The anchoring assembly has a head and tail each having a throughbore with anchor receiving portions. An anchor with a deformable portion maybe inserted into the anchor receiving portions and the head and tail drawn together about the anchor. The anchor receiving portions have a narrowing diameter, which, upon abutment with the anchor causes the deformable portion of the anchor to deflect inward and secure a cable inserted therein. A conductive body is provided in the head or tail for coupling with the cable and providing a conductive pathway to a downhole tool. ## Claims ### Claim 1 An anchoring assembly comprising: a head and a tail each having a throughbore extending from a proximal end to a distal end, the throughbore of each of the head and the tail having an anchor receiving portion narrowing in diameter as it extends from the proximal end toward the distal end of each of the respective head and tail; an inner anchor having a deformable portion and a central throughbore with a central axis; and a conductive body coupleable with the head or the tail, the conductive body having a conductive throughbore, the inner anchor receivable in the anchor receiving portions of the head and the tail, with the proximal ends of the head and the tail facing one another, the deformable portion of the inner anchor deflectable toward the central axis upon abutment with the narrowing diameter of the anchor receiving portion of the head or the tail. ### Claim 2 (depends on 1) The anchoring assembly of claim 1, wherein the head and the tail are non-conductive. ### Claim 3 (depends on 1) The anchoring assembly of claim 1, further comprising an electrical terminal coupleable with the conductive body. ### Claim 4 (depends on 1) The anchoring assembly of claim 1, further comprising a cable having an optical fiber, the cable insertable into the throughbore of each of the head and the tail, the central throughbore and the conductive throughbore. ### Claim 5 (depends on 4) The anchoring assembly of claim 4, wherein the cable comprises: a core containing the optical fiber, an inner metal tube positioned around the core, an electrical conductor positioned around the inner metal tube, an outer tube positioned around the electrical conductor, and wherein the electrical conductor couples with the conductive body forming an electrical pathway when inserted within the anchoring assembly. ### Claim 6 (depends on 1) The anchoring assembly of claim 1, wherein the anchor receiving portion of each of the head and the tail has a frustoconical shape. ### Claim 7 A method comprising: inserting a cable into an anchoring assembly, the anchoring assembly comprising: a head and a tail each having a throughbore extending from a proximal end to a distal end, the throughbore of each of the head and the tail having an anchor receiving portion narrowing in diameter as it extends from the proximal end toward the distal end of each of the respective head and tail, an inner anchor having a deformable portion and a central throughbore with a central axis, and a conductive body coupleable with the head or the tail, the conductive body having a conductive throughbore;
