摘要： The disclosure provides optical fiber cable manufacturing equipment including a collective core portion including a plurality of optical fibers, a metal tape disposed outside the collective core portion, and a sheath portion disposed outside the metal tape, the optical fiber cable manufacturing equipment including: a pre-bonding portion configured to pre-bond the metal tape to the outside of the collective core portion; a first coating portion disposed behind the pre-bonding portion to coat a first adhesive over at least part of both ends of the metal tape; a bonding portion disposed behind the pre-bonding portion to bond the metal tape to the outside of the collective core portion with the both ends of the metal tape overlapping each other; a second coating portion disposed behind the bonding portion to coat a second adhesive over the outside of the metal tape; and a sheath fabrication portion disposed behind the second coating portion to cover the collective core portion to which the metal tape is bonded, with a sheath, wherein an upper portion of the collective core portion to which the metal tape is bonded is heated before the collective core portion to which the metal tape is bonded enters the second coating portion, wherein the second adhesive is coated only over a lower portion of the collected core portion to which the metal tape is bonded in the second coating portion, wherein a melting point of the first adhesive is higher than a melting point of the first adhesive.
