The invention discloses a cable splicing operation platform comprising a platform body with support legs. Two ends, in the horizontal direction, of the top of the platform body are provided with a groove for accommodating a splicer and a U-shaped clamping board for fixing a cable joint box. A rectangular fixing groove is formed at the inner top of the U-shaped clamping board and matches with a disc part of the cable joint box. Wind boards are arranged at a cable inlet of the platform body and on adjacent two sides. By the aid of the cable splicing operation platform, splicing workers can set up and place splicing equipment conveniently under various conditions, the cable splicer, an OPGW (optical fiber composite overhead ground wire) cable and the joint box can be fixed, cable breakage or core breakage due being mistakenly hit by external forces can be avoided, safe cutting and splicing of the cables can be guaranteed, the reliability rate, quality and efficiency of cable splicing can be increased, and quality and efficiency of cable splicing can be improved. The cable splicing operation platform can be assembled rapidly, and is adaptable to terrains, convenient to operate and carry, reasonable in structure, light in weight, durable and consistent to splicing specifications.
