The invention discloses a communication cable branching and sequencing device, which relates to the technical field of wiring. The device comprises a detection mechanism, a sequencing mechanism and acontroller, wherein the sequencing mechanism comprises an operation platform, a moving system, a fixing clamp, a branching table and a branching clamp; the branching clamp comprises a main arm; two movable hooks arranged in parallel are arranged on the main arm; the bottom end of the main arm is provided with a first slide way movably matched with hook handle parts of the movable hooks; a telescopic motor C is arranged in the first slide way; the end of the telescopic motor C is connected to the hook handle parts of the movable hooks; a movable rod is fixed to the end face of the hook handle part of the movable hook; a top block matched with the arc-shaped hook body of the movable hook is further arranged at the bottom end of the main arm; the bottom side face of the top block is of a cambered surface structure; the branching table comprises a plate body; a movable plate is arranged on the plate body in a matched mode; and a plurality of wire core clamping grooves are formed in the plate body along the length direction. Branching and sequencing are carried out on the cores of the communication cables, the detection system is adopted to assist in identifying branching, and unmannedoperation in the whole process is realized.
