WebSep 21, 2024 · Fusion splicing consists of aligning and permanently fusing stripped, cleaned and cleaved optical fibers with a high-temperature arc. Mechanical splicing utilizes an alignment device and index matching gel with a similar refractive index and covers the possible air gaps, helping light travel from one fiber to another. WebDec 10, 2024 · Dirt and dust can completely obscure a fiber light wave and create huge losses. Typically, connector loss can vary from 0.15 dB (LC) to 0.5 dB (ST-II). Calculating for a 0.5 dB loss per connector is common and typically represents the worst case scenario, assuming that a cleaned and polished connector is used.
