Abstract
The utility model discloses a repeater on the basis of a physical layer of a gigabit Ethernet. The repeater comprises a network interface of a receiving end, a network interface of a transmitting end, network transformers and gigabit Ethernet physical layer integrated chips. Each network transformer is positioned between the corresponding gigabit Ethernet physical layer integrated chip and the corresponding network interface, the gigabit Ethernet physical layer integrated chip of the receiving end receives data meeting the requirement of a gigabit Ethernet format via the corresponding network transformer and the corresponding network interface and transmits the data to the gigabit Ethernet physical layer integrated chip of the transmitting end via a parallel data interface or a serial data interface, and the gigabit Ethernet physical layer integrated chip of the transmitting end forwards the data via the network transformer of the transmitting end and the network interface of the transmitting end. The repeater has the advantages that attenuated data can be further recovered, and the recovered data can be completely forwarded; and the repeater can be applied to a twisted-pair transmission system of the gigabit Ethernet, can also be used for an existing twisted-pair distribution network, and is stable in transmission and extremely low in cost.
Description
Technical field
The utility model relates to technical field of security and protection, is specifically related to a kind of repeater based on the gigabit Ethernet physical layer.
Background technology
Repeater (RP repeater) is a kind of device of interconnection network circuit, is usually used in the two-way converting work of physical signalling between two network nodes.Repeater is the simplest InterWorking Equipment that is used for prolonging network distance under the LAN environment, repeater has the function of amplifying regeneration to signal on the line, mainly finish the function of physical layer, be responsible for step-by-step transmission of information on the physical layer of two nodes, the copying of settling signal, adjustment and enlarging function prolong the length of network with this.Owing to there is loss, the signal power of transmission can decay gradually on the line, will cause distorted signals when decaying to a certain degree, therefore can cause receiving mistake.Repeater designs for addressing this problem.It finishes the connection of physical circuit, and the signal of decaying is amplified, and keeps identical with former data.Generally speaking, what the two ends of repeater connected is identical media, but the repeater that has also can be finished the transit working of different media.The use of repeater is unlimited theoretically, and therefore network also can infinitely prolong.In fact this is impossible because in the network standard all the delay scope to signal made concrete regulation, repeater can only effectively be worked in this prescribed limit, otherwise can cause network failure.
Device and the shortcoming thereof of prolongation Internet Transmission distance commonly used.
1. in the market only based on the repeater of the Double-strand transmission of 100 m ethernet or 10 mbit ethernets, gigabit Ethernet has begun a large amount of uses, but does not have corresponding repeater.
2. in the market gigabit Ethernet optical transceiver can prolong the gigabit Ethernet data transmission distance equally, but he must have fiber optic network, and the optical transceiver cost is higher.
3. in the market gigabit ethernet switch or router, can realize all functions of this device, but because they have used the above agreement of gigabit Ethernet physical layer, cost is very high, and the risk that exists of the above agreement of ethernet physical layer makes transmission unstable.
The utility model content
For above-mentioned prior art, the technical problems to be solved in the utility model is: use gigabit ethernet switch, router or gigabit Ethernet optical transceiver cost higher; And use existing twisted-pair feeder routing network, in the gigabit Ethernet data transmission system of hundreds of rice, signal power can decay gradually, will cause distorted signals when decaying to a certain degree, therefore can cause the receive data mistake.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of repeater based on the gigabit Ethernet physical layer, the network interface, network transformer, the gigabit Ethernet physical layer integrated chip that comprise receiving terminal and transmitting terminal, and the electric supply installation of two gigabit Ethernet physical layer integrated chips, it is characterized in that described network transformer is between gigabit Ethernet physical layer integrated chip and network interface; Described receiving terminal gigabit Ethernet physical layer integrated chip receives the data that meet the gigabit Ethernet form by network transformer, network interface, by parallel data grabbing card or serial data interface, send to transmitting terminal gigabit Ethernet physical layer integrated chip, transmitting terminal gigabit Ethernet physical layer integrated chip is gone out data retransmission by transmitting terminal network transformer, network interface again.
Say that further two network interfaces of described reception and transmitting terminal, two network transformers, two gigabit Ethernet physical layer integrated chips and electric supply installation are integrated on the circuit board.
Say that further described network interface is the RJ-45 network interface.
Say that further described receiving terminal and transmitting terminal exchange and be transmitting terminal and receiving terminal.
The beneficial effects of the utility model show:
One, the data that decayed is carried out a secondary data and recover, the data of recovering are forwarded fully.
Two, can apply in the twisted pair transmission system of gigabit Ethernet; Also can use existing twisted-pair feeder routing network, and transmission is stable, cost is very low.
Description of drawings
Fig. 1 is the theory diagram of utility model.
Embodiment
The utility model will be further described below in conjunction with the drawings and the specific embodiments.
A kind of repeater based on the gigabit Ethernet physical layer, comprise two RJ-45 network interfaces, two network transformers, two gigabit Ethernet physical layer integrated chips and electric supply installation, connect a network transformer between described gigabit Ethernet physical layer integrated chip and the RJ-45 network interface; Electric supply installation links to each other with the mbit ethernet physical layer integrated chip of transmitting terminal, the gigabit Ethernet physical layer integrated chip of receiving terminal respectively.
In conjunction with shown in Figure 1, the gigabit Ethernet physical layer integrated chip of transmitting terminal receives the data that meet the gigabit Ethernet form by network transformer, RJ-45 network interface, by parallel data grabbing card or serial data interface, send to the gigabit Ethernet physical layer integrated chip of receiving terminal, the gigabit Ethernet physical layer integrated chip of receiving terminal is gone out data retransmission by network transformer, RJ-45 network interface again; Equally, the gigabit Ethernet physical layer integrated chip of receiving terminal receives the data that meet the gigabit Ethernet form by network transformer, RJ-45 network interface, by parallel data grabbing card or serial data interface, send to the gigabit Ethernet physical layer integrated chip of transmitting terminal, the gigabit Ethernet physical layer integrated chip of transmitting terminal is gone out data retransmission by network transformer, RJ-45 network interface again.Thereby can realize meeting the transmitted in both directions of the data of gigabit Ethernet form.
The utility model amplifies the data-signal that meets the gigabit Ethernet form, transmits and originally identical data, thereby has prolonged the distance of gigabit Ethernet transfer of data.
