6.1 光缆接续的一般要求为了用多根制造长度的光缆构成光传输线路,就必须进行接续.使用电缆的经验表明,故障大多发生在接头上或接头附近,因此光缆通信系统也应当充分注意这一点,一方面应当尽量减少接头数目,另一方面应采用有效而可靠的接续技术.对光缆接续的一般要求有:①接头所引起的附加损耗小;②接头的可靠性高,具有良好的机械性能,如抗拉特性好,对接头以外的光纤无损伤等,以保证长期稳定特性;③在现场施工中要求接续时间短、操作筒单;④成本低廉等.
6.1 General requirements for fiber optic cable connection In order to form an optical transmission line with multiple lengths of fiber optic cable, it is necessary to continue the connection. Experience with cables has shown that failures occur mostly at or near the connector, so cable communication systems should also take full account of this , On the one hand should be to minimize the number of joints, on the other hand should be effective and reliable continuation of the technical requirements of the continuation of the cable are: ① additional loss caused by joints is small; ② joints of high reliability, good mechanical properties , Such as good tensile properties, no damage to the fiber outside the connector, etc., to ensure long-term stability characteristics; ③ in the field of construction requires a short follow-up, the operation of a single; ④ low cost.
