The engineering needed for optical fiber installation
Installing optical fiber is the core business of FiberOne. As the company name itself suggests, FiberOne focuses on building telecommunications networks by optical fiber installation. Below is a short presentation of important aspects we take into consideration with every new installation of optical cables.
There are four principles which installers base their work upon. We mention them shortly, deeming it useful for future partners to know the way we do the job:
1. Environmental limits - new projects usually have technical specifications including environmental limits. However, there is the risk to oversee some limitations not rigorously mentioned in the datasheet. Therefore, our specialists are obliged to take into account five possible environmental conditions: moisture, operating temperature range, bend radii, crush loads, use load.
2. Installation limits - the cable can be either pulled into its path or placed in its location, depending on the cable type. In the former case, the installation limits are: no twisting, installation load, installation bend radius, installation temperature range, storage temperature range.
3. Reducing the load - two methods are available for reducing the load applied to the cable: lubricant and a "Figure-8" installation.
4. Cable placement - in cable placement, it is recommended to segregate fiber cables. Whenever copper and fiber cables reside in the same tray, the installer places the fiber cables in innerduct. A common practice is to use service loops. Service loops are lengths of excess cable that can be pulled into problem areas.
Some particularities regarding optical cables installation are described as follows:
Each datasheet is customized for the project it was designed for. There are, however, several common factors that can be found in every datasheet, among other specifications:
A. A complete design has to be done before beginning cable plant installation.
B. It is recommended to work with vendors on component specifications to get best quality.
C. All components must be available before beginning installation, for a prompt and proper set up.
E. Safety issues must be reviewed, and rules for the installation must be defined accordingly.
F. The cable plant is to be installed.
G. The cable plant is submitted to testing and troubleshooting.
H. The communications systems have to be installed.
I. The fiber optics network is finally documented.
