High-intensity bending-resistant optical cable

The invention relates to a high-intensity bending-resistant optical cable. The optical cable comprises four communication cores, an inner sheath, a water-blocking tape, a metal armor layer and an oversheath; and each communication core comprises fiber beams, insulating fiber paste is filled among the fiber beams, the inner sheath is extruded outside the four communication cores to form a cable core, the water-blocking tape is arranged outside the cable core, the metal armor layer is arranged outside the water-blocking tape, and the oversheath is arranged outside the metal armor layer. The optical cable is simple in structure, low in production cost, high in physical intensity, long in service life, and wide in adaptive areas. 本发明涉及种高强度耐折弯光缆。所述的光缆包括四根通信线芯、内护套、阻水带、金属铠装层、外护套，所述的通信线芯包括若干光纤束，所述的若干光纤束之间满填充绝缘纤膏，所述的内护套挤包在四根通信线芯外构成缆芯，所述的缆芯外设置阻水带，所述的阻水带外设置金属铠装层，所述的金属铠装层外设置外护套。本发明结构简单、生产成本低、物理强度高、使用寿命长、适应地区广。
