摘要:
An optical attenuator comprising first and second coaxial optical fibres (2,3) which are optically coupled to each other with a gap (ℓ) between their adjacent end faces (22,31) characterised in that each of the adjacent end faces (22,31) is disposed obliquely to the axis of the optical fibres (2,3).
摘要:
A ferrule (1) is held to a ferrule-holding jig (2) such that the ferrule (1) is tilted at an angle of Θ to the axis of rotation of a polishing platen (3). The ferrule (1) is pressed against a polishing sheet (5) lying on the polishing platen (3) via a resilient body (4). The polishing platen (3) is so tilted that the angle between the axis of the ferrule and the normal to the polishing platen increases by Δ from Θ.
摘要:
An optical isolator has a faraday rotator (5) driven by magnets (11). An orientation of magnetization (15) of the magnets (11)is approximately vertical to the optical axis (13) of the optical isolator.
