How to install underground fibre optical cables ?

—Doing a Pre-survey

The purpose of this survey is to plan the cable route which will determine the aerial cable installation method to be used, as well as the equipment and material requirements. Or if any work should be required along the proposed route before cable deployment begins.

—Installation Issues

Investigating the characteristics of the ground along the route to eliminate unnecessary problems. Before aerial cable deployment, clearance problems over roadways, driveways, etc. should be taken into consideration. Trees or other obstructions, which could hinder the placing operation, should be noted.

—Splice Locations

In the survey, choosing the splice locations, and make plans for splice closures and cable slack storage. The selection of splice locations in the survey allows verification of the transmission design and make preparation for cable order lengths. Besides, these locations should not lie in sites where access is inconvenient or hazardous.

—Materials Required

There are lots of unexpected factors occurring during the aerial fiber optic cable installation. Cable quantity and other materials must be ordered. Special requirements for sequencing the cable shipments must be specified in the cable order.

Installation Tools

Outdoor fiber optic cable plant is harder than indoor optical cable installation. When deploying aerial fiber optic cable outside, some tools are essential. Here are some common tools for aerial fiber cable installation.

AirFiber received $96.1 million in funding, and never solved the weather issue. They sold out to MRV communications in 2003, and MRV sold their FSO units until 2012 when the end-of-life was abruptly announced for the Terescope series.[7]

LightPointe Communications received $76 million in start-up funds, and eventually reorganized to sell hybrid FSO-RF units to overcome the weather-based challenges.[20]

The Maxima Corporation published its operating theory in Science (magazine),[21] and received $9 million in funding before permanently shutting down. No known spin-off or purchase followed this effort.

Wireless Excellence developed and launched CableFree UNITY solutions that combine FSO with millimeter wave and radio technologies to extend distance, capacity and availability, with a goal of making FSO a more useful and practical technology.[22]

One private company published a paper on November 20, 2014, claiming they had achieved commercial reliability (99.999% availability) in extreme fog. There is no indication this product is currently commercially available.[23]

Extraterrestrial

The massive advantages of laser communication in space have multiple space agencies racing to develop a stable space communication platform, with many significant demonstrations and achievements.

Operational systems

The first gigabit laser-based communication was achieved by the European Space Agency and called the European Data Relay System (EDRS) on November 28, 2014. The system is operational and is being used on a daily basis.
