Abstract :
The transmission loss at low temperature of an optical fibre tightly jacketed with a new low-linear-expansion-coefficient plastic, thermotropic liquid-crystal polymer, is reported. The new type of tight-jacket fibre is free from microbending losses due to jacket contraction when exposed to heat cycles from ¿70 to 80°C.
