    *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.

    *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.
