  • Fiber optic ribbon interconnect cable
    Publication number: 20020186939
    Abstract: A fiber optic cable comprising an optical ribbon (20), a jacket (40), and a buffer material (30) between the optical ribbon (20) and the jacket (40). Buffer material (30) includes at least one volume of buffer material defining a stress-cushioning zone (32) between optical ribbon (20) and jacket (40), the stress-cushioning zone being operative to substantially decouple jacket (40) from ribbon (20) in the region of the stress-cushioning zone (32) thereby inhibiting the application of stress to optical ribbon (20). Buffer material (30) includes at least one volume of material at an intermediate buffer zone (35) held substantially tight against an intermediate portion (25) of optical ribbon (20) for inhibiting the twisting of optical ribbon (20). The volume of material at the stress-cushioning zone (32) is substantially larger than the volume of the buffer material of the intermediate buffer zone (35).
