The primary consideration in selecting a route for fiber optic cable through cable trays and ducts is to ______.

Selecting a route for fiber optic cable through cable trays and ducts is crucial for ensuring the integrity and longevity of the installation. The primary consideration should be to avoid potential cutting edges and sharp bends. This is important because fiber optic cables are particularly sensitive to physical stresses. Sharp bends can lead to microbending and macrobending, which can impair signal transmission and even cause permanent damage to the fibers inside the cable.

Furthermore, cutting edges can pose a significant threat to the cable’s outer sheath, which protects the delicate fibers from environmental factors and physical wear. Ensuring a smooth, gradual path for the cable not only helps maintain its performance but also reduces the risk of future maintenance issues. By focusing on avoiding potential damage from sharp angles and rough surfaces, the installation can achieve greater reliability and efficiency in data transmission.
