Wherein, metal compound belt is steel band.
Wherein, metal compound belt is aluminium strip.
Wherein, the expanded material bed course is the ethylene-vinyl acetate copolymer bed course.
Wherein, the unit cable also comprises loose sleeve pipe, loose sleeve pipe clad optical fiber.
Wherein, loose cannula cavity is provided with fine cream.
Wherein, also comprise gasket for packing, gasket for packing is positioned at the inner chamber of metal compound belt.
Wherein, the quantity of unit cable is the 1-15 root, and the quantity of gasket for packing is the 1-4 root, unit cable and gasket for packing evenly be arranged on metal reinforcement around.
Wherein, the quantity of the optical fiber of every root unit cable is the 4-12 root.
