and typically operates in full duplex mode. The switch can simultaneously connect a plurality of pairs of ports, so that each pair of mutually communicated hosts can transmit data without conflict like exclusive communication media. A bridge, also called a bridge, is a store/forward device that connects two LANs, and can divide a large LAN into multiple segments, or interconnect more than two LANs into a logical LAN, so that all users on the LAN can access the server. The optical fiber bridge terminal is a bridge for data transmission by using optical fibers.
Furthermore, in the PON bus system, devices are linearly connected, the structure is relatively simple, only one device can be in a communication state at the same time, and other devices all wait, which greatly reduces the working efficiency of each device. The actually used system structure is complex, a plurality of PON bus systems can work simultaneously, and as only one OLT device can be arranged in one PON system network, and data transmission between the OLT device and the ONU device and data transmission between two ONU devices in the same network can be realized under the control of the OLT device, the data transmission between the PON bus systems is limited. In the PON bus system, the devices are independent from each other, and unified management and status monitoring of the devices cannot be achieved. In the solution provided in the embodiment of the present invention, specifically, the auxiliary control platform 1 further includes: an auxiliary control device; the auxiliary control device is connected with the Ethernet switch 5 in a communication way and is used for monitoring and managing the communication state and the device state of each control subnet 2 through the Ethernet switch 5; the communication between the control subnets 2 can be completed through the optical fiber bridge terminal 4.
Wherein the auxiliary control device may be, but is not limited to, an auxiliary control computer 8.
So configured, the auxiliary control computer 8 can implement management of the terminal device and monitoring of the data transmission state through the ethernet switch 5. In the scheme provided by the embodiment of the utility model, the auxiliary control computer executes some simple monitoring and management operations, and the operations only belong to the functions of the computer and do not relate to program improvement. In a practical arrangement, the auxiliary control device may be another controller with human-machine interaction functionality.
Specifically, the control subnet 2 includes: a network terminal 7 and a network controller 6;
the network terminal 7 is in communication connection with other network terminals 7 and network controllers 6 which control the subnet 2 through the optical fiber bridge terminal 4;
the network controller 6 is connected to other network terminals 7 controlling the subnet 2 and the network controller 6 through the optical fiber bridge terminal 4.
The network terminal 7 and the network controller 6 of the control sub-network 2 are respectively connected with the Ethernet switch 5 in a communication way.
To sum up, the composite topology optical fiber network system provided by the embodiment of the present invention can implement data transmission of each device between different PON bus systems, and can implement configuration and state monitoring of all devices in the composite topology optical fiber network. Any network terminal 7 controlling the subnet 2 can be connected with the network terminals 7 and the network controller 6 of other controlling subnets 2 in a communication way; any one of the network controllers 6 controlling the subnets 2 may be communicatively connected to the network terminals 7 and network controllers 6 of the other controlling subnets 2.
Further, the service subnet 3 further includes: and the network terminal 7 is in communication connection with the optical fiber bridge terminal 4.
The ethernet switch 5 is communicatively connected to the service subnets 3 and the respective control subnets 2 via six types of network lines 10.
The optical fiber bridge terminal 4 is in communication connection with each control subnet 2 through a single-film optical fiber 9.
The network terminals 7 of the service subnetwork 3 are connected to the ethernet switch 5 via six types of network lines 10.
It should be noted that the six types of network cables 10 refer to six types of cables, that is, cables conforming to the CAT-6 standard. The six types of network lines 10 can be used for voice, Integrated Services Digital Network (ISDN), ATM155Mbps and 622Mbps, 100Mbps tpddi, fast ethernet and gigabit ethernet; compared with the five types and the ultra-five types, the transmission device has the characteristics of long transmission distance, small transmission loss, wear resistance, pressure resistance and the like.
The diameter of a fiber core of the single mode fiber (singlemode fiber) is only 8-10 mu m, and light rays propagate in a linear shape along the direction of the central axis of the fiber core. Since such a fiber can only transmit one mode (degeneracy of two polarization states), it is called a single-mode fiber, and its signal distortion is small. The dispersion between modes is very small, and the optical fiber is suitable for remote communication, but material dispersion and waveguide dispersion exist, so that the single-mode optical fiber has higher requirements on the spectral width and stability of a light source, namely the spectral width is narrow and the stability is good. At a wavelength of 1.31 μm, the material dispersion and waveguide dispersion of a single mode fiber are positive one and negative one, and are also exactly equal in magnitude. Therefore, the 1.31 μm wavelength region is a very ideal working window for optical fiber communication. Compared with multimode fiber, the single-mode fiber can support longer transmission distance, and in 100Mbps Ethernet and up to 1G gigabit network, the single-mode fiber can support transmission distance exceeding 5000 m.
Further, in practical applications, the number of the control subnets 2 is not fixed, and when the number of the control subnets 2 is large, the interface of the optical network bridge terminal 4 may be insufficient, and for this situation, the optical network bridge terminal 4 in the embodiment of the present invention is provided with a plurality of expansion interfaces. This arrangement allows the fibre-bridge terminal 4 to accommodate a larger number of control subnets 2.
In combination with the above preferred embodiments, the composite topology optical fiber network system provided in the embodiment of the present invention includes: the system comprises an auxiliary control platform 1, a service subnet 3 and a plurality of control subnets 2; the auxiliary control platform 1 comprises an Ethernet switch 5 and an auxiliary control computer 8; the service subnet 3 comprises an optical fiber bridge terminal 4 and a network terminal 7; each of the control subnets 2 includes: a network terminal 7 and a network controller 6; the network terminal 7 and the network controller 6 of each control subnet 2 are respectively in communication connection with the optical fiber bridge terminal 4; for completing the communication between the network terminal 7 and the network controller 6 of each control sub-network 2 via said fibre-optic bridge terminal 4.
The network terminal 7 and the network controller 6 of each control subnet 2 are respectively in communication connection with the ethernet switch 5, and are used for completing the communication between the network terminal 7 and the network controller 6 of each control subnet 2 and the auxiliary control computer 8 through the ethernet switch 5; the auxiliary control computer 8 is also connected in communication with the optical fiber bridge terminal 4 and the network terminal 7 of the service network subnet through the ethernet switch 5. The auxiliary control computer 8 thus monitors and manages the communication status and the device status of the respective control subnets 2 and the communication status and the device status of the traffic subnets 3 via the ethernet switch 5. Through the composite topology optical fiber network system, data transmission of each device among different PON bus systems is realized, and configuration and state monitoring of all devices in the composite topology optical fiber network can be realized.
