In the electrical engineering, we are often interested in communicating or transferring electrical signals/energy from one point to another. To do this interconnection between electrical devices is required. Fiber cable transmits data by converting the electrical pulses into light pulses that are why fiber cables provide high signal transmission rate relative to copper wires. Surely, the speed of light is greater than the speed of electric charge.
When cables run overhead they can Sag with time. To support the cable to keep it from sagging a messenger wire can be lashed with it but then there are figure 8 fiber cables.
Construction of Figure 8 Fiber Cable
This figure 8 fiber cables have a messenger wire built into the cable. In this figure 8 fiber cable, the only thing that is needed to tightly tie both the clamps of the messenger cables and it will absorb all the tension on the cable. The core of figure 8 fiber cables contains strands of fiber cables filled with core and tube filling compounds. The core is then wrapped and aluminum coating and enclosed inside the bedding layers. These bedding layers are the enclosed inside the outer jacket eliminating all the damages the UV/Heat could.
Uses of Figure 8 Fiber Cable
Figure 8 Fiber Cables are most common with telephone cables. The reason is that they are often run overhead into residential and commercial areas. The messenger in the figure 8 Fiber cable is made up of extra-strength galvanized steel. The zinc coating prevents the steel from rusting and increases the lifespan of the fiber cable.
Types of Figure 8 Fiber Cable
Fiber 8 Fiber cables do provide a solution for sagging of electric wires and the ability to withstand harsh environmental conditions. This figure 8 fiber cable could be in a variety of different types which are named as follows.
- Central tube
- Stranded loose tube
