Why does the OPGW Live Line replace the buried data cable?
A primary reason the initial expansion of data cables spanned several decades was cost and a variety of external factors that telcos had difficulty controlling. These problems arose because all the data cables were forced to bury. The last decade has seen an increase in OPGW (fiber optic composite ground wire). This new design allowed for a compact and interference-free signal while taking advantage of power lines instead of being buried. Power grids have connected population centers for decades and now also provide an alternative telecommunications route.
No conflicts for the right of way
One of the toughest problems telcos faced when trying to bury their data cable was right-of-way conflicts. The first problem was that civil works had to approve the cable route before excavation began. This was to ensure that the burial process would not cause damage to existing buried power lines or public works infrastructure, such as the water and sewer system. The second problem was competing with other telecommunications companies and associated companies for specific rights related to the land. As a result, many smaller communities only had one or two telecommunications companies to choose from. An OPGW live line enables telcos to quickly add and connect data cables over the existing transmission line infrastructure avoiding all right-of-way conflicts.
No threat of accidental injury or damage
Maintaining and replacing buried data cable can quickly become an expensive proposition. There are many potential problems that can seriously injure people or the data cable when buried underground. The most common problem is in residential areas when a homeowner digs in their yard and accidentally damages the data cable. To minimize the possibility of this happening, telcos would use additional cables and materials for additional protection, resulting in higher installation costs. By using an OPGW live line, a telco is relying on long-established safeguards built into the outdoor infrastructure.
More profitable than burying cables
A great benefit to OPGW live line installation is cost effectiveness. There are a variety of different ways that using an OPGW live line proves to be more cost effective than burying the wire. The first area of cost savings is the elimination of the excavation and backfilling process, as well as the outer casing tubing required to bury the cable. The second area of payoff is how OPGW live lines are installed. Instead of buying or renting heavy machinery, telecommunications companies use a variety of smaller tools, such as a support roller, mobile unit, retrieval machine, tension cable grab, and a variety of rope to lay the rope. live line OPGW. This process is also noticeably faster, reducing the number of man hours required to complete the project.
No service interruption required
The last reason OPGW’s live lines are popular is the ability to maintain service. If the lines are already connected to an existing telecommunications data infrastructure, it is not necessary to stop the service to connect the lines. The entire installation process can take place without interrupting service to your customers.
