In what scenario is the intermediate pull technique necessary for fiber-optic cable installation?

The intermediate pull technique is essential in scenarios where the cable route has multiple 90° bends. This technique allows for better control and reduced stress on the fiber-optic cable during installation. When navigating sharp turns, such as those created by 90° bends, the risk of damaging the delicate fibers increases. Therefore, the intermediate pull technique helps to manage the tension and minimize the likelihood of kinking or breaking the fiber.

This method typically involves using additional pulling points or friction reducers to facilitate a smoother transition around bends. By doing so, the installation team can ensure a safer and more effective deployment of the cable, mitigating potential installation challenges that would arise from sharply navigating bends, which can lead to complications in maintaining signal integrity and performance.
