Description
Technical field
The present invention relates to a kind of network configuration of computer-internal, especially relate to the simple short-distance optical fiber network of a kind of structure.
Background technology
Optical fiber application is in a computer network more and more extensive.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, lightweight etc.
Computer-internal transmission is at present general or based on the signal of telecommunication, and along with transmitted data amount increasing, use optical fiber and optical signal communication will be Computer development trend between each parts.
Existing fibre concentrator generally all adopts and first light signal is converted into the signal of telecommunication, and by being converted into the mode of light signal after distributing again, cause optical network structure complicated, many places conversion can bring interference and error code, and reduce transmission speed, cost is higher.
State Intellectual Property Office of the People's Republic of China discloses on May 7th, 2003 patent documentation that publication number is CN1415988A, and title is hub of multimode optical fiber in reflection type.It utilizes mirror-reflection principle, by the light signal of different mode transmitted in multimode fiber, utilize the control of angle of reflection, by 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 that light signal is separated is conditional, the signal of each root optical fiber all can not be delivered in other optical fiber and go.
Summary of the invention
The optical network structure that the present invention mainly solves existing for prior art is complicated, Signal separator needs multiple conversions or can only carry out the technical problem of the separation of limited scheme, provides that a kind of structure is simple, cost is low, just can separated light signal and the unconfined short-distance optical fiber network of separation scheme without the need to carrying out opto-electronic conversion and electro-optic conversion.
The present invention is directed to that above-mentioned technical problem mainly solved by following technical proposals: a kind of short-distance optical fiber network, comprise diffuse reflection ball and optical fiber, optical fiber one end connects photoelectric/electro-optical conversion module, diffuse reflection ball inner hollow, diffuse reflection ball wall has the through hole matched with optical fiber size, optical fiber inserts through hole, and diffuse reflection ball inwall scribbles the whitewash layer of diffuse, through hole is greater than one.The present invention is applied to the communication between each parts of computer-internal, and photoelectric/electro-optical conversion module is connected with each parts, can be spread out of needing the signal of telecommunication transmitted to be converted to light signal by optical fiber.Light signal reaches after in diffuse reflection ball through optical fiber, through the diffuse reflection of whitewash layer, all can provide light signal for other each root optical fiber.Because computer-internal transmission range is very short, even also can not cause cannot the problem of identification so light signal weakens through diffuse reflection.
As preferably, the reflection wavelength of whitewash layer is the wavelength of the light wave transmitted in optical fiber.Can ensure that light wave obtains best diffuse effect like this.
As preferably, the present invention also comprises a light source, and it is inner that light source is arranged on diffuse reflection ball.Light signal can be sent directly to other optical fiber by light source.
As preferably, light source is LED.Computer-internal transmission demand does not have external network so high, just can meet the demands so carry out transmission of signal with the flicker of LED lamplight.
As preferably, photoelectric/electro-optical conversion module comprises photodiode and LED.Light signal can be converted to the signal of telecommunication by photodiode, carries out to the signal of telecommunication information that demodulation can restore transmission.LED can convert electrical signals to light signal, passes to diffuse reflection ball by optical fiber.
The substantial effect that the present invention brings is, structure is simple, and cost is low, just can reach the object of separated light signal to other multifibers without the need to opto-electronic conversion and electro-optic conversion.
