The invention provides a vibration sensing optical cable used for a perimeter surface and a perimeter security system. The vibration sensing optical cable used for the perimeter surface includes a plurality of cable cores, a first steel belt and an outer layer sheath; each of the plurality of cable cores includes at least one optical fiber and an inner layer sheath that wraps at least one optical fiber, and the plurality of cable cores are arranged to be mutually parallel; the first steel belt is parallel to the plurality of cable cores; the outer layer sheath wraps and fixes the plurality of cable cores and the first steel belt; and the width direction of the first steel belt is parallel to a side face of the outer layer sheath which is in contact with the perimeter surface. The optical cable has relatively high structural strength, and the sensitivity of the optical cable to vibration monitoring is improved. 本发明提供种用于周界表面的振动传感光缆以及周界安防系统。种用于周界表面的振动传感光缆，包括：多个缆芯，多个缆芯中的每个缆芯包括至少根光纤和包覆至少根光纤的内层护套，多个缆芯设置成彼此平行；第钢带，第钢
