HexaCore Optical Ground Wire (OPGW)

AFL HexaCore Optical Ground Wire cable utilizes fiber-bearing stainless steel tubes stranded alongside aluminum clad steel and/or aluminum alloy wires to create a multi-layer cable design suitable for a variety of environmental and geographical conditions. HexaCore OPGW was developed in response to the demand for higher fiber counts, specifically those greater than 96. For traditional OPGW designs, as the fiber count increased, so too did the cable diameter and weight. However, the advent of placing optical fibers into small diameter stainless steel tubes has allowed for smaller cable sizes with higher fiber counts, thereby furthering the expansion of OPGW into even more applications.

AlumaCore Optical Ground Wire (OPGW)

AFL AlumaCore Optical Ground Wire is preferred for its central aluminum pipe and color-coded fiber optic buffer tubes which simplify the splicing process while providing optimum fiber protection as well as long term product reliability.
The cable design is constructed of a fiber optic core (with multiple sub-units depending on the fiber count) encased in a hermetically sealed hardened aluminum pipe with a covering of one or more layers of steel and/or alloy wires. Installation is very similar to the process used to install conductors, although care must be taken to use the proper sheave or pulley sizes so as not to cause damage or crush the cable. After installation, when the cable is ready to be spliced, the wires are cut away exposing the central aluminum pipe which can easily be ring-cut with a pipe cutting tool. The color-coded sub-units are preferred by most users because they make splice box preparation very simple.
Additionally, AlumaCore OPGW is the ideal solution for those customers looking to isolate or sectionalize their OPGW in an effort to minimize line losses. Ask us more about this unique application for more details.

CentraCore Optical Ground Wire

AFL CentraCore Optical Ground Wire is preferred for its compact size and ability to house up to 72 fibers in a diameter starting at only 12mm. Its small profile offers an exceptional solution to the diameter and weight concerns on many of today’s overloaded transmission towers where an existing shield wire needs to be replaced with an OPGW cable. With the fiber-bearing stainless steel tube securely protected in a hardened aluminum pipe then covered with a layer(s) of aluminum clad steel and/or alloy wires, this condensed design offers a more robust configuration than those options with only a bare stainless steel tube covered by wires.
