SHINHO S-37 Series Large Diameter Fiber Fusion Splicer for Fiber Laser Repair

Product overview Overview SHINHO S-37 / S-37+ Large Diameter Fiber Fusion Splicer | For Fiber Laser Repair and Specialty Fiber Splicing The SHINHO S-37 Series Large Diameter Fiber Fusion Splicer is designed for splicing specialty optical fibers used in fiber laser repair, manufacturing, research, and high-power optical systems. It supports core alignment, large diameter fibers, and both manual and automatic operation for stable splicing of SM, MM, DS, NZDS, EDF, DCF, and LDF fibers. The S-37 is the recommended choice for most repair customers, offering reliable large diameter fiber splicing at a practical cost. The S-37+ adds rotation alignment, supports larger cladding diameters, and enables active fiber splicing, making it suitable for certain MAX laser repair applications. Due to its higher cost and the fact that many customers do not repair active fiber coils or modules directly, the S-37+ is generally recommended only when rotation alignment or active fiber splicing is required. Special Note: A wire stripper (model X-2006) is included with the purchase of this product; it is adjustable to 250/400μm. Best For S-37: General large diameter fiber splicing for fiber laser repair and service work. Customers repairing common passive and specialty fibers without rotation alignment requirements. S-37+: MAX equipment repair customers who need active fiber splicing capability. Applications requiring rotation alignment and larger cladding diameter fiber support. Research, laboratory, and production environments requiring low splice loss and repeatable arc performance. Key Features Core-to-core alignment for precision splicing. S-37 supports 125-600 um cladding diameter fibers. S-37+ supports 125-680 um cladding diameter fibers. S-37+ includes rotation alignment and can support active fiber splicing. 210-900 um coating diameter range. Typical splice loss: 0.03 dB for SM fiber, 0.02 dB for MM fiber, 0.05 dB for DS and LDF fiber. Return loss better than 60 dB. 40 customizable splicing programs. Manual and automatic splicing modes.

The S-37+ adds rotation alignment, supports larger cladding diameter fibers, and can be used for active fiber splicing. The S-37 is more suitable for most standard large diameter fiber repair needs. Which model is recommended for most customers? The S-37 is generally recommended for most repair customers because it covers common fiber laser repair needs at a more practical cost. When should I choose S-37+? Choose S-37+ when the repair application clearly requires rotation alignment, active fiber splicing, larger cladding diameter support, or selected MAX equipment repair capability.
