Suitable for connecting home butterfly cable. Utilizes mature V-groove butt joint technology, applicable to multimode optical fiber connections. Free of fixture design, operation time is under a minute. For fiber optic buttingjoining optical fiber to optical fiber or optical fiber to pigtailthis is employed to create the joint. (Butting optical fiber pigtail refers to linking the fiber core of a pigtail to a butt fiber, replacing the former method. ) This is a cold connection device, also known as an optical fiber cold splice
