Description

There is the optical module in monitoring light splitting path
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, guides the need to the network bandwidth for the people Ask more and more big, network communication also must provide more and more multi information with fast lifting bandwidth The service of transmission.Connect the wire communication module of servo host in servo central, except will be with Past metallic circuit is changed to fibre circuit, is consumed outer with save energy, and logical for reducing further The volume of news module, has started to progressively by single-channel fibre circuit joint, by multi channel light Fine line joint replaces.Such multichannel fibre circuit is the mould carrying out multiple optical fiber parallel transmissions Formula, using the plug joint being available for multi-channel optical fibre parallel transmission, as light source, optical fiber, reception The guide-lighting physical components of light signal are transmitted between photoreceptorss.This multichannel fibre-optical splice, can be divided into Inside is provided with the connector unit of multiple optical fiber, the lens unit with guiding light trend, passes through After accurate guide pillar combines two units, as possesses pluggable, convenient use interconnection joint. In order to increase the running bandwidth of each channel, light signal must maintain more stable operating energy, make Aforesaid multichannel fibre-optical splice, built-in will provide the function of stablizing light signal operating energy.
However, the operating energy of light signal will be stablized, need to there is good working environment and possess steady Determine the light source of luminous efficiency, but under the requirement of long time running, using the light opening circuit controls Source power supply system, hardly possible meet the requirement of aforementioned high frequency running, need to import loop circuit control system System, the change increased or reduce by direct monitoring light signal energy, feed back to the driving of light source Supply unit, to decrease or increase the electric energy driving light source, maintains the light signal energy of system operation Amount is in steady statue.So in aforementioned fibre-optical splice module, detection photoreceptorss need to be increased, with The variation of detecting light source luminous energy, and need to build to separate the optical texture of light in light On path, under conditions of this optical texture does not destroy or disturbs original transmission light signal, certainly logical Isolate the light energy of fixed proportion in the light signal of news, and guide and supervise to detection photoreceptorss Control, this as has the job requirement of the optical module in monitoring light splitting path.
Such as US6,888,988B2, US8,283,678B2, US8,457,457B2 are special for prior art The optical module of the single type assembly that sharp case is proposed.The function of this optical module is to send out light source The first light going out, after first light path this optical module of incidence, in this optical module Put an optical reflection face, reflex to and the first light path angle 90 according to optical total-reflection principle On the direction of degree (being not limited to 90 degree), after this first light moves ahead and leaves this optical module, Fiber end face by being placed on the first light path is received, and completes the transmission of the first light.Existing There is technology and in aforementioned first light path, set up ad hoc structure inside assembly material (general For groove structure), can by the part light energy of the incident illumination through this ad hoc structure, deviation or Reflect the second light to the second light path, this second light is advanced along the second light path, in After leaving this optical module, received by the detection photoreceptorss being placed on the second light path, this detects The energy measurement of inspection photoreceptorss the second light at once, due to energy and first light of the second light Energy maintain constant ratio, light energy and the light signal energy of gained detected by this detection photoreceptors It is directly proportional, just can control stablizing of light signal energy according to aforementioned loop circuit pattern.
The design of relative multi-piece type optical module, the advantage of aforementioned single type optical module is in assembly Number is minimum, is not required to organize vertical cost.Although the structure of single type optical module is more complicated, it is difficult to manufacture Degree is higher, but only need to control the manufacturing tolerance of an assembly;Multi-piece type optical module is by multiple groups Part combines, and the structure of each assembly is relatively simple, and manufacture difficulty is relatively low, but will be to assembly Combinatorial surface especially controls manufacturing tolerance, so that combine component still can be met and controls the precision of light to want Ask.The shortcoming of single type optical module, is when light signal energy is too strong, and luminous source is not suitable for Downgrade luminous working condition special status when, need to carry out assembly plated film, or stick on a filter Mating plate, or using methods such as the materials reducing penetrance, to reduce too strong light signal energy, These methods all can increase establishment of component cost it is impossible to the advantage that represents single type optical module.
Another prior art, such as US8, the two-piece type optics that 503,838B2 Patent Cases are proposed Assembly, equally has the structure design of monitoring light source, if running into when will turn down light signal energy, Wherein a piece of assembly surface is increased the plated film reducing penetrance.Such two-piece type optics Assembly designs, and compares aforementioned single type optical module design, by light guide structure separately to two groups Part, each establishment of component is relatively easy to, and when plated film failure, also only need to abandon the one of plated film Part is it appears that the loss leading to because plated film is bad can be reduced, but the two pieces assembly of above-mentioned Patent Case All there are lens curved surface and groove structure, even if the bad loss of plated film is relatively low, make the one-tenth adding up Originally still more aforementioned single type optical module is high.
Another prior art, such as US8, the three-member type optics that 787,714B2 Patent Cases are proposed Assembly, it may have the structure design of monitoring light source, feature be to have lensed component body, Filler is needed to remove the air between interface, to keep away completely between the second assembly and flat board filter disc three Exempt from optical total-reflection.When needing to reduce light signal energy, as long as changing the flat board of specific standard Filter disc, improves that aforementioned single type optical module is bad with two-piece type optical module plated film to be made Become the problem of loss.But this design is when making, by internal for the colloid facing filling interface or Outside residual bubble is difficult to the situation avoiding completely, once light signal runs into bubble, except reducing The energy of light signal, is produced unnecessary spurious rays it is also possible to form communication in bubble interface In noise, impact signal transmission.
