The invention discloses a quick optical cable tester which comprises a testing meter and an optical fiber butt joint device. The quick optical cable tester is characterized in that the optical fiber butt joint device comprises a base plate, a V-shaped groove is formed in the middle in the length direction of the base plate, cable grooves are formed in the left part and the right part in the length direction of the base plate, the cable groove in the left part and the cable groove in the right part are both communicated with the V-shaped groove, and a left press cover, a middle press cover and a right press cover are arranged on the upper part of the base plate. The optical fiber butt joint device of the quick optical cable tester is exquisite in design, simple in structure, flexible in operation and portable. The optical fiber butt joint device and an OTDR are used in a coordination mode, so that optical fiber and tail fiber are made to be in butt joint temporarily in a coupling mode, and fusion welding is not needed. Compared with the prior art, the quick optical cable tester saves optical fiber connecting time, effectively improves working efficiency, reduces testing cost, greatly reduces device consumption, can meet the requirements of optical fiber tests in different places, and is especially suitable for inspection of incoming optical cables, optical cable failure first-aid repair, and the like.
