Description
Technical field
The present invention relates to the computer network transmission technology, specifically refer to a kind of USB interface optical transceiver.
Background technology
In the communication technology, the type of communication channel has two classes: broadcast communication channel and point to point link channel.In broadcast communication channel, physical communication channels of a plurality of nodes sharing, a node broadcasts information, other nodes can both receive this broadcast message.And in the point to point link channel, a communication channel can only connect a pair of node, if do not have direct-connected circuit between two nodes, they can only transfer by intermediate node so.Obviously, network will be finished data transfer task by communication channel, so the transmission technology that adopts of network also only may have two classes, i.e. broadcast mode and point to point system.
In the point-to-point transmission means, the computer usb signal is subject to the restriction of short distance cable transmission, can't so that USB2.0/USB1.1 can be on cable easily prolongs, dwindled usb bus various device range of application be connected distance, so that the connection of USB device, issue and shared can't the realization, just USB hard disk, USB flash disk, serial port data acquisition or control appliance etc. can not be accessed in local computer host computer system or the control system based on usb bus, limit to transmission and the diffusion of information.
Summary of the invention
The present invention solves the problems such as the usb bus range of application is little by a kind of USB interface optical transceiver is set, and reaches the purpose of long-distance transmissions usb signal.
Purpose of the present invention reaches by the following technical programs:
The present invention includes transmitter and receiver, the transmitter of transmitter is connected by optical fiber with the receiver of receiver, described transmitter comprises a plurality of elastification grooves position, frame and controller, be provided with cavity in the frame, controller places in the cavity, described elastification groove position is arranged on the frame, and the receiver of described receiver is provided with a plurality of USB interface.The USB device of front end links to each other with the controller of transmitter by elastification groove position, and reflector transmits usb signal at optical fiber; The receiver of receiver receives usb signal, by the USB interface on the receiver, usb signal is outputed on the USB device of terminal, having broken through usb signal can only be with the restriction of short distance cable transmission, so that USB device can easily prolong on optical fiber, extension based on the range of application of the various device of usb bus be connected distance, so that the connection of USB device, wide area is propagated, issue and share and to become possibility is as with the USB hard disk, USB flash disk, camera, digital camera, audio frequency, keyboard and mouse, the access local computer host computer system such as serial port data acquisition or control appliance or based on the control system of usb bus.
Further, described USB interface is USB2.0 interface or USB1.1 interface.The equipment that arranges of compatible number of different types adapts to the signal transmission form of high low speed, and the scope of application is wider.
Further, be respectively arranged with video interface, E1 interface, Ethernet interface, telephony interface, RS485 data-interface and switching value interface in described a plurality of elastification grooves position.The setting of a plurality of elastification grooves position can be linked into the signal of the types such as synchronous and asynchronous data data center, video monitoring center, network switch, and can support mixed insertion and the access of the dissimilar integrated circuit boards such as optical fiber, video, voice, E1, Ethernet, phone, industrial data, to be formed on the comprehensive access platform of multiple business access, transmission on the identical platform.Further, also be provided with a plurality of elastification grooves position on the described receiver, be provided with video interface, E1 interface, Ethernet interface, telephony interface, RS485 data-interface and switching value interface on the elastification groove position, so that send to again the equipment to other after the signal long-distance transmission.
Further, as preferably, described Ethernet interface is 100M Ethernet interface or 1000M Ethernet interface.100M or the Fast Ethernet of 1000M can satisfy long short-range signal and transmit, and avoid signal serious damage to occur.
Further, also comprise the third level lightning protection device that is arranged on the elastification groove position.During normal operation, the access of third level lightning protection device does not affect the normal transmission of signal, and earth impedance should be large, and the impedance that is connected in the circuit is little; When thunder and lightning attacked communication bus, third level lightning protection device can be brought into play good voltage clamping effect; Suppressing to be no more than in the thunder and lightning attack process of the maximum through-current capacity of lightning protection device, third level lightning protection device attacks thunder and lightning has enough fast response speed, guarantees that electronic equipment is in the safe handling in many thunderstorms area, western part.
Further, as preferably, described optical fiber is multimode LC optical fiber.Multimode LC optical fiber (Guangzhou make progress Information technology Co., Ltd) adopts less concentricity error and diameter of bore high-precision ceramic lock pin, for the usb signal transmission provides extra insertion loss and return loss, avoid the damage of signal transmission performance decline and optical transceiving device.
The present invention compared with prior art, have following advantage and a beneficial effect:
1 the present invention includes transmitter and receiver, the transmitter of transmitter is connected by optical fiber with the receiver of receiver, described transmitter comprises a plurality of elastification grooves position, frame and controller, erecting has cavity, controller places in the cavity, described elastification groove position is arranged on the frame, the receiver of described receiver is provided with a plurality of USB interface, having broken through usb signal can only be with the restriction of short distance cable transmission, so that USB device can easily prolong on optical fiber, extension based on the range of application of the various device of usb bus be connected distance so that the connection of USB device, wide area is propagated, issue and the shared possibility that becomes.
2 USB interface of the present invention are USB2.0 interface or USB1.1 interface, and the equipment that arranges of compatible number of different types adapts to the signal transmission form of high low speed, and the scope of application is wider.
