Cable clamping devices and methods for using the same

A closure device for receiving a fiber optic cable, the cable having a lengthwise cable axis and including a plurality of optical fibers, a strength member and a jacket surrounding the optical fibers having a section thereof partially removed in a scalloped configuration that exposes an underlying section of the strength member while leaving a remaining portion of the jacket extending under the strength member to a longitudinal end of the remaining portion of the jacket and the strength member, the closure device comprising:

• an enclosure defining a splice chamber configured to accommodate splices to the plurality of optical fibers, the enclosure having a clamp receiving section therein;
• and
• a clamping device including:
• a receiving block having a cavity extending longitudinally therein from an opening in an end face of the block to a closed end of the cavity, wherein the cavity is configured to receive the end of the remaining portion of the jacket and the strength member through the opening in the end face of the block;
• and
• a coupling member configured to couple the block to a portion of the jacket not having a section thereof partially removed when the strength member is inserted into the cavity to limit longitudinal movement of the block relative to the jacket and buckling of the strength member,
• wherein the clamping device is configured to be removably inserted into the clamp receiving section of the enclosure and wherein the clamp receiving section is configured to fixedly limit movement of the clamping device relative to the enclosure when the clamping device is installed therein to secure the remaining portion of the jacket and the strength member inserted in the cavity and abutting the closed end of the cavity to the enclosure.

A method for securing a fiber optic cable to a closure device using a clamping device including a receiving block and a coupling member, the cable having a lengthwise cable axis and including a plurality of optical fibers, a strength member and a jacket surrounding the optical fibers having a section thereof partially removed in a scalloped configuration that exposes an underlying section of the strength member and the plurality of optical fibers while leaving a remaining portion of the jacket extending under the strength member to a longitudinal end of the remaining portion of the jacket and the strength member, the method comprising:

• inserting the remaining portion of the jacket and the strength member into an opening in an end face of the receiving block, wherein the receiving block includes a cavity extending longitudinally therein from the opening in the end face of the block to a closed end of the cavity and the remaining portion of the jacket and the strength member are inserted to a position, proximate the closed end of the cavity;
• securing the coupling member to a portion of the jacket not having a section thereof partially removed while the remaining portion of the jacket and the strength member are inserted into the cavity to limit longitudinal movement of the receiving block relative to the jacket and buckling of the strength member;
• inserting the clamping device with the remaining portion of the jacket and the strength member inserted in the cavity and proximate the closed end of the cavity into the clamp receiving section of the closure device to secure the jacket and the strength member to the closure device and fixedly limit their movement relative to the closure device;
• positioning the exposed plurality of optical fibers in a splice chamber of the closure device;
• and
• covering the splice chamber with the plurality of optical fibers therein.
