Abstract
In order to combine IP data with signals of a cable television organically, the same coaxial cable is used to connect a user so that not only transmission of the signals of the cable television is not affected, but access of user bidirectional network comprehensive services is also realized and thus a problem that cost is high in overall laying of networks is solved. The utility model provides a digital EOC-device connection system based on combination of three networks. The digital EOC-device connection system based on the combination of the three networks mainly includes an ONU, an EOC head end, an EOC coaxial switch, an EOC terminal, category-V wires and coaxial cables, wherein the EOC head end, the ONU and a cable-television optical station are arranged beside a building or in a district. The category-V wires are connected with the coaxial cables respectively. The EOC terminal is arranged in a house of the user. The EOC coaxial switch is arranged between the EOC head end and the EOC terminal.
Description
Technical field
The utility model relates to cable TV and wideband data access technology, is specifically related to a kind of digital EOC equipment access system based on the integration of three networks.
Background technology
Along with the quickening of national integration of three networks process, the continuous progress of the communication technology, the business that each common carrier is carried out is also to development in pluralism.In this process, the fiber optic network access technology, as the ring in communication network nowadays, has been played the part of more and more important role in whole communication system.At present the radio and TV operator, mainly adopt the optical fiber bidirectional network access technique, in the situation that access user quantity is more, has that the cable resource utilance is low, network cost is high, fault point is many, and the high shortcoming of equipment investment cost.
The utility model content
Technical problem to be solved in the utility model is, for IP data and cable TV signal are organically combined, with same coaxial cable access user, neither affect the transmission of cable TV signal, realize that again user's bilateral network is combined and the access of business, solve the high problem of the required cost of network of comprehensively laying, a kind of digital EOC equipment access system based on the integration of three networks is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of digital EOC equipment access system based on the integration of three networks mainly comprises ONU, EOC head end, the coaxial switch of EOC, EOC terminal, 5 class line and coaxial cables; Wherein EOC head end and ONU and Cable TV Light Station are placed in the Lou Bianhuo community, use respectively 5 class lines to be connected with coaxial cable; The EOC terminal is placed in user house; Establish the coaxial switch of EOC between EOC head end and EOC terminal.
Described ONU is by optical fiber access, between ONU and EOC head end, by 5 class lines, connects, between EOC head end and the coaxial switch of EOC, all be connected by coaxial cable between the coaxial switch of EOC and EOC terminal; Be connected by 5 class lines between EOC terminal and computer in user family, and be connected by coaxial cable between EOC terminal and TV in user family.
The effect of described EOC head end is to meet the ethernet signal of 802. 3 agreements, to mix with cable TV signal, then transmits and register one's residence by a coaxial cable.
The EOC terminal is placed in user house, and its effect is that mixed signal is separated again, thereby realizes the access of user's bilateral network integrated service.
The setting of the coaxial switch of EOC, can transmit ethernet signal and limited TV signal to multi-user in building.
The digital EOC equipment access system of the utility model based on the integration of three networks, can be used for the Two-way Network transformation of cable TV, be the radio and TV operator for the user provides the important step of multi service access, this system has advantages of reliability, advance, extensibility, opening and standard, safety and manageability.This system, by the transformation of the optical-fiber network to Access Network, realizes the purpose of the integration of three networks, and reduces costs for the radio and TV operator lays network comprehensively.

In figure, 1, ONU; 2, EOC head end; 3, the coaxial switch of EOC; 4, EOC terminal; B1,5 class lines one; B2,5 class lines two; A, coaxial cable; A1, coaxial cable one; A2, coaxial cable two; A3, coaxial cable three; 51, computer; 52, TV.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, this embodiment, a kind of digital EOC equipment access system based on the integration of three networks, mainly comprise ONU, EOC head end, the coaxial switch of EOC, EOC terminal, 5 class line and coaxial cables; Wherein EOC head end and ONU and Cable TV Light Station are placed in the Lou Bianhuo community, use respectively 5 class lines to be connected with coaxial cable; The EOC terminal is placed in user house; Establish the coaxial switch of EOC between EOC head end and EOC terminal.
As shown in Figure 1, described ONU is by optical fiber access, between ONU and EOC head end, by 5 class lines one, connects, and between EOC head end and the coaxial switch of EOC, by coaxial cable one, is connected, all is connected by coaxial cable two between the coaxial switch of EOC and EOC terminal; Be connected by 5 class lines two between EOC terminal and computer in user family, and be connected by coaxial cable three between EOC terminal and TV in user family.
As shown in Figure 1, the effect of described EOC head end is to meet the ethernet signal of 802. 3 agreements, to mix with cable TV signal, then transmits and register one's residence by a coaxial cable.
As shown in Figure 1, the EOC terminal is placed in user house, and its effect is that mixed signal is separated again, thereby realizes the access of user's bilateral network integrated service.
As shown in Figure 1, the setting of the coaxial switch of EOC, can transmit ethernet signal and limited TV signal to multi-user in building.
The digital EOC equipment access system of this embodiment based on the integration of three networks, can be used for the Two-way Network transformation of cable TV, be the radio and TV operator for the user provides the important step of multi service access, this system has advantages of reliability, advance, extensibility, opening and standard, safety and manageability.This system, by the transformation of the optical-fiber network to Access Network, realizes the purpose of the integration of three networks, and reduces costs for the radio and TV operator lays network comprehensively.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or say that without improvement design of the present utility model and technical scheme are applied to other occasions, all in protection range of the present utility model.
