摘要： A preform for a polarization retaining optical fiber is produced by making at least two bores symmetrically around a center axis of a preform comprising a core part and a cladding part which surrounds the core part, decreasing a diameter of one end of each bore, or connecting a glass tube to one end of the preform, the glass tube having a part with a smaller inner diameter near its end which is connected to the preform, inserting a first glass rod, a stressing member and a second glass rod in this order from the other end of each bore or from an end of each bore which is remote from the connected glass tube, contacting the first glass rod to the diameter-decreased end of each bore or to the part with a smaller inner diameter of the glass tube, and heating and fusing the second glass rod to the preform.
