Arrangement for branching a telecommunications cable containing several stranded elements with optical fibers
First Claim
1. An arrangement for connecting to a main cable containing several stranded elements, each with a plurality of optical fibers therin, comprising:
- (a) a housing;
(b) at least two splice cassettes in the housing; and
(c) a branch-off cable entering the housing in a fluid tight manner and having at least two optical fibers adapted for splicing to the optical fibers of the main cable to create a branched area to be protected to a sleeve, the sleeve for the branched area is buried undergound, each optical fiber protected by a separate pair of tubes made of polymeric material, a portion of each optical fiber not located within its pair of tubes and being stored in a respective one of the at least two splice cassettes in the housing thereby acting as excess length being adapted to be connected to a subscriber connection cable, wherein the branch-off cable and the housing with the cassettes comprise a prefabricated unit.

Abstract
In an arrangement for producing a branch in a telecommunications cable (1) containing several stranded elements with optical fibers, at least one stranded element is cut, the optical fibers of the stranded element are spliced to the optical fibers of a branch line (2), and the branched area is protected with a sleeve (3). The branch line (2) comprises a number of optical fibers, each of which is loosely arranged by itself in a small plastic tube (10). A predetermined length of the tube (10) is removed from approximately the middle of the optical fiber elements, and each optical fiber (13) from which the tube (10) has been removed is stored in a cassette (12). The cassettes (12) are stored in a container (5). The sleeve housing (4) is stored in a container (5). The sleeve housing (4) with the cassettes (12) and the branch line (2) with the optical fibers (13) located in the tube (10) are a unit which is prefabricated at the factory.

17. An arrangement for branching a telecommunications cable containing several stranded elements, each with a plurality of optical fibers therein, comprising:
- at least one stranded element being cut, the optical fibers of the stranded element are spliced to optical fibers of a branch line to create a branched area which is protected with a sleeve, each optical fiber of the branch line is arranged in a pair of casings so that a portion of the optical fiber is not contained therein, the portion of the optical fiber is stored in a cassette, the cassettes are located in a sleeve housing which can be opened, and the sleeve housing is located in a container, wherein the container includes;
a) upper and lower holders provided on opposite sides of an inside wall of the container and at different levels;
b) the sleeve housing attached to the lower holder by a bottom part; and
c) the sleeve housing is secured with a rod, one end of which is screwed to the holder. - View Dependent Claims (18, 19, 20, 21, 22, 23)
