Abstract
Novel tools and techniques are provided for implementing remediation of lead sheathed installed telecommunications cables. In various embodiments, a remediation tool, which is configured to move within an inner portion of lead sheathing for installed telecommunications cables, includes a microcontroller device, a connector configured to connect with a compressed air hose configured to direct compressed air from an external compressed air source to an interior portion of the remediation tool, a transducer configured to convert motion from compressed air that is input via the connector into electrical power. The remediation tool further includes a material removal tool configured to remove material from at least one of the inner portion of the lead sheathing or the lead sheathing itself, one or more sensors, and a propulsion system configured to propel the remediation tool in a forwards and/or backwards direction within the inner portion of the lead sheathing for installed telecommunications cables.
