Abstract: An optical fiber coating stripper includes a pair of electrodes, each of which having a discharge head portion and an electrode portion, and a gliding plasma (GP) head housing the electrodes therein. The GP head includes internal airflow channels. The pair of electrodes are disposed at a front end of the GP head and form an air gap therebetween. Each of the discharge head portion includes a curved portion with a rib-shaped protrusion extending in a longitudinal direction of the discharge head portion. In operation, the electrodes are connected to non-alternating electrically positive and negative polarities. When a gas flows through the internal airflow channels in a direction a back end of the GP head toward the front end, a tongue-shaped GP flow is formed in the air gap between the rib-shaped protrusions of the discharge head portions.
