Abstract
The utility model discloses a short-distance optical fiber network. The short-distance optical fiber network has a simple structure and is cost-saving, and is provided with an unrestricted separating scheme in which light signals can be separated without being subjected to photoelectric conversion and electro-optic conversion. The short-distance optical fiber network comprises a diffuse reflection ball and optical fibers, wherein, one ends of the optical fibers are connected with the photoelectric/electro-optic conversion module; more than one through holes matched with the size of the optical fiber is formed on the wall of the hollow diffuse reflection ball; the optical fibers are inserted into the through holes; and a diffuse reflection white coating is coated on the inner wall of the diffuse reflection ball. The short-distance optical fiber network is used for realizing communication among the internal parts of a computer; the photoelectric/electro-optic conversion module is connected with all parts so as to convert the electrical signals required to be transmitted into the light signals and then transmit the light signals out through the optical fibers; and the light signals, which are subjected to the diffuse reflection of the white coating after reaching the diffuse reflection ball through the optical fibers, can provide light signals for every other optical fiber. Therefore, the short-distance optical fiber network is suitable for realizing the signal transmission among the parts of the computer.
Description
Technical field
The utility model relates to a kind of network configuration of computer-internal, especially relates to a kind of short distance fiber optic network simple in structure.
Background technology
The application of optical fiber in computer network more and more widely.The advantage of Optical Fiber Transmission comprises: 1, low-loss and high wideband; 2, size is little and bending radius is little; 3, non-conductive, non-radiating, do not respond to; 4, in light weight etc.
The computer-internal transmission is general at present to be main with the signal of telecommunication still, and along with data amount transmitted is increasing, using optical fiber and light signal communication between each parts will be the computer development trend.
Existing fibre concentrator generally all adopts and earlier light signal is converted into the signal of telecommunication, through being converted into the mode of light signal after distributing again, causes optical network structure complicated, and the many places conversion can bring to be disturbed and error code, reduces transmission speed, and cost is higher.
It is the patent documentation of CN1415988A that State Intellectual Property Office of the People's Republic of China discloses publication number on May 7th, 2003, and title is a hub of multimode optical fiber in reflection type.It utilizes the direct reflection principle; With the light signal of the different mode that is transmitted in the multimode fiber, utilize the control of angle of reflection, with the light signal of reflection; Be separated in each optical fiber parallel and arranged side by side, the spacing of each optical fiber must be adjusted by the size of the angle of reflection of mirror surface and optical fiber.The weak point of this scheme is that the scheme of separate optical signals is conditional, can not the signal of each root optical fiber all be delivered in other optical fiber to go.
Summary of the invention
The utility model mainly is to solve existing in prior technology optical network structure complicacy; Signal Separation needs multiple conversions or the technical problem that can only carry out the separation of limited scheme, provide a kind of simple in structure, cost is low, need not to carry out opto-electronic conversion and the electric light conversion just can separated light signal and the unconfined short distance fiber optic network of separation scheme.
The utility model mainly is able to solve through following technical proposals to above-mentioned technical problem: a kind of short distance fiber optic network; Comprise diffuse reflection ball and optical fiber, optical fiber one end connects photoelectricity/electrooptic conversion module, diffuse reflection ball inner hollow; Have the through hole that matches with the optical fiber size on the diffuse reflection ball wall; Optical fiber inserts through hole, scribbles the whitewash layer of diffuse on the diffuse reflection ball inwall, and through hole is greater than one.The utility model is applied to the communication between each parts of computer-internal, and photoelectricity/electrooptic conversion module is connected with each parts, can convert the needs electrical signal delivered into light signal and spread out of through optical fiber.After light signal reached in the diffuse reflection ball through optical fiber, the diffuse reflection through the whitewash layer can all provide light signal for other each root optical fiber.Because the computer-internal transmission range is very short, so even light signal weaken through diffuse reflection can not cause yet can't identification problem.
As preferably, the reflection wavelength of whitewash layer is the wavelength of the light wave that transmits in the optical fiber.Can guarantee that like this light wave obtains best diffuse effect.
As preferably, the utility model also comprises a light source, and it is inner that light source is arranged on the diffuse reflection ball.Can directly send light signal through light source to other optical fiber.
As preferably, light source is LED.The computer-internal transmission demand does not have external network so high, just can meet the demands so transmit signal with the flicker of LED light.
As preferably, photoelectricity/electrooptic conversion module comprises photodiode and LED.Photodiode can convert light signal into the signal of telecommunication, the signal of telecommunication is carried out demodulation can restore information transmitted.LED can be a light signal with electrical signal conversion, passes to the diffuse reflection ball through optical fiber.
The beneficial effect that the utility model brings is that simple in structure, cost is low, need not the conversion of opto-electronic conversion and electric light and just can reach the purpose of separated light signal to other multifibers.
