Abstract: It is disclosed an optical cable (1, 2, 3, 4, 5, 6) comprising an optical core (100, 200, 300, 400, 500, 600) and an external sheath (101, 201, 301, 304, 305, 306)surrounding the optical core. The external sheath comprises a first material having a first, higher fracture toughness and a second material having a second, lower fracture toughness. The first and second materials are arranged so that the second, lower fracture toughness material is accessible from outside the cable along at least one longitudinally extending area of the sheath outer surface. For accessing the optical core of the cable, a short longitudinal cut (namely, few centimetres) is made with a blade in the accessible second, lower fracture toughness material. Then, its cut edges are pulled apart by hand. The pulling force causes the lower fracture toughness material to fracture, thereby propagating the initial short cut longitudinally along the sheath through its whole thickness.
