Summary: | Disclosed is a small-diameter polarization maintaining optical fibre, which relates to the field of special optical fibres. The small-diameter polarization maintaining optical fibre comprises a quartz optical fibre (5); the periphery thereof is provided with an inner coating (6) and an outer coating (8); the interior of the quartz optical fibre (5) is provided with an optical fibre core layer (1) and a quartz cladding (2); two stress zones (4) are arranged between the optical fibre core layer (1) and the quartz cladding (2); a buffer coating (7) is arranged between the inner coating (6) and the outer coating (8); the periphery of each stress zone (4) is provided with a buffer layer (3) which is concentric with the stress zone (4); when a working wavelength of a small-diameter polarization maintaining optical fibre is 1310 nm, the attenuation thereof reaches less than 0.5 dB/km, and the crosstalk reaches -35 dB/km; and when the working wavelength of the small-diameter polarization maintaining optical fibre is |
