The precise optical resonators represent a crucial tool for ultra-narrow linewidth lasers frequency stabilisation. They can serve as frequency references for lasers of optical clock systems, optical frequency combs locking, dissemination of precise time and frequencies over optical links, or laser interferometry. The critical properties of these resonators are determined by their design, used materials and environmental conditions where they are operated. This contribution describes the design of the sub-Hz linewidth optical cavity, and it analyses its performance in the optical setup with a frequency-stabilised 1540 nm fibre laser. The cylindrical-shaped Fabry-Perot resonator with optical mirrors and a spacer part made of ceramics with ultra-low thermal expansion coefficient is placed inside the multi-shielded vacuum and thermostated chamber. The optical setup employs the Pound-Drewer-Hall locking technique for the laser locking, and the system’s performance is measured by the H-maser referenced optical comb.
