Is it okay to use wire to pull fiber optic cables across power poles
Most fiber optic cable installations are designed around controlled pulling. I'm using to pulling electrical wire and even ethernet through conduit, so I'm ready with a nice free-spinning setup for the new fiber cable to make sure it feeds smoothly into the 1" conduit. It happens during installation, when excessive pulling force, tight bends. General Consideration: It is generally not recommended to run fiber optic cables in the same conduit as electrical power cables. This is due to several potential risks and complications that can arise from such an arrangement. Every time an optical fiber cable is cut in the field, small invisible glass shards can be produced. Once this happens, our bodies have no way of removing them.

What are the types of heterogeneous power optical cables
There are two main types of material used for optical fibers: glass and plastic. They offer widely different characteristics and find uses in very different applications.OverviewA fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an but containing one or more that are used to carry light. The optical fiber elements are typically individually. Optical fiber consists of a and a layer, selected for due to the difference in the between the two. In practical fibers, the cladding is usually coated wit. In September 2012, NTT Japan demonstrated a single fiber cable that was able to transfer 1 per second (10 bits/s) over a distance of 50 kilometers.
