Fusion splicing uses a precision arc discharge between two electrode rods to heat and fuse the cleaved fiber ends together. Unlike a patch cord—which has connectors on both ends—the bare fiber end of a pigtail is designed to be permanently spliced (either by fusion or. Fiber splicing means joining two optical fibers (permanently or temporarily) such that light guided in one fiber and reaching the joint (splice) can be transferred into the second fiber with low insertion loss. Instead of building a connector from scratch in the field, you simply fuse the “bare” end of the pigtail to. By combining factory-installed connectors with spliced bare fiber, pigtails ensure that network installers can create fast, reliable, and cost-effective terminations. Without pigtails, every termination in an ODF, terminal box, or splice closure would require field-installed connectors—an approach. Fiber optic joints or terminations are made two ways: 1) splices which create a permanent joint between the two fibers or 2) connectors that mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear. The traditional approach to fusion splicing.
