Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
44 words
An optical fibre transmission system characterised by an optical fibre (3) which radiates power along its length, means for coupling information (1) to be transmitted into the fibre (2) and means for detecting (2,2 1 ) the information as radiated from the fibre (3).
Claim 2
Dependent Claim
44 words
An optical fibre transmission system characterised by an optical fibre (3) which radiates power along its length, means for coupling information (1) to be transmitted into the fibre (2) and means for detecting (2,2 1 ) the information as radiated from the fibre (3).
Claim 3
Dependent Claim
71 words
An optical fibre transmission system as claimed in claim 1 and for transmitting information in an office, or control room, from a main computer (1), characterised in that the main computer (1) is coupled to the optical fibre and in that the detecting means (2,2 1 ) is disposed on mobile or fixed terminals located within the office, or control room, and within a predetermined radial distance from the fibre (3).
Claim 4
Dependent Claim
66 words
An optical fibre transmission system as claimed in claim 2 characterised in that other terminals (4,5,6) within the office, or control room, receive information as radiated by the optical fibre (3) and are coupled to the optical fibre (3) via respective optical fibre links and bi-directional couplers whereby to supply information to one another (4,5,6), passive mobile terminals (2,2 1 ) or the main computer (1).
Claim 5
Dependent Claim
35 words
An optical fibre transmission system as claimed in any one of claims 1 to 3, characterised in that the radiating optical fibre (3) comprises a single mode fibre operating at a V value below 1.5.
Claim 6
Dependent Claim
28 words
An optical fibre transmission system as claimed in any one of claims 1 to 3, characterised in that the radiating optical fibre (3) comprises a deeply depressed fibre.
Claim 7
Dependent Claim
55 words
An optical fibre transmission system as claimed in any one of claims 1 to 3, characterised in that the radiating optical fibre (3) is a single mode fibre operating at a V value of 1.5 or below and optically pumped whereby to achieve leaky radiation at the first Stokes shift away from the transmitted wavelength.
