Abstract

Abstract The invention concerns an optical cable with continuous accessibility, comprising a closed protective sheath surrounding a cavity having in cross section two substantially perpendicular axes intersecting at the center of the cavity, and at least two optical fibers optionally organized in at least two modules and arranged such that they occupy the greater part of the cavity in the direction of the long axis but that they allow a clearance in the cavity in the direction of the shorter axis of the cavity.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 103 words
An optical cable having optical fibers which can be accessed anywhere along the cable, comprising: a closed protective sheath surrounding a cavity having in cross section two substantially perpendicular axes intersecting at the center of the cavity, each axis defining a width of the cavity, one width being wider than the other shorter width; and at least two optical fibers positioned lengthwise in the cable and arranged such that they occupy the greater part of the cavity in the direction of the wide width but that they allow a clearance in the cavity in the direction of the shorter width of the cavity.
Claim 2
Dependent Claim 103 words
An optical cable having optical fibers which can be accessed anywhere along the cable, comprising: a closed protective sheath surrounding a cavity having in cross section two substantially perpendicular axes intersecting at the center of the cavity, each axis defining a width of the cavity, one width being wider than the other shorter width; and at least two optical fibers positioned lengthwise in the cable and arranged such that they occupy the greater part of the cavity in the direction of the wide width but that they allow a clearance in the cavity in the direction of the shorter width of the cavity.
Claim 3
Dependent Claim 31 words
The cable as claimed in claim 1 , wherein the fibers are organized in at least two optical modules each one comprising at least one fiber surrounded by a thin film.
Claim 4
Dependent Claim 25 words
The cable as claimed in claim 1 , wherein the cavity has a shape selected in the group consisting of circular, oval and ovalized shapes.
Claim 5
Dependent Claim 15 words
The cable as claimed in claim 3 , wherein the cavity has an ovalized shape.
Claim 6
Dependent Claim 25 words
The cable as claimed in claim 1 , wherein the sheath has a shape selected in the group consisting of circular, oval and ovalized shapes.
Claim 7
Dependent Claim 15 words
The cable as claimed in claim 5 , wherein the sheath has an ovalized shape.
Claim 8
Dependent Claim 23 words
The cable as claimed in claim 5 , wherein a wide width of the sheath coincides with the wide width of the cavity.
Claim 9
Dependent Claim 15 words
The cable as claimed in claim 1 , comprising further a jacket around the sheath.
Claim 10
Dependent Claim 17 words
The cable as claimed in claim 1 , wherein the sheath has at least one colored thread.
Claim 11
Dependent Claim 16 words

Claim 12
Dependent Claim 15 words
The cable as claimed in claim 10 , wherein at least one initiator is colored.
Claim 13
Dependent Claim 17 words
The cable as claimed in claim 1 , wherein the sheath has a region of lower thickness.
Claim 14
Dependent Claim 17 words
The cable as claimed in claim 8 , wherein the jacket has at least one colored thread.
Claim 15
Dependent Claim 16 words
The cable as claimed in claim 8 , wherein the jacket has at least one initiator.
Claim 16
Dependent Claim 15 words
The cable as claimed in claim 14 , wherein at least one initiator is colored.
Claim 17
Dependent Claim 17 words
The cable as claimed in claim 8 , wherein the jacket has a region of lower thickness.
