研究了一种可能适合于某种光缆野外连接的技术,这种光缆由导光纤维的线性阵组成。线性排列的纤维(纤维也可以处于纤维条片中),放在顶端和底都都开有凹槽的垫片之间,形成堆积起来的矩形阵列。这道工序可以在不用显微镜或显微操作设备的条件下进行。在灌封好以后,二个堆积阵列的末端就进行抛光而成为光缆终端,他们在一个对接接头中放在一起。使用此技术的12×12阵列的138个接头的平均损耗为0.42分贝,其中70%的损耗小于0.5分贝.后来的单根条片到条片接头的平均损耗小于0.2分贝。装入的条件可以重复,重新装配的接头的连接损耗厦复多次都是低的。这大概是出于抛光的纤维末端及准确对准的缘故。迄今所取得的经验表明,这种总体接头方法大概将产生最大损耗为0.5分贝的大型阵列接头。
A technique that may be suitable for the field connection of some kind of fiber optic cable is studied, which consists of a linear array of light guiding fibers. Linearly arranged fibers (the fibers may also be in the fiber strip) are placed between the top and bottom grooved gaskets to form a stacked rectangular array. This procedure can be carried out without the use of a microscope or micromanipulator. After potting, the ends of the two stacked arrays are polished to become cable terminations, which are put together in a butt joint. The average loss for the 138 connectors of the 12 × 12 array using this technique was 0.42 dB, with 70% of the losses less than 0.5 dB. The subsequent average loss per strip to tab splice was less than 0.2 dB. The loading conditions can be repeated, the connection loss of the reassembled connector is low many times. This is probably due to polished fiber ends and accurate alignment. The experience gained so far shows that this overall joint approach will probably result in a large array connector with a maximum loss of 0.5 dB.
