PROBLEM TO BE SOLVED: To provide a polarization maintaining optical fiber and an optical connector that reduce cracking of a stress-imparted part in end surface working of the polarization maintaining optical fiber, make small recess of the stress-imparted part in high-temperature, high-humidity environment, minimize projection of the stress-imparted part on an optical fiber end surface, and never impede PC connection of the optical connector. SOLUTION: The polarization maintaining optical fiber 1 has the stress-imparted part 4, to which B<SB>2</SB>O<SB>3</SB>is added, at a clad part at the outer periphery of a core part 2 across the core part 2, and the quantity of projection of the stress-imparted part 4 from the optical fiber end surface in specified high-temperature, high-humidity environment is≤0.1μm. Further, the mean concentration of B<SB>2</SB>O<SB>3</SB>of the stress-imparted part 4 is 14 to 16 wt%. COPYRIGHT: (C)2004,JPO&NCIPI |
