Background technology
Along with the construction of short distance and jumbo data center, the update of supercomputer, router and switch has become not inundant trend, and people increase day by day to the demand of bandwidth and port density reinforcement.The interconnection of 850nm VCSEL multichannel light based on multimode optical fiber, have low in energy consumption, cost is low, lightweight, integrated level advantages of higher, by high volume applications, the demand of following this generic module product can be increasing.Go out the operation of luminous power, stabilizing equipment and the module of fixing a breakdown is in time loved by users deeply with monitoring function backlight, real-time report.But research and development high performance-cost ratio be with monitoring module backlight, become the key cards that industry dominates the market.
But VCSEL is surface-emitting laser, do not have like edge-emitting laser itself backlight, need designer in the past light separate a part, cause MPD.So 850 VCSEL single channel devices are mainly the light splitting pieces that adds an inclination before scioptics, emergent light antireflection part is formed to back facet current to MPD.But multi-channel parallel component compact, and need the problems such as crosstalk between " Lu Yulu ", therefore, the backlight design of prior art is not too applicable, can not meet the need of market comprehensively.
Summary of the invention
For solving the problems of the technologies described above, fundamental purpose of the present utility model is to provide a kind of multi-channel parallel optical assembly of monitoring backlight.It utilizes the sloping optical fiber of plated film, and the part light in light path is drawn, and imports in back light detector, realizes monitoring backlight.This parallel light assembly does not need light path to change greatly, thus can deteriorated original device performance, can also be by film thickness monitoring backlight and bright dipping ratio, and inclined-plane fine make simple, technical maturity and cost performance high.
For reaching above-mentioned purpose, the technical scheme of the utility model application is: a kind of multi-channel parallel optical assembly of monitoring backlight, comprise insulating body, fiber array, lens, laser instrument, back light detector and excessive piece, wherein: described insulating body is provided with inclined-plane, optical-fibre channel and guide hole, described optical-fibre channel wherein a port through inclined-plane, and termination form angle; Described fiber array assembly is in described optical-fibre channel, and the optical fiber head in angle is inclined-plane head, and this inclined-plane head is coated with reflective coating; The corresponding guide hole of described lens is provided with leads a post; The corresponding lens of incident beam of described laser instrument, padded this back light detector installing of described transition block, this back light detector is arranged on the position that described reflective coating can reflex to.
Preferred in the present embodiment, described inclined-plane and the angle of inclination of surface level are 45 °.
Preferred in the present embodiment, described optical-fibre channel and described guide hole angle are 15 °.
Preferred in the present embodiment, described laser instrument adopts VCSEL array chip.
Preferred in the present embodiment, described MPO head is arranged at the other end of the fiber array of the multi-channel parallel optical assembly of this monitoring backlight.
Compared with prior art, its useful effect is the utility model:
Without the structure that changes lens and laser instrument, only need add outside a customization sloping optical fiber joint and just can complete, effective effect that its technique is simple, with low cost, workable.
