Abstract
Abstract A splice cassette housing for optical waveguides has to be brought from an installation position, e.g. a socket-type housing, to a splice position. The incoming and outgoing optical waveguide cables fed with known splice cassette housings along the longitudinal sidewalls are disadvantageous for the free mobility of the splice cassette housing. In order to achieve a high degree of freedom in the mobility of the splice cassette housing, the incoming and outgoing optical waveguide cables 8 and 9 are usually fed separately from each other to the splice cassette housing in a common axis within a flexible hose. Further, a groove-type guide channel 11 in the shape of a member "9" is provided in the bottom 6 of the housing for a change in direction of one of the optical waveguide cables by 180°, in order to be able to feed the individual optical waveguides again from opposed directions to the splice position. The splice cassette housing is suitable for applications especially in cable-terminal boxes, but also in cable distributors and the like for glass-fiber cables.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
A splice cassette housing for optical waveguides, defining a housing compartment having a bottom with an opening for a flexible optical waveguide cable hose and including a groove extending along said bottom defining an optical waveguide receiving channel which extends through a curve within said housing compartment and which extends back upon itself and provides a guide groove for at least one of said optical waveguides which is effected to change the direction thereof by 180°, said optical wave guides having a plurality of separate reserve lengths, and a plurality of pockets in said compartment arranged one above the other and containing respective lengths of said wave guides.
Claim 2
Dependent Claim
108 words
A splice cassette housing for optical waveguides, defining a housing compartment having a bottom with an opening for a flexible optical waveguide cable hose and including a groove extending along said bottom defining an optical waveguide receiving channel which extends through a curve within said housing compartment and which extends back upon itself and provides a guide groove for at least one of said optical waveguides which is effected to change the direction thereof by 180°, said optical wave guides having a plurality of separate reserve lengths, and a plurality of pockets in said compartment arranged one above the other and containing respective lengths of said wave guides.
Claim 3
Dependent Claim
36 words
A splice cassette housing according to claim 1, wherein said groove for guiding an optical waveguide cable is substantially in the shape of a numeral 9 and is arranged on the bottom of said housing compartment.
Claim 4
Dependent Claim
51 words
A splice cassette housing according to claim 1, wherein said compartment is substantially box-shaped and includes side walls, end walls and a top cover, said housing compartment having an opening in said bottom for the passage of said flexible hose, said guide channel being arranged adjacent one of said side walls.
Claim 5
Dependent Claim
47 words
A housing according to claim 3, including a flexible hose connected into said compartment, said flexible hose carrying a plurality of said flexible optical waveguide cables and defining a common axis therefor and being of a construction and material so as to define a minimum bending radius.
Claim 6
Dependent Claim
30 words
A housing according to claim 4, wherein said reserve lengths provide splicing portions and said pockets providing means in said compartment for arranging said splicing portions one above the other.
Claim 7
Dependent Claim
34 words
A splice cassette housing according to claim 5, wherein said pockets are open along a longitudinal side on each side and including a tongue extending over and closing at least one of said sides.
Claim 8
Dependent Claim
35 words
A splice cassette housing, according to claim 1, including means for fixing said pockets to at least one side of said compartment leaving the opposite side free, said pockets being arranged in a fan-type manner.
Claim 9
Dependent Claim
16 words
A splice cassette housing according to claim 7, wherein said pockets are formed by plastic foils.
Claim 10
Dependent Claim
140 words
A splice cassette housing comprising the housing including a box-shaped lower portion defining a compartment having a bottom, side and end walls and a cover closing the top of said lower portion, flexible optical waveguide cable hose holding a plurality of cables extending into one side of said housing and into said compartment, means for clamping said cable hose in said compartment, said compartment having a groove defining a guide channel for at least one optical waveguide cable extending around in a curve on the bottom of said compartment and providing a guide through 180° for said optical waveguide cable and back to said flexible hose, at least one of said optical waveguide cables having a splicing portion and including a plurality of receiving pockets for said splicing portions in said compartment arranged in a stack one above the other.
Claim 11
Dependent Claim
140 words
A splice cassette housing comprising the housing including a box-shaped lower portion defining a compartment having a bottom, side and end walls and a cover closing the top of said lower portion, flexible optical waveguide cable hose holding a plurality of cables extending into one side of said housing and into said compartment, means for clamping said cable hose in said compartment, said compartment having a groove defining a guide channel for at least one optical waveguide cable extending around in a curve on the bottom of said compartment and providing a guide through 180° for said optical waveguide cable and back to said flexible hose, at least one of said optical waveguide cables having a splicing portion and including a plurality of receiving pockets for said splicing portions in said compartment arranged in a stack one above the other.
