Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
An electro-optical termination including an array of electro-optical converter devices mounted within a hermetically sealed enclosure; a plurality of individual optical fibres, the ends of which are held in a fixed position relative to each other corresponding to said array and which terminate in a common plane; a rigid fibre optical facepiate mounted with one of its major faces adjacent to said array and the other of its major faces being adjacent to said plane with the faceplate forming part of the wall of said hermetically sealed enclosure.
Claim 2
Dependent Claim
88 words
An electro-optical termination including an array of electro-optical converter devices mounted within a hermetically sealed enclosure; a plurality of individual optical fibres, the ends of which are held in a fixed position relative to each other corresponding to said array and which terminate in a common plane; a rigid fibre optical facepiate mounted with one of its major faces adjacent to said array and the other of its major faces being adjacent to said plane with the faceplate forming part of the wall of said hermetically sealed enclosure.
Claim 3
Dependent Claim
19 words
A termination as claimed in claim 1 and wherein the converter devices are arranged in a two dimensional pattern.
Claim 4
Dependent Claim
61 words
A termination as claimed in claim 1 or 2 and wherein the ends of the individual optical fibres are held in position by means of a rigid opaque plate having a major surface which is aligned with the adjacent major face of said faceplate, and the individual optical fibres terminating in apertures which pass through the thickness of the rigid plate.
Claim 5
Dependent Claim
19 words
A termination as claimed in claim 3 and wherein the rigid plate is a metal plate of uniform thickness.
Claim 6
Dependent Claim
27 words
A termination as claimed in claim 3 or 4 and wherein the optical fibres terminate in the plane of said major surface of the rigid opaque plate.
Claim 7
Dependent Claim
49 words
A termination as claimed in claim 3, 4 or 5 and wherein the individual optical fibres are held in position within the metal plate by means of a setable material, which is formed around the fibres at the point where they emerge from the apertures in the metal plate.
Claim 8
Dependent Claim
16 words
A termination as claimed in claim 6 and wherein said setable material is an epoxy resin.
Claim 9
Dependent Claim
29 words
A termination as claimed in any of the preceding claims and wherein the electro-optical converter devices are supported on a base plate which also forms part of said enclosure.
Claim 10
Dependent Claim
27 words
A termination as claimed in claim 8 and wherein said converter devices are mounted on a ceramic substrate which in turn is mounted on said base plate.
Claim 11
Dependent Claim
116 words
A termination as claimed in claim 8 or 9 and wherein a collar is attached to the base plate and extends therefrom to support said faceplate, the collar being of sufficient depth to provide clearance for the height of the electro-optical converter devices and to determine the spacing of the active surface of these devices from the adjacent surface of said faceplate. 1 A termination as claimed in claim 10 and wherein said collar forms part of the envelope of said hermetically sealed enclosure and is sealed in a gas tight manner to the base plate and the faceplate. 1 2. An electro-optical termination substantially as illustrated in and described with reference to the accompanying drawing.
