At this time, each terminal of the connector and the cross section of the optical cable to be connected should not be contaminated by foreign substance, and the optical signal transmitted to the optical cable should not fall below a predetermined reference value due to disconnection of the optical cable or bending exceeding the allowable limit.

Therefore, the field worker must inspect the cross-section of the optical fiber (optical fiber) using a microscope or the like before the connection operation of the optical cable to check the contamination, and if it is contaminated, the contamination must be removed by using a special cleaner or the like, And for this purpose an optical fiber inspection apparatus is used.

However, since the conventional optical fiber inspection apparatus has to be individually checked by a microscope operator, it takes a long time for the operation and the efficiency of the work is low, which is not suitable for mass production.

On the other hand, an optical cable that is wrapped by a coating of a certain thickness must perform coating removal and optical cable cleaning and cutting processes in order to fabricate an optical cable and to make fusion splicing connection.
