Mongolian Fiber Optic Cable Fusion Splicing Series

Fusion splicing in Mongolia follows international best practices while adhering to local standards such as MNS 5207:2023, ensuring high-quality, low-loss fiber optic connections.

Overview of Fusion Splicing

Fusion splicing is the process of welding two optical fibers together using an electric arc, creating the strongest and most reliable joint with minimal signal loss and reflectance . It is widely used for single-mode fibers, which dominate long-distance and high-speed networks, while multimode fibers require more careful alignment due to their larger cores . Splicing can be performed one fiber at a time or as a ribbon splice, where multiple fibers are fused simultaneously .

Equipment and Techniques

Modern fusion splicers, such as those from Fujikura, offer core alignment for high precision and cladding alignment for portability . Ribbon splicers often use profile alignment, while single fibers may use LID core alignment, which measures light transmission to optimize fiber alignment . Key equipment includes:

• Precision fiber cleavers to ensure clean, perpendicular cuts
• Fusion splicer machines with automated alignment and heating for protective sleeves
• Cleaning tools such as lint-free wipes, isopropyl alcohol, and fiber cleaning pens to prevent contamination Proper handling, including anti-static precautions, controlled tension, and careful placement in V-grooves, is essential to minimize splice loss .

Mongolian Standards and Installation Practices

In Mongolia, fiber optic cable installation follows MNS 5207:2023 and related standards, covering:

• Communication well channeling infrastructure for urban planning and expansion
• Micro-trenching, which involves narrow, shallow trenches for urban fiber deployment
• Underground installation using armored cables according to MNS 6597:2016, MNS 5207:2016, and MNS 5278:2003
• Aerial installation on poles for conventional and special-purpose cables These standards ensure durable, high-capacity networks suitable for telecommunications, internet backbones, and data centers.

Best Practices for High-Quality Splicing

• Fiber preparation: Strip coatings carefully (typically 250µm for bare fibers, 900µm for coated fibers) to avoid microfractures
• Cleaning: Thoroughly clean fiber ends to remove dust, oil, or residue
• Cleave verification: Use microscopes to ensure flat, perpendicular cleaves with minimal chips or cracks
• Splice alignment: Use automated core alignment or LID systems to achieve optimal light transmission
• Protective sleeves: Heat-shrink sleeves over splices to prevent moisture and environmental damage

Conclusion

The Mongolian Fiber Optic Cable Fusion Splicing Series integrates advanced fusion splicing techniques with local installation standards, ensuring reliable, low-loss fiber connections. By combining precision equipment, proper handling, and adherence to MNS standards, technicians can achieve high-performance fiber optic networks suitable for urban, rural, and industrial applications .
