LG lightguide cables will provide excellent transmission performance and protection of the fibers in a variety of field environments. These aerial optical cables are designed for circumstances where underground cables would be unsuitable or less economical than aerial cables.
* When the terrain is unsuitable for underground cable
* Where a permanent underground cable cannot be satisfactorily established
* Where short term provision for growth is necessary
* Where additional circuits are required on aerial routes which are heavily loaded
* Single mode or multimode fiber
* Easy to install
* Self-support design
* Standard fiber counts : 2-144
