Description
Technical Field
The utility model belongs to the communication subassembly field, in particular to BOSA subassembly with low costs, that light receiving efficiency is high.
Background
The BOSA component can receive light emitted by a laser through a plurality of lenses, because the existing BOSA component adopts a common laser, divergent light emitted by the BOSA component is changed into convergent light through a lens, the convergent light is changed into parallel light through a Glens (collimator lens), and the parallel light is changed into the convergent light through the Glens and can be received by a receiver (as shown in figure 2).
The to-be-solved technical problem of the utility model is to provide a take BOSA subassembly of semiconductor cooler that only needs a collimator lens, use cost is low, conversion light receiving efficiency is high, the built-in steel pipe encapsulation that need not of collimator lens, equipment simple to use is convenient, effectively satisfy operation requirement.
SUMMERY OF THE UTILITY MODEL
Need to use two Glens and Glens high price, product use cost height, light through twice conversion efficiency low, Glens setting need increase a steel pipe outside the base and encapsulate, the equipment is used and also troublesome more, can't satisfy operation requirement scheduling problem for solving above-mentioned prior art, the utility model discloses a following technical scheme:
the utility model provides a BOSA component with a semiconductor refrigerator, which comprises a refrigeration type flat window laser, a laser tube body, a convex lens, a three-way base, an isolator, a detector, a wave plate group, a coupling wave plate, a collimator lens, a glass tube, a heat shrink tube and a pair of connectors, wherein the refrigeration type flat window laser is arranged at the tail part of the laser tube body, the laser tube body is arranged on a left connector of the three-way base, the convex lens is arranged in the three-way base through the lens tube body, the isolator is arranged in the three-way base through the isolator tube body and is positioned right in front of the convex lens, the detector is arranged on a connector on the three-way base, the wave plate group is integrally formed in the three-way base and is positioned under the detector, the glass tube is arranged on a right connector of the three-way base through a transition block, the coupling wave plate and the collimator lens are sequentially arranged in the glass tube from left, the convex lens, the isolator, the wave plate group, the coupling wave plate and the collimator lens are located on the same horizontal straight line, the pair of connectors are communicated with the glass tube light path through optical fibers, and heat-shrinkable tubes are arranged on the optical fibers.
The beneficial effects of the utility model reside in that: the low-cost convex lens is added, so that divergent light emitted by the laser is directly changed into parallel light, and then the parallel light can be received only through the collimator lens, the use cost is low, the primary conversion light receiving efficiency is high, the collimator lens is internally arranged without steel tube packaging, the assembly and the use are simple and convenient, and the use requirements are effectively met.
