The optical cable terminal box according to the present invention is implemented to modularize a plurality of subscribers introduced from the outside into a small number of subscriber groups, and as shown in the drawing, the inner periphery of the outer enclosure 1 having a predetermined size A plurality of first and second distribution optical cable lengths 1a and 1b are mounted so as to be spaced apart at a predetermined interval so as to wind and process the optical cable drawn in from the outside and to be pulled out again. Here, an inner side of the second distribution optical cable length piece 1b is formed with a recessed portion 2a of a predetermined size at one side thereof, and an optical cable terminal module having a plurality of support holes 2b formed at a predetermined position thereof. (2) is mounted, and the optical cable terminal module (2) is divided into the loose tube by the optical tube treated by the loose tube from the first distribution optical cable piece (1a) to connect and distribute by the optical cable for inlet to protect the dressing.

In each of the support holes 2b of the optical cable terminal module 2, as shown in FIG. 2E, a support rod 3 having a male screw portion 3a formed therein at an upper end portion is inserted into the upper end portion, and the support rod 3 is provided. The optical cable terminal module 2 is supported, but the optical cable terminal module 2 is stacked by the height of the outer case 1. Here, as shown in FIG. 2f, a lattice connecting rod 4 having a female screw portion 4a formed at one side is fastened to the male screw portion 3a of the supporting rod 3, and the connecting rod 4 is When connecting, distributing and maintenance of the optical cable, it functions as a rail of the slide rotation so that the laminated optical cable terminal module (2) can be separated one by one from the outer housing (1).
