Description
Loose Tube / Gel-Free / Steel Tape Armored
Single Jacket Single Armored Optical Fiber Cable
Lexington Ames All Dry LA-LT-041 series is ideal for FTTH projects where cables are direct buried or installed in a conduit. The LA-LT-041, Single Mode, 9/125, G.652.D is manufactured with GR-20 certified glass. Available in fiber counts from 12 to 576, the cable is sold in a reel of 14,000 to 20,000 feet.
The Polypropylene loose tube, the Corrugated Steel Tape Armoring, and the Medium Density Polyethylene jacket provide flexibility in handling yet solid protection of the core glasses from UV, rodents, and other greater outside forces.
Standards and Certifications
ITU-T G.650, G.652.D. IEC 60793, 60794. RUS 7 CFR 1755. ISO 9001, 14001, OHSAS 18001. TIA-598-D. GR-20 (glass)
Construction
The cable core consists of color coded fibers, dry water swellable material, color coded loose tubes, PE filler (if necessary), SZ-stranded around the FRP central strength member with water blocking yarn(s).
The cable structure is completed by the application of a core wrapping tape, auxiliary strength member if necessary, which with the core, and the corrugated steel tape armoring are covered by an outer MDPE jacket.
