Why are there no optical fiber cables for communication
The transmission distance of a fiber-optic communication system has traditionally been limited by fiber attenuation and by fiber distortion.

PVC pipe laying for communication optical cables
PVC Riser Pipe is a lightweight, flame-retardant plastic conduit specifically designed to encompass and shield fiber optic cables. It shields cables from environmental hazards such as wind, rain, UV rays, and physical damage caused by accidental snags or deliberate vandalism. These conduits offer a range of benefits suited to the specific needs of these environments. They can be used in all areas of general construction and civil engineering, in road construction and also in the construction of tunnels and tracks. Whether for underground or overground installations, you have a wide choice of cable protection solutions to ensure your power and cable lines are fully protected during repair, retrofitting or constrution work. Either rigid or flexible, made of PE, PP or PVC, sand-proof, waterproof or fireproof. PVC-U is the most commonly used material for electrical conduits due to its lightweight, ease of assembly.

What current is generally suitable for optical fiber communication cables
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. 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. This list includes both standards-based and real-world technical cable types utilized in fiber-optic infrastructure, telecoms, enterprise, and outdoor applications.

The role of primary communication optical cables
The primary function of fiber-optic cables is to transmit large amounts of digital data as pulses of light over long distances — quickly, securely, and with minimal signal loss. Some of the first commercial fiber links were deployed in the mid-1970's and operated at 45 Mbit/sec. Since then, research and development has allowed a single strand of fiber to carry.
