Description
Technical field
The present invention relates to a kind of optical module, more particularly to a kind of fibre-optical splice.
Background technology
The development of hardware and internetworking is maked rapid progress now, and guiding people are more and more big to the demand of network bandwidth, net
Network communication with fast lifting bandwidth, must also provide the service of more and more information transmission.Servo is connected in servo central
The wire communication module of host to save outside energy consumption, and is into one except previous metallic circuit is changed to fibre circuit
Step reduces the volume of communication module, has started single-channel fibre circuit connector progressively, by multi channel fibre circuit connector
Substitution.Such multichannel fibre circuit is the pattern for carrying out multiple optical fiber parallel transmissions, using for multi-channel optical fibre parallel transmission
Plug connector, as light source, optical fiber, receive photoreceptor between transmit light signal guide-lighting physical components.This multichannel optical fiber
Connector can be divided into the internal connector unit for being equipped with multiple optical fiber, and the lens unit with guiding light trend passes through accurate guide post
After two units, as possesses interconnection connector pluggable, easy to use.In order to increase the running bandwidth of each channel, light
Signal must maintain more stable operating energy, make foregoing multichannel fibre-optical splice, built-in to provide and stablize the running of light signal
The function of energy.
However, to stablize the operating energy of light signal, there need to be good working environment and possess the light of stabilized illumination efficiency
Source, but under the requirement of long time running, it is difficult to meet what foregoing high frequency operated using the light source power supply system for opening circuit control
It is required that, it is necessary to import closed loop control system, the variation increased or reduced by direct monitoring light signal energy feeds back to light source
Drive electric power unit, with decrease or increase driving light source electric energy, maintain the light signal energy of system operation in stable state.
So in foregoing fibre-optical splice module, detection photoreceptor need to be increased, to detect the variation of light source luminous energy, and need to build
The optical texture of light can be separated on opticpath, the condition of original transmission light signal is not destroyed or disturb in the optical texture
Under, the light energy of fixed proportion is isolated from the light signal of communication, and guide to detection photoreceptor and monitor, this is to have
The job requirement of the optical module in monitoring light splitting path.
Itd is proposed one of the prior art such as US6,888,988B2, US8,283,678B2, US8,457,457B2 Patent Case
The optical module of formula component.The function of the optical module is the first light for sending light source, with the incident light of the first light path
After learning component, by an optical reflection face built in the optical module, reflexed to and the first light path according to optical total-reflection principle
On the direction of 90 degree of angle (being not limited to 90 degree), after which moves ahead and leave the optical module, to be placed in first
Fiber end face on light path is received, and completes the transmission of the first light.The prior art and in foregoing first light path, in group
Part material internal establishes specific structure (generally groove structure), can will pass through the part luminous energy of the incident light of the specific structure
Amount, deviation or reflects the second light to the second light path, which advances along the second light path, in leaving the optics
It after component, is received by the detection photoreceptor that is placed on the second light path, the second light can measure this detection photoreceptor at once
Amount, since the energy of the second light and the energy of the first light maintain constant ratio, the luminous energy of detection photoreceptor detecting gained
Amount is directly proportional to light signal energy, according to foregoing loop circuit pattern, can control the stabilization of light signal energy.
With respect to the design of multi-piece type optical module, the advantages of foregoing single type optical module, is minimum in package count, is not required to group
Vertical cost.Although the structure of single type optical module is more complicated, manufacture difficulty is higher, and the manufacture that need to only control a component is public
Difference；Multi-piece type optical module is composed of multiple components, and the structure of each component is relatively simple, and manufacture difficulty is relatively low, but right
The combinatorial surface of component especially controls manufacturing tolerance, makes combine component that can still meet the rigorous of control light.Single type optics
The shortcomings that component, is when light signal energy is too strong, and light emitting source is not suitable for downgrading the special status of luminous working condition, needs reality
The methods of being about to component plated film or sticking on an optical filter or the material using reduction penetrance, to reduce too strong light signal
The advantages of energy, these methods can all increase establishment of component cost, can not show single type optical module.
Another prior art, such as US8, the two-piece type optical module that 503,838B2 Patent Cases are proposed are similary to have prison
The structure design of light source is controlled, if run into light signal energy to be turned down, wherein a piece of assembly surface, which is increased, reduces penetrance
Plated film.Such two-piece type optical module design compares foregoing single type optical module design, light guide structure is separated
To two components, various components making is relatively easy to, and when plated film fails, also need to only abandon one of plated film, it appears that can drop
It is low to be lost caused by plated film is bad, however the two pieces component of above-mentioned Patent Case has lens curved surface and groove structure, even if plating
The undesirable loss of film is relatively low, makes plus the still more foregoing single type optical module of resulting cost is high.
Another prior art, such as US8, the three-member type optical module that 787,714B2 Patent Cases are proposed, it may have monitoring
The structure design of light source, feature, which is to have between lensed component body, the second component and tablet filter disc three, needs filler to go
Except the air between interface, to avoid optical total-reflection completely.When needing to reduce light signal energy, as long as replacing specific standard
Tablet filter disc improves foregoing single type optical module and two-piece type optical module plated film bad the problem of causing damages.
However this designs residual bubble inside or outside the colloid that when making, will face filling interface and is difficult to the situation avoided completely,
Once light signal runs into bubble, the energy except reducing light signal, the extra spurious rays produced by bubble interface, it is also possible to
The noise in communication is formed, influences the transmission of signal.
