Using alcohol wipes is the recommended method for cleaning the end of fiber optic cables. Alcohol wipes effectively remove dust, oils, and other contaminants that can impede the performance of the fiber optic connection. The use of isopropyl alcohol, in particular, helps to dissolve residues and evaporates quickly, preventing any moisture from lingering on the fiber ends, which is crucial for maintaining optimal signal transmission quality.

Cleaning fiber optic cables with alcohol wipes also helps in ensuring that no lint or fibers from other cleaning materials are left behind, which could cause issues in signal transfer. It’s important to maintain a clean surface on connector ends, as contaminants can lead to increased loss and reflection of signals, thereby affecting overall network performance.

Other cleaning methods may not be as effective or safe for fiber optics. For instance, using soap and water could leave residues or require more drying time, which isn't ideal. A dry cloth without cleaning agents might not sufficiently remove oils or sticky residues, risking damage or performance issues. Compressed air can dislodge dust but does not effectively clean any oils or residues that might be present, and can potentially blast debris further into the connector instead of removing it. Thus, alcohol wipes remain the optimal choice in maintaining the integrity and performance of fiber optic connections
