- Sheath Stripping: Use proper stripping tools to remove the outer jacket without nicking the buffer tubes or scoring the internal glass fibers. - Cleaning Protocol: Clean bare fibers thoroughly using 99% Isopropyl Alcohol (IPA) and lint-free wipes before cleaving. Never touch bare fiber with your fingers after cleaning. - Precision Cleaving: Ensure the fiber cleaver is clean and maintained. Target a cleave angle of less than 0.5 degrees for optimal fusion results.

- Splicing Threshold: The maximum allowable splice loss per joint must not exceed 0.05 dB. Re-splice immediately if the machine detects a higher loss. - Protection Sleeves: Center the heat-shrink protective sleeve over the splice point before activating the fusion splicer's heating oven. Ensure no air bubbles remain inside. - Tray Routing: Maintain a minimum bending radius inside splice trays to avoid microbending. Secure buffer tubes loosely with mini-tie wraps; do not overtighten. - Enclosure Sealing: Apply proper rubber seals and tightening torque to dome or inline enclosures to guarantee a 100% waterproof seal against weather elements.

- End-to-End OTDR Testing: Conduct bi-directional Optical Time-Domain Reflectometer (OTDR) traces at both 1311nm and 1550nm wavelengths to map the entire link profile. - Splice & Connector Reflection: Ensure all optical connectors have a reflectance value better than -50 dB to prevent severe backreflection into the transmitter.
