The fiber should instead be re-cleaved to achieve a fresh contaminant free facet. Re-cleaving can be avoided by using connectorized fiber with sealed, cleanable end-facets (see more information about connectors and end-sealing in the section on Connectors). The result of soaking a fiber is excessive swelling which can cause a loss of adhesion between the acrylate coating and the glass cladding of the fiber. " If the fiber is soaked for a long enough period, wicking of the. The procedures in this document describe basic inspection techniques and processes of cleaning for fiber optic cables, bulkheads, and adapters used in fiber optic connections. Splices shall be stable over the design life of the system under its expected environmental conditions. At present, two technologies, fusion and mechanical, can be used for. The drying procedures for residual alcohol, and ultimately residual moisture, are difficult at best. Since isopropyl alcohol is relatively slow to dry, it can attract more airborne contamination. With fiber optics, the tolerance to dirt or contamination on the ends of the ferrules of a connector is near zero. Airborne dirt particles are about the size of the core of SM fiber and are usually silica based - they may scratch PC connectors if not removed! Patch panels have mating adapters that. Mechanical splicing means that two fiber ends are tightly held together with some mechanical means.
