Sumitomo Type-39 Micro Core DCM Fusion Splicer

The Sumitomo Type-39 Micro Core DCM Fusion Splicer is a core alignment splicing system designed for precise fiber joining. It is associated with micro core fiber and DCM based alignment, making it suitable for networks that require low splice loss and reliable arc control. The Type-39 is used in metro, backbone, long haul and specialty fiber applications where fiber geometry and core position must be managed carefully.

DCM and Micro Core Fiber

DCM technology supports detailed observation and control during splicing. For micro core fibers, the light guiding region is small, so alignment accuracy is critical. The Type-39 is designed to handle these demands by using core alignment and arc optimization. This helps reduce loss, improve splice strength and support consistent results across different fiber batches. It is useful when standard splice modes do not provide sufficient control.

Core Alignment Process

The splicing process begins with fiber preparation. Coatings are removed, fibers are cleaned and cleaved to a precise angle. The fibers are then loaded into the splicer, where the core alignment system positions them. The arc melts the fiber ends and fuses them together. The Type-39 monitors the process and provides splice loss estimates. This workflow helps technicians make informed decisions and maintain quality across many splices.

Arc Control and Calibration

Arc conditions can change with electrode wear, humidity, temperature and altitude. The Type-39 includes calibration functions to compensate for these variables. Automatic arc calibration helps maintain stable fusion energy. This is important for low loss splicing and for avoiding weak joints. Technicians can also select different arc programs for different fiber types and environmental conditions.

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. The unit 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.

Why Choose the Type-39

The Type-39 is chosen for its precision and its ability to support micro core fiber splicing. It offers a controlled process for demanding fiber types and helps teams achieve low loss joints. For networks where splice quality directly affects performance, the Type-39 provides a dependable core alignment solution.

Conclusion

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