Enhancing the precision of fiber optic splicing, these pitch conversion holders are crafted for expert alignment and reliability during use. Designed specifically for 200 µm loose fibers, this pair of holders effectively supports the arrangement of up to 12 fibers, making it an essential component for forming temporary ribbons that facilitate mass fusion splicing. Compatibility with the RT-02 ribbonizing tool and Fujikura fusion splicing equipment, including popular models like the FSM-70R+ and 90R, underscores their practical application in professional settings. With a focus on repeated use, these holders are vital for anyone looking to streamline their splicing processes while ensuring accuracy and efficiency.
