## FIBER OPTIC DEPLOYMENT & SPLICING STANDARDS

## 1. Fiber Cable Preparation & Handling

<div id="bkmrk-sheath-stripping%3A-us"><div>  
</div>- <span>Sheath Stripping</span>: Use proper stripping tools to remove the outer jacket without nicking the buffer tubes or scoring the internal glass fibers.
- <span>Cleaning Protocol</span>: Clean bare fibers thoroughly using 99% Isopropyl Alcohol (IPA) and lint-free wipes before cleaving. Never touch bare fiber with your fingers after cleaning.
- <span>Precision Cleaving</span>: Ensure the fiber cleaver is clean and maintained. Target a cleave angle of less than 0.5 degrees for optimal fusion results.

</div>## 2. Fusion Splicing &amp; Enclosure Management

<div id="bkmrk-splicing-threshold%3A-"><div>  
</div>- <span>Splicing Threshold</span>: The maximum allowable splice loss per joint must not exceed <span>0.05 dB</span>. Re-splice immediately if the machine detects a higher loss.
- <span>Protection Sleeves</span>: Center the heat-shrink protective sleeve over the splice point before activating the fusion splicer's heating oven. Ensure no air bubbles remain inside.
- <span>Tray Routing</span>: Maintain a minimum bending radius inside splice trays to avoid microbending. Secure buffer tubes loosely with mini-tie wraps; do not overtighten.
- <span>Enclosure Sealing</span>: Apply proper rubber seals and tightening torque to dome or inline enclosures to guarantee a 100% waterproof seal against weather elements.

</div>## 3. Optical Link Testing &amp; Commissioning

<div id="bkmrk-end-to-end-otdr-test"><div>  
</div>- <span>End-to-End OTDR Testing</span>: Conduct bi-directional Optical Time-Domain Reflectometer (OTDR) traces at both 1311nm and 1550nm wavelengths to map the entire link profile.
- <span>Splice &amp; Connector Reflection</span>: Ensure all optical connectors have a reflectance value better than <span>-50 dB</span> to prevent severe backreflection into the transmitter.
