What is a cable tray or cable trough
Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough. A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Small cables may exit the tray throug.

What is the cable tray structure for optical fiber
Fiber optic splice trays are used in a variety of telecom and FTTH applications: Installed inside dome or horizontal SLT closures, used to manage fiber splice in core, distribution, and access networks. Their primary function is mechanical rather than optical. According to the 2014 National Electric Code® (NEC), any listed optical fiber cable is acceptable for a tray application. Since the need for higher data rates and effective communication gets more robust, the utilization of optical fibers has become increasingly widespread across multiple spheres of. Optical fiber termination by fusion splicing or mechanical splicing is very common now with the increasing development of fiber optic network. As optical fibers are sensitive to pulling, bending and crushing forces, fiber splice tray is used to provide a safe routing and easy-to-manage environment. NEC Article 392 explains cable trays, their components, appropriate wiring methods for cable trays, and instances where they are and are not permitted for use.
