LG lightguide cables will provide excellent transmission performance and protection of the fibers in a variety of field environments. These cables are designed for installation on new or existing pole lines where existing messenger wire cannot be used and use in areas near high-voltage lines.
* Areas with lightning risks
* Vicinities of power line plants
* Aerial installation
* All dielectric self supporting construction
* Round construction for minimum wind drag and ice build up
* Increase span length capacity
* Standard fiber counts : 2-144
