Claim 5

A bonded strength member comprising a longitudinally extending fiber reinforced plastic core, and a polyethylene jacket enveloping said core and being adhesively bonded thereto by a layer of ethylene acrylic acid extending over substantially the entire peripheral surface of said fiber reinforced plastic core, thereby preventing relative movement between the core and the jacket.

Claim 6

A bonded strength member comprising a longitudinally extending fiber reinforced plastic core, and a polyethylene jacket enveloping said core and being adhesively bonded thereto by a layer of ethylene acrylic acid extending over substantially the entire peripheral surface of said fiber reinforced plastic core, thereby preventing relative movement between the core and the jacket.

Claim 7

A bonded strength member according to claim 4 wherein said polyethylene jacket comprises low density polyethylene and the interfacing surfaces of said core and said jacket are inert.

Claim 8

An optical transmission fiber cable of the type having at least one optical transmission fiber and a supporting messenger attached thereto, said at least one optical transmission fiber comprising a tight buffer layered cable having a longitudinally extending central support member surrounded by a plurality of optical fibers, the improvement comprising a messenger having a fiber reinforced plastic rod, and a polyethylene jacket bonded to said fiber reinforced plastic rod with an adhesive layer of ethylene acrylic acid provided therebetween, thereby preventing relative movement between the messenger rod and polyethylene jacket.

Claim 9

An optical transmission fiber cable of the type having at least one optical transmission fiber and a supporting messenger attached thereto, said at least one optical transmission fiber comprising a tight buffer layered cable having a longitudinally extending central support member surrounded by a plurality of optical fibers, the improvement comprising a messenger having a fiber reinforced plastic rod, and a polyethylene jacket bonded to said fiber reinforced plastic rod with an adhesive layer of ethylene acrylic acid provided therebetween, thereby preventing relative movement between the messenger rod and polyethylene jacket.

Claim 10

An optical transmission fiber cable of the type having at least one optical transmission fiber and a supporting messenger attached thereto, said at least one optical transmission fiber comprising a plurality of generally longitudinally extending loose tubes each containing a plurality of optical transmission fibers, the improvement comprising a messenger having a fiber reinforced plastic rod, and a polyethylene jacket bonded to said fiber reinforced plastic rod with an adhesive layer of ethylene acrylic acid provided therebetween, thereby preventing relative movement between the messenger rod and polyethylene jacket.

Claim 11

An optical transmission fiber cable of the type having at least one optical transmission fiber and a supporting messenger attached thereto, said at least one optical transmission fiber comprising a plurality of generally longitudinally extending loose tubes each containing a plurality of optical transmission fibers, the improvement comprising a messenger having a fiber reinforced plastic rod, and a polyethylene jacket bonded to said fiber reinforced plastic rod with an adhesive layer of ethylene acrylic acid provided therebetween, thereby preventing relative movement between the messenger rod and polyethylene jacket.

Claim 12

An optical transmission fiber cable of the type having at least one optical transmission fiber and a supporting messenger attached thereto, the improvement comprising a messenger having a fiber reinforced plastic rod, and a polyethylene jacket bonded to said fiber reinforced plastic rod with an adhesive layer of ethylene acrylic acid provided therebetween, thereby preventing relative movement between the messenger rod and polyethylene jacket, said polyethylene jacket comprising a first relatively thin pre-coat layer which is bonded to said fiber reinforced plastic rod by said adhesive layer of ethylene acrylic acid, and a second relatively thicker layer of polyethylene which is bonded to said first pre-coat layer of polyethylene.

Claim 13

An optical transmission fiber cable of the type having at least one optical transmission fiber and a supporting messenger attached thereto, the improvement comprising a messenger having a fiber reinforced plastic rod, and a polyethylene jacket bonded to said fiber reinforced plastic rod with an adhesive layer of ethylene acrylic acid provided therebetween, thereby preventing relative movement between the messenger rod and polyethylene jacket, said polyethylene jacket comprising a first relatively thin pre-coat layer which is bonded to said fiber reinforced plastic rod by said adhesive layer of ethylene acrylic acid, and a second relatively thicker layer of polyethylene which is bonded to said first pre-coat layer of polyethylene.

Claim 14

A bonded strength member comprising a longitudinally extending fiber reinforced plastic core, and a polyethylene jacket enveloping said core and being adhesively bonded thereto by a layer of ethylene acrylic acid extending over substantially the entire peripheral surface of said fiber reinforced plastic core, thereby preventing relative movement between the core and the jacket, said polyethylene jacket comprising a relatively thin pre-coat layer which is bonded to said fiber reinforced plastic core by said adhesive layer of ethylene acrylic acid, and a second relatively thicker layer of polyethylene which is bonded to said first pre-coat layer.

Claim 15

A bonded strength member comprising a longitudinally extending fiber reinforced plastic core, and a polyethylene jacket enveloping said core and being adhesively bonded thereto by a layer of ethylene acrylic acid extending over substantially the entire peripheral surface of said fiber reinforced plastic core, thereby preventing relative movement between the core and the jacket, said polyethylene jacket comprising a relatively thin pre-coat layer which is bonded to said fiber reinforced plastic core by said adhesive layer of ethylene acrylic acid, and a second relatively thicker layer of polyethylene which is bonded to said first pre-coat layer.
