摘要：A polarization-maintaining optical fiber which exhibits an excellent polarization-maintaining performance and significantly low splice loss when spliced with a
polarization-maintaining optical fiber having a cladding 125 μm in diameter even if the
polarization-maintaining optical fiber has a small-diameter cladding of about 80 μm. The polarization-maintaining optical fiber includes a core, a pair of stress-applying parts provided radially outwardly with respect to the core, and a cladding which surrounds the core and the stress-applying parts. With a diameter D of the stress-applying parts between 21 μm and 32 μm, a distance R between the stress-applying parts between 6 μm and 17 μm, and a relative refractive index difference Δ between 0.3% to 0.5%, a sufficiently large mode field diameter (MFD) is obtained; thus splice loss can be reduced.
