Installation Fiber Optic Cable Aerial
Fiber optic cable aerial installation can be done in two ways, Lashing a fiber optic cable to a steel messenger and Self-supporting (Figure-8) optical fiber cables. To make it clear there are below their description.
Lashing a fiber optic cable to a steel messenger
A steel messenger is first installed between the poles. Then a cable reel trailer and truck are used to pull the cable along the messenger. Cable guide and cable lashers are used to wrap around both the messenger and the fiber cable to secure the fiber cable to the messenger. Following the cable lasher is an aerial bucket truck which makes necessary adjustments.
At each pole, the fiber optic cable forms an expansion loop to allow for expansion of the messenger. The expansion loop’s sizes have both a length and a depth; its length should be larger than twice its depth. The fiber cable should also maintain its minimum bending radius at all times.

Self supporting optical fiber cables
Self-supporting (Figure-8) optical fiber cables greatly simplifies the task of placing fiber optic cables onto a aerial plant. The self-supporting figure-8 cable incorporates both a steel messenger and the fiber cable into a single jacket of Figure-8 cross section.
The combination of strand and optical fiber into a single cable allows rapid one-step installation and results in a more durable aerial plant.
