Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
263 words
An assembly capable of enclosing and sealing at least one optical fibre cable, which comprises: a hollow article comprising a base plate (1) and a hollow cover (2) disengageable from the base plate, the base plate having at least two mutually adjacent outlets capable of receiving respective optical fibre cables; the assembly having at least one optical fibre organizer (5) housed within the article for storing a plurality of optical fibres in a path from one of the outlets (3) to another of the outlets (3), said path having a minimum radius of curvature no smaller than the minimum bend radius of said optical fibres; and first means for connecting the base plate (1) to the hollow cover (2) and second means (7,9) for connecting the at least one optical fibre organizer to the base plate (1) such that when the first and second means are so connected the optical fibres are stored in at least one storage plane and such that when the first means is disconnected the hollow cover (2) is removable from the base plate (1) by being moved along a direction which is substantially parallel to the storage plane, substantially parallel to each outlet direction at the base plate and substantially perpendicular to the base plate and in which the base plate has means for electrical and/or mechanical connection to a cable outer screen and/or strength member and the organizer comprises at least one optical fiber tray in which the trays additionally comprise a splice holder capable of locating a fiber splice on a second portion of the tray.
Claim 2
Dependent Claim
