Sumitomo Type-71C DCM Fusion Splicer

The Sumitomo Type-71C DCM Fusion Splicer is a core alignment fusion splicing system developed for micro core fiber and high precision network work. It is paired with the FC-6RS cleaver to support accurate fiber end preparation. The combination is suitable for technicians who need low splice loss, repeatable arc performance and dependable field operation. The Type-71C is often used in FTTx, metro, backbone and long haul projects where fiber geometry and core alignment are critical.

DCM Splicing Technology

DCM technology supports detailed core monitoring during the splice process. This helps the splicer evaluate fiber alignment and arc conditions more effectively, especially when working with micro core fibers or fibers with challenging geometric characteristics. The system is designed to reduce splice loss and improve consistency across different fiber types. It also helps technicians achieve reliable results when working with small core diameters or specialty fibers.

Micro Core Fiber Support

Micro core fibers are used in applications that require tight bend performance and high density routing. These fibers can demand careful alignment and controlled arc energy. The Type-71C is built to handle such requirements by combining core alignment, arc calibration and optimized splice programs. When paired with proper cleaning and cleaving, it supports stable splices in access, distribution and subscriber networks. It can also be used in specialized environments where standard splice programs may not provide the best result.

FC-6RS Cleaver

The FC-6RS cleaver is a precision field cleaver that produces flat fiber end faces. A consistent cleave angle is important because poor end quality can cause bubbles, high loss or arc instability. The FC-6RS supports single fiber preparation and is designed for durable field use. Its blade position and clamp system help technicians achieve repeatable cleaves. The cleaver complements the Type-71C by preparing fibers before they are loaded into the splicer.

Arc Calibration and Stability

The Type-71C includes automatic arc calibration functions that adjust to environmental changes. Temperature, humidity, altitude and electrode wear can affect arc strength. By calibrating the arc, the splicer helps maintain stable melting and reduces the need for manual adjustments. This is valuable in field work where conditions change during the day. Users can also select splice modes based on fiber type and application needs.

Field Workflow

A typical workflow begins with cable access, fiber routing and coating removal. Fibers are cleaned, cleaved with the FC-6RS and loaded into the splicer. The Type-71C 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 and reduce rework.

Applications

The Type-71C is suitable for FTTx, metro, backbone, long haul, campus and utility networks. It is also useful for micro core fiber projects where bend insensitivity and space saving are important. The splicer supports both new construction and maintenance, including emergency repair where fast and accurate splicing is required.

Durability and Portability

The unit is designed for field transportation with a protective carry case, battery operation and rugged housing. It can be used in cabinets, tents, vehicles and aerial work platforms. The interface provides clear menus and status information. The battery supports extended work sessions, and the compact design helps technicians move between sites efficiently.

Maintenance

Regular maintenance includes cleaning V grooves, clamps, objectives and fiber holders. Electrodes should be replaced according to arc count and splice quality. The FC-6RS cleaver should be cleaned and its blade rotated or replaced when cleave quality declines. Proper storage and handling help extend the life of both the splicer and cleaver.

Conclusion

The Sumitomo Type-71C DCM Fusion Splicer with FC-6RS cleaver is a precision solution for micro core and core alignment splicing. It combines advanced arc control, field durability and accurate fiber preparation. For networks that demand low loss and repeatable results, the Type-71C is a strong technical choice.
