Abstract
An apparatus for supporting and maintaining slack of fiber optic cable or the like in an aerial installation comprises an elongate channel member having an arcuate section and a plurality of linear sections for receiving the slack and means for securing the apparatus to a messenger cable support structure. Methods for supporting and maintaining the slack in two preferred embodiments are also disclosed.
Claims22
In an aerial installation of fiber optic cable, wherein said fiber optic cable has a minimum bending radius and is suspended along its length at spaced-apart intervals by a support structure, an apparatus comprising:
- maintenance means for receiving a predetermined section of slack of said suspended fiber optical cable, said predetermined section of slack having a length substantially greater than the height at which said section is suspended on said support structure, and for maintaining said slack at a radius no less than the minimum bending radius of said fiber optic cable;
- and
- attachment means connected to said maintenance means for securing said apparatus at selected locations of said support structure.
In an aerial installation of fiber optic cable, wherein aid fiber optic cable has a minimum bending radius and is suspended along its length at spaced-apart intervals by a support structure including a messenger cable, an apparatus comprising:
- an integrally-formed elongate member, said elongate member having a channel dimensioned to receive a predetermined section of slack of said suspended fiber optic cable, said predetermined section of slack having a length substantially greater than the height at which said section is suspended on said support structure;
- and
- a lip clamp connected to said elongate member for securing said apparatus to said messenger cable.
In an aerial installation of fiber optic cable, said fiber optic cable having an originating end and a terminating end and wherein said fiber optic cable has a minimum bending radius and is suspended along its length at spaced-apart intervals by a support structure including a messenger cable, and an apparatus for maintaining a predetermined section of slack of said suspended fiber optic cable, aid predetermined section of slack having a length substantially greater than the height at which said section is suspended on said support structure, said apparatus having an arcuate section and upper and lower linear sections, a method of maintaining said predetermined section of slack, comprising the steps of:
- guiding a first fiber optic cable to be spliced, successively, through said upper linear section, said arcuate section, and said lower linear section of said apparatus;
- splicing said first fiber optic cable to a second fiber optic cable at a splice enclosure;
- securing said splice enclosure to said messenger cable;
- attaching said apparatus on said messenger cable at a predetermined distance from said splice enclosure and orienting the arcuate section of said apparatus toward the direction of the terminating end of the support structure;
- and
- securing said apparatus to said messenger cable.
In an aerial installation of fiber optic cable, said fiber optic cable having an originating end and a terminating end and wherein cable is suspended along its length at spaced-apart intervals by a support structure including a messenger cable, and an apparatus for maintaining a predetermined section of slack of said suspended fiber optic cable, said predetermined section of slack having a length substantially greater than the height at which said section is suspended on said support structure, said apparatus having an arcuate section and upper and lower linear sections, a method of maintaining said predetermined section of slack, comprising the steps of:
- guiding said first fiber optic cable to be spliced, successively, through said upper linear section, said arcuate section, and said lower linear section of said apparatus;
- splicing said first fiber optic cable to said second fiber optic cable, at a splice enclosure;
- securing said splicing enclosure to said messenger cable;
- attaching said apparatus on said messenger cable at a predetermined distance from said splice enclosure and orienting the arcuate section of said apparatus toward the direction of the terminating end of the support structure;
- and
- securing said apparatus to said messenger cable.
In an aerial installation of fiber optic cable, wherein said fiber optic cable is suspended along its length at spaced-apart intervals by a support structure and said length of fiber optic cable includes a predetermined section of slack, said predetermined section of slack having a length substantially greater than the height at which said section is suspended on said support structure, a method of maintaining said predetermined section of slack, comprising the steps of:
- attaching an apparatus for maintaining said predetermined section of slack to said fiber optic cable;
- and
- securing said apparatus to said support structure.
In an aerial installation of fiber optic cable, wherein said fiber optic cable is suspended along its length at spaced-apart intervals by a support structure and said length of fiber optic cable includes a predetermined section of slack, said predetermined section of slack having a length substantially greater than the height at which said section is suspended on said support structure, comprising the steps of:
- attaching first and second apparatus for maintaining said predetermined section of slack to said fiber optic cable;
- and
- securing said first and second apparatus to said support structure.
In an aerial installation of spliced fiber optic cables, wherein said fiber optic cables are spliced at a splice enclosure and suspended along its length at spaced-apart intervals by a support structure, and said fiber optic cable includes a predetermined section of slack, said predetermined section of slack having a length substantially greater than the height at which said section is suspended on said support structure, a method of maintaining said predetermined section of slack comprising:
- attaching said predetermined section of slack to an apparatus for maintaining said predetermined section of slack;
- and
- securing said apparatus to said support structure.
