FIELD: optics.
SUBSTANCE: invention relates to binder fibre for fibre-optic unit. Binder fibre for fibre-optic unit comprises flat colour composite fiber such as islands at sea, which contains a component of the sea of flat colour composite fibres of "island in sea", having a melting onset temperature of 100 °C or higher and peak of melting temperature from 120 to 150 °C. Besides, flat colour composite fibre of type "island in sea" has width from 0.5 to 3.0 mm and thickness of 0.15 mm or less. Note here that flat colour composite fibre of type "island in sea" has degree of thermal shrinkage of 1.0 % or less after heating at 100 °C for 3 hours.
EFFECT: technical result – preservation of core shape of the optical fibre and the absence of adhesion with adjacent binding fibres or cores of the optical fibre.
