由於光纖本身係細小且容易斷裂破損的玻璃材質，因此在光纖對準與固定前（尤其以雷射銲接技術固定光纖）經常需將光纖固定在一個可提供保護的套管內。製作方法係以銲錫（鉛錫或金錫）技術將外表鍍金光纖焊接於金屬管內，形成光纖-銲錫-套管之光纖套管。因此在操作光纖對準步驟，僅處理光纖套管與雷射對準。光纖對準後，鞍型扣件扣住光纖套管，再利用雷射焊接方式將鞍型扣件、光纖套管與基座固定。蝶式雷射模組構裝由於耦光效率低，良率不高且技術門檻高，其關鍵技術為鞍型扣件與光纖套管與基座結合。本文設計一種新型鞍型扣件，新型鞍型扣件與光纖套管焊接結合部分為斜邊設計，可找到最佳焊點減少焊後位移。新型鞍型扣件與基座焊接固定部分為彎腳設計，利用彎腳可作耦光調整，焊接順序裕度與自由度增加，可先焊鞍型扣件與光纖套管再焊基座，也可先焊鞍型扣件與基座再焊光纖套管兩種方式，符合市面上兩種蝶式外型雷射模組構裝。新型鞍型扣件彎腳上端有頸縮設計，利用彈塑變形之塑性變形微調，提高耦光效率。新型鞍型扣件製作方法容易，且尺寸公差要求不高，可利用連續製造製作法，大量生產可大大降低構裝成本。

One's own department tiny easy to rupture damaged glass material because of optical fiber, so before the optical fiber is aimed at and fixed. Often need to fix the optic fiber in a sleeve pipe that can offer protection. The manufacture method is with the soldering tin. Plate appearance the golden light and weld finely in the metal pipe, form the optic fiber - the optic fiber sleeve pipe of soldering tin the sleeve pipe in technology. So is operating the optic fiber and aiming at the step, only deal with the sleeve pipe of optic fiber with aiming at laser weld. After the optic fiber is aimed at, saddle fastener deduct live in optic fiber sleeve pipe, utilize laser to weld way saddle fastener, optic fiber between sleeve pipe and regular base again. The butterfly laser model's constructs and puts because of the mere efficiency of coupling low, the high and technological threshold of the good rate is high, its key technology is combined with the base for saddle fastener and sleeve pipe of optic fiber. This plan designs a new-type saddle fastener. The new-type saddle fastener designed hypotenuse, can find optimum welding point to reduce weld-post-shift. The new-type saddle fastener standing part designed curve. The abundant degree of order and increase with the degree of freedom, can weld saddle fastener and sleeve pipe of optic fiber and weld the base again, can weld saddle fastener and base and weld two kinds sleeve pipes of optic fiber again first, accord with and construct and put in two kinds of butterfly laser model's packing on the market. New-type saddle fastener curve foot have neck is it design to contract. It is mould out of shape to raise the smooth efficiency of coupling to play to utilize. The new-type saddle type fastener manufacture method is easy, and the dimensional tolerance is expected much, but by making the law of making in succession, producing in a large amount can reduce and construct and put the cost greatly .
