A fiber inlet () which is delimited by the first circumferential surface () and the first drive belt section () contacts the first circumferential surface (). A fiber outlet () which is delimited by the second circumferential surface () and the second drive belt section () contacts the second circumferential surface (), and a guide () passes the optical fiber () from the fiber inlet () to the fiber outlet ().
