FIELD: physics.
SUBSTANCE: fibre-optic connector has first and second half couplings for sealing first and second sections of optical fibre on whose butt ends there are first and second pairs of step-up and step-down optical multi-layer transformers. There is an air gap between the outer layers of the first and second pairs of optical multi-layer transformers. Layers of the first and second pairs of optical multi-layer transformers are made from materials with different refraction indices and are measured from outer layers of step-down transformers of the first and second pairs of optical multi-layer transformers adjacent to the air gap towards the butt ends joined to optical fibre sections. Thickness of each layer is equal to a quarter of the medium wave Xo of the signal transmitted over the optical fibre and the number of layers is selected based on conditions given in the formula of invention.
EFFECT: lower level of power loss arising due to insufficiently close contact or welded joint at the position of the joint and wider range of apparatus for this purpose.
