What is a potential issue caused by not properly securing buffer tubes in a splice closure?

Not properly securing buffer tubes in a splice closure can lead to a loss of signal integrity. Buffer tubes are designed to protect and organize the optical fibers within them. If they are not secured correctly, it can cause fibers to bend or break, leading to increased attenuation or signal loss. This can result in data transmission errors, reduced performance of the network, and overall degradation of the optical signal quality. Ensuring that buffer tubes are properly secured is crucial for maintaining the integrity of the fiber optic connection, which is essential for high-speed data transfer.

While the other options mention difficulties with installation, potential cost increases, and internet instability, these consequences are secondary effects that may result from the primary issue of compromised signal integrity. Prioritizing the proper management and securing of buffer tubes directly addresses the core concern of maintaining effective communication through optical fibers.
