STL is committed to creating a world with next-generation technologies that transform everyday living.
Single Jacket Toneable Flat OFC
STL DROP-LITE Flat Drop Dielectric/Toneable Fiber Optic Cable offers ease of installation in an easy-access, single-tube design. The toneable version adds a 24 AWG conductor that provides underground location tracing and is attached by a web for easy tear-away separation from the cable—the most popular option for underground and multipurpose installation.
Single Jacket Flat OFC
STL DROP-LITE Flat Drop Dielectric Fiber Optic Cable offers ease of installation in an easy-access, single-tube design. This cable has optical fibers presented in a tube filled with a thixotropic gel and enclosed in a thermoplastic sheath. The cable has two embedded strength members to avoid buckling. The dielectric version eliminates any bonding and grounding requirements.
Dielectric Single Jacket Microduct OFC
STL Micro-LITE Multitube Single Jacket Fiber Optic Cables are typically used in micro duct or aerial drop installation applications. This cable is a stranded micro-loose-tube cable with optical fiber placed inside robust buffer tubes stranded around a reinforced plastic (FRP) central strength member. In addition to optical fibers, the buffer tube contains water blocking gel to prevent water ingress in the cable.
Loose Tube Single Armor Double Jacket
STL ARMOR-LITE Multitube Double Jacket Steel Tape Armored Cables are suitable for direct burial as well as for duct applications. A corrugated steel tape armor surrounds the cable core with thermoplastic jacket placed over the armor layer making the cable robust and installation friendly.
Loose Tube Single Jacket Armored OFC
STL ARMOR-LITE Gel Free Multitube Single Jacket Steel Tape Armored Cables are suitable for direct burial as well as for duct applications. A Corrugated Steel Tape armor surrounds the cable core with a thermoplastic jacket placed over the armor layer making the cable robust and installation friendly.
Loose Tube Dielectric Single Jacket OFC
STL DUCT-LITE Gel-Free Multitube Fiber Optic Cables are suitable for duct applications. DUCT–LITE comes with gel-free technology, the buffer tubes contain water-swellable yarns, and the cable core is surrounded with water-swellable tape to prevent water ingress in the cable. The cable core is surrounded with thermoplastic sheath making the cable robust and installation friendly.
Multitube Gel Free Single Jacket Armored
STL RIBBON-LITE Multitube Steel Tape Armored Cable combines robust performance for duct installations with the productivity of high-count mass fusion splicing. Twelve optical fibers are arranged into ribbon units by placing the fibers in a flat array of color-coded fibers bonded together by a UV-curable acrylate matrix. Corrugated steel tape armor surrounds the cable core with a thermoplastic jacket placed over the armor layer, making the cable robust and installation friendly.
Dielectric Multitube Gel Free Single Jacket
STL RIBBON-LITE Multitube Single Jacket Cable combines robust performance for duct installations with the productivity of high-count mass fusion splicing. Twelve optical fibers are arranged into ribbon units by placing the fibers in a flat array of color-coded fibers bonded together by a UV-curable acrylate matrix. This cable offers an outstanding solution for demanding high-growth, high-bandwidth communications applications like data centers, equipment connections within cabinets, and outside plant applications.
Unitube Gel Free Single Jacket Armored
STL RIBBON-LITE Unitube Single Jacket Steel Tape Armored Cable combines robust performance for duct as well as direct installations with the productivity of high-count mass fusion splicing. A corrugated steel tape armor surrounds the buffer tube, sheathed in a thermoplastic jacket with embedded steel strength members placed diagonally opposite the armor layer, making the cable robust and installation friendly.
Dielectric Unitube Gel Free Single Jacket
STL RIBBON-LITE Unitube Single Jacket Cable combines robust performance for high-count mass fusion splicing. The optical fibers are arranged into ribbon units by placing the fibers in a flat array of color-coded fibers bonded together by a UV-curable acrylate matrix.
