Abstract
The utility model relates to an optical relay for whole-optical network 650 nm information transmission systems, which relates to the user terminal equipment of an optical network and is composed of a power switching circuit, power source processing circuits for optical fibre modules, an optical fibre module IP1 and an optical fibre module IP2, wherein the power switching circuit is formed by changing a 220V AC voltage to a + 5V DC voltage circuit. The power source processing circuits for the optical fibre module are connected with the output circuit of the +5V DC voltage. The optical fibre module IP1 and the optical fibre module IP2 are respectively connected with the output terminals of the corresponding power source processing circuit for optical fibre modules. The input and output terminals of the optical fibre module IP1 are respectively connected with the output and input terminals of the optical fibre module IP2. When a 1550 nm silicon fiber signal, a 1310 nm silicon fiber signal and an 850 nm silicon fiber signal are respectively converted to a 650 nm plastic fiber signal, the plastic optical fiber network carries out connection with the silicon fiber network on a main road. Terminal-users with transmission distances which are longer than 50 meters can cause light obtain relay and amplification to cause the transmission distances to be farther and the plastic optical fiber system is caused to be communicated with a public information network for carrying out optical communication intercommunication in the global and whole-optical network.
Description
Technical field
The utility model relates to a kind of network equipment, especially a kind of subscriber terminal equipment of optical-fiber network, " last kilometer " subscriber terminal equipment that just is commonly called as usually.
Background technology
The silica fiber network information on the existing backbone must be through light/electricity, electricity/light conversion when access user terminal, and this changing turns over journey and not only influence transmission speed, and causes signal attenuation, information distortion, is subject to external interference, and the information that also is prone to is stolen.
In order to change the above-mentioned defective in the existing information transmission, a kind of all-optical network just under study for action, all-optical network becomes the first-selection of (ultrahigh speed) broadband network at a high speed of future generation with its good transparency, wavelength routing characteristic, compatibility and extensibility.In order to reach at user terminal, be that last kilometer is still with optical transmission information, must convert existing 1550nm, 1310nm, 850nm silica fiber signal to 650nm plastic fiber signal respectively, could further be transformed into user terminal then, because the different positions of user terminal, signal produces decay in transmission course, carries out the 650nm optical relay because of the oversize needs of distance in plastic fiber system integration all-optical network, do not have optical relay, just can not finish the UNICOM of full light network diagram.
The utility model content
The utility model purpose be exactly for transmission range more than 50 meters the terminal use optical repeater of all optical network 650nm information transmission system of optical relay is provided.
The utility model is mainly by power-switching circuit, optic module power supply processing circuit, optic module IP
1With optic module IP
2Form, power-switching circuit converts to+the 5V dc voltage circuit for the 220V alternating voltage, the optic module power supply processing circuit is connected+the 5V dc voltage output circuit on, optic module IP

1Input (RXI1+/RXI1-) and output (TXO1+/TXO1-) respectively with optic module IP
2Output (TXO2+/TXO2-) be connected with input (RXI2+/RXI2-).
After 1550nm, 1310nm, 850nm silica fiber conversion of signals become 650nm plastic fiber signal, plastic optical fiber network is connected with silica fiber network on the major trunk roads, transmission range more than 50 meters the terminal use make light obtain relaying by the utility model, amplify so that it transmits more fartherly, make plastic fiber system and the common information net can intercommunication, carry out the optical communication intercommunication of full process and full network.Because repeater directly uses 220V power supply power supply, the 220V alternating voltage must be converted to+the 5V direct voltage can use, be finished by an integrated power supply module, to supply with whole repeater.Repeater is exactly a kind of network access device that amplifies the analog or digital signal.For plastic fiber, because its loss is bigger, its transmission range is nearer relatively, so repeater is extremely important for the coverage of effective prolongation plastic optical fiber network.
In the optic module power supply processing circuit in the utility model, each road VccT and VccR are connect inductance and filter capacitor respectively, purpose is to strengthen the antijamming capability of repeater.
The utility model connects the power supply indicator circuit in also on+5V dc voltage output circuit, be made up of light-emitting diode of a resistance series connection.After system powered on, this LED was luminous, indication power module operate as normal.
