ANCHORING METHOD OF OPTICAL EXTERIOR WIRE

摘要

PURPOSE:To prevent tensile force and compressive force due to temperature fluctuations from operating on an optical fiber core by covering the coating part of the optical fiber core which is cut and separated with a guide for the optical fiber core of an optical exterior wire, and restraining the coating part of the optical fiber core. CONSTITUTION:When the optical exterior wire 1 is drawn and anchored to a wall surface 2 of the main house, the optical exterior wire anchor 4 is fitted to a hook bolt 3 embedded in the wall surface 2 and then the optical exterior wire 1 is cut and separated into the steel wire coating part 6 and coating part 8 of the optical fiber core 7 to wind the steel wire coating part 6 around the optical external wire anchor 4. Then, the guide 9 for the optical exterior wire optical fiber core is fitted to the coating part 8 of the optical fiber core and optical exterior wire separation anchors 10 are fitted to both ends while covering the optical exterior wire 1 and guide 9 and the opening parts of the anchors 10 are closed by the caulking of cutting pliers.
