Optical fiber cable having non-metallic sheath system. |
摘要 |
<p>An optical fiber cable (20) includes a core (22) comprising at least one optical fiber which is enclosed in a tubular member (28) and which includes a non-metallic sheath system (30). The sheath system includes two contiguous layers (40, 50) of non-metallic strength members which extend longitudinally along the cable and which are wrapped helically in opposite directions about the tubular member. The layers of strength members are enclosed in a plastic jacket (36). At least some of the strength members which are capable of withstanding expected compressive as well as tensile loading are coupled sufficiently to the jacket to provide a composite arrangement which is effective to inhibit contraction. Those strength members cooperate with the remaining strength members to provide the cable with a predetermined tensile stiffness and to cause the cable to be relatively flexible.</p> |
