Figure 8 Fiber Optic Cable

Figure 8 Cable & Specifications

As a self-supporting aerial fiber cable, figure 8 fiber optic cable is a kind of fiber optic cable that is suitable for long-distance communication and inter-office communication. With steel stranded wire as the self-supporting part of the fiber optic cable, it can meet the very high tensile strength during installation and operation.


Figure 8 shape and steel wire messenger also save the installation costs. This cable is a small size figure 8 fiber optic cable. With advantages of light, flexible and easy to construction, it’s also one of the alternative cable for FTTH cabling network.

The figure-8 telecommunications cables are self-supporting cables. They represent a cost-effective and easy to install overhead solution, while also offering stable performances in a large range of operating temperatures. These cables are built with a messenger (steel or dielectric) and an optical fiber or copper cable core, both of them protected by a sheath forming a Figure 8 cross-section. The upper part of the figure 8 cable that serves as messenger wire is designed to withstand mechanical and environmental loads to which the cable will be exposed once installed (frost, snow, wind, …).


We define the allowable tensile force depending on the span and the temperature range in which the cable can be used. This tensile force can register lower values for the span rolled out between the last pole and the anchoring point placed outside the building to be connected. Thus, telecom installers must pay a special attention to this one in order to guarantee the respect of the minimum bend radius during the deployment of fiber optic networks.

INTRODUCTION

To ensure future-proof networks, the clamping of figure-8 cables must be carried out in accordance with the engineering rules established by the owners of the energy or the telecommunications networks on which the telecom lines will be rolled out. Thus, depending on the network configuration, the choice of an anchor clamp or a suspension device must also take into consideration:

The technology used by the cable to be deployed (fiber optics or copper)
The messenger type: steel or dielectric
The maximum allowable range for the cable deployment

How to install figure-8 overhead insulated cables ?

An overhead line always starts with an anchor on the first pole used for this matter.  The cable is then uplifted and maintained onto the next pole with the use of a suspension device.  The operation continues up to the fifth pole, at most, where a second anchor will be installed.  However, cables can be anchored as many times as considered to be necessary, especially when the figure-8 cable installation involves a road crossing, rugged terrain network configuration or any other relevant situation. 

In case of dead-ending applications performed on figure-8 overhead lines, when clamping, the jaws of the figure-8 clamp puncture the messenger insulator and anchor on the steel part.  However, for the roll-out of fiber optic figure-8 cables, the messenger's sheath must remain unaltered.  Dead-ending or suspension of figure-8 cables must therefore be carried out without damaging the insulation of these cables.
