Method and system for manufacturing optical fiber ribbon

A manufacturing method for manufacturing an optical fiber ribbon, the manufacturing method comprising:

• intermittently forming, with a connecting device, connection parts between optical fibers;
• measuring a load of the connecting device during the intermittent forming of the connection parts;
• and
• detecting an abnormality based on the load, wherein
• the connecting device includes a dispenser that applies a connecting agent, and
• the manufacturing method further comprises:
• measuring a load of an actuator of the dispenser;
• and
• detecting the abnormality based on the load of the actuator.

A manufacturing system for manufacturing an optical fiber ribbon, the manufacturing system comprising:

• a connecting device that intermittently forms connection parts between optical fibers;
• a measurer that measures a load of the connecting device during the intermittent forming of the connection parts;
• and
• a controller that detects an abnormality based on the load, wherein
• the load is a torque of a motor in the connecting device,
• the connection parts comprise a separating unit that intermittently separates the optical fibers,
• the load is the torque of the motor that drives the separating unit, and
• the measurer further measures a rotation position of a rotary blade in the separating unit, and
• the controller detects the abnormality in layout of the connection parts based on the torque and the rotation position.
