Approx. 8 seconds (Auto Mode)

Splice & Heat cycles*5Approx. 230 cycles
Splice programMaximum 300 splice programs can be selected and customized.
Splice data storage10,000 splices
Splice image capture200 splices
Fiber Alignment methodCoreAligns the left and right fibers by the center of their cores.

The alignment method mainly for BIF. It is used in splicing

optical fiber with complicated core profiles.

DiameterAligns the left and right fibers by their outer diameter.
AIASThe axis is moved beforehand. AIAS is effective to splicing of fiber with high eccentricity.

“Attenuation”. Fibers are spliced by shifting the centers of the left and right fiber cores to achieve intentional high splice

*1 Cladding diameters, except φ125μm, are applicable only for splicing in room temperature.

*2 Fiber holders appropriate for the fiber coating and fiber count are required.

*3 These fiber holders cannot be used with loose tube cable which optical fiber is free to move about in.

*4 With Sumitomo identical fibers (in room temperature). Measured by cut-back method relevant to ITU-T and IEC standards.

*5 Splice & Heat cycles may vary depending on the battery status and the operating environment.

*6 The 40mm protection sleeves can be used only if the cleave length is less than 10mm. Do not use the 40mm protection sleeves for fibers with more than φ250μm coatings.

*7 With Sumitomo protection sleeve FPS-61-2.6, Coating diameter φ250μm (in room temperature, powered with AC adapter, DC output port not in use)

*8 The projection parts are excluded.

*9 Confirms the battery operation in tests carried out by Sumitomo. Does not guarantee that the product is free of faults or damage.
