Sumitomo Type 39 Fusion Splicer

The Sumitomo Type 39 Fusion Splicer is a core alignment splicing system designed for precise fiber joining. It is used in metro, backbone, long haul and specialty fiber applications where low splice loss is important. The Type 39 supports micro core and standard fibers when correct splice programs are selected. Its combination of alignment control, arc calibration and field ready construction makes it suitable for installation and maintenance teams.

Core Alignment and DCM Control

The Type 39 uses core alignment to position fibers before arc fusion. This helps match the light carrying region and reduces splice loss. DCM based control supports detailed monitoring of the splice process. It is especially useful for micro core fibers, where alignment accuracy is critical. The system helps produce consistent results across different fiber types and batches.

Arc Calibration

Arc conditions change with electrode wear, temperature, humidity and altitude. The Type 39 includes calibration functions to compensate for these variables. Automatic arc calibration helps maintain stable fusion energy. This supports low loss splicing and helps prevent weak joints. Technicians can select arc programs based on fiber type and environmental conditions.

Splicing Workflow

A typical workflow begins with coating removal and cleaning. Fibers are cleaved to a precise angle and loaded into the splicer. The Type 39 aligns the cores, applies the arc and estimates splice loss. After splicing, the joint is protected with a splice protector sleeve and heat shrink oven. The splicer records splice results for quality control. This structured process helps teams maintain high yield.

Field Applications

The Type 39 is suitable for metro rings, backbone routes, long haul links, utility networks and specialty fiber projects. It can be used in central offices, controlled environments and field locations. Its design supports maintenance and restoration work where accurate splicing is required. It is also useful for projects involving micro core fibers, bend insensitive fibers and mixed cable types.

Operational Reliability

Reliability in the field depends on a stable platform, protected optics and a durable body. The Type 39 is built to support repeated field use. Protective covers, carry cases and battery operation help technicians work in different locations. The user interface provides access to splice modes, heat modes and data records. Stored results can support quality reporting and project documentation.

Maintenance Requirements

Regular cleaning is essential. V grooves, clamps, electrodes and objective lenses should be kept free of dust and fiber debris. Electrodes should be replaced according to splice count and arc quality. The battery should be maintained properly, and the unit should be stored in a dry environment. These steps help preserve alignment accuracy and arc stability.

Conclusion

The Sumitomo Type 39 Fusion Splicer is a specialized tool for high precision fiber splicing. It combines core alignment, DCM control and field ready construction. It is a strong option for metro, backbone and specialty fiber work that requires consistent low loss results.
