摘要
We have developed a polarization-maintaining fiber with wide temperature resistance and low bending loss. Attenuation, polarization crosstalk, and bending loss at 1550 nm of the fiber are 0.88 dB/km, -24 dB/100m, 1/100 as large as those of conventional one (bending diameter = 20 mm, 10 turns), respectively. Besides, the polarization crosstalk is less than -24 dB/100m at a temperature in the range of -60 to + 300 degrees C. As a result this fiber can be used over a wide range of temperature.
