During attenuation test, the optical fibre with polyimide coating shall be wound with near zero tension on an optical fibre spool greater than 36 cm in diameter.
Optical fibres with different core diameters (e.g. 100μm, 200μm, and 300μm) can be equipped with a high-temperature resistant coating according to customer requirements.
