Basically, this is an addition of connectors to each optical fibre in the cable.
Here we use SC connector with pigtail. It is short, tight-buffered optical fibre with optical SC connector pre‑installed on one end and a length of exposed fibre at the other end.
Termination process is described on the fibre fusion and protection page. The end of a pigtail is being spliced to a single fibre of a multi-fibre trunk.
Thus, splicing of pigtails to each fibre in the trunk splits the multi-fibre cable into separate fibres for connection to the end equipment.
