In this paper, insertion losses (coupling losses) of the SMA type optical connector are measured for some combinations of its housings and ferrules. It is well known that the insertion loss between two butt jointed fibers with connector is depend on axial and angular misalignments between two fibers. But by this measurement we have been able to show housing (plug and nut) of the SMA type connector, as axial and angular misalingment, affects the insertion loss between two fibers. In this experiment, we prepared eight housings and three ferrules, and measured the insertion loss for all of the housing-ferrule combination. The insertion loss is measured at each 45 degrees of the connection angle, and 30 times at each point. Therefore, 240 times measurements are taken for one housing-ferrule combination. From these measured values, we can obtain the result that the measured values and its deviations vary due to exchange the housing.
