METHOD FOR WINDING OPTICAL CABLE AROUND AERIAL WIRE

摘要

PURPOSE:To prevent a wound optical cable from twisting and to prolong its service life by unwinding the optical cable from a bobbin while revolving the bobbin around the aerial wire and then winding the optical cable around the aerial wire. CONSTITUTION:en the optical fiber 4 is unwound from the bobbin 1 while the bobbin 1 is revolved around the aerial wire 3 by a winder 2 and then wound around the aerial wire 3, the optical cable 4 is so unwound so that a twist reverse to a twist which is generated when the optical fiber is wound once around the aerial wire 3 at a pitch of about 30-40cm is given once for every 30-40cm, and the optical fiber 4 is taken up around the bobbin 1 while a payoff drum 5 is rotated. While this bobbin 1 is revolved around the aerial wire 3, the optical cable 4 is unwound from the bobbin 1 and wind around the aerial wire 3. Therefore, the optical cable 4 wound around the aerial wire 3 is not twisted or twisted a little. Consequently, the service life of the optical fiber 4 is prolonged.
