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.

Simplex fibre optic cables, also known as single-strand, have only one fibre. It is ideal for situations where data needs to be sent in one direction and does not need data sent back for any purpose. The core of the fiber is made of a highly transparent material, which allows the light to travel through it with minimal attenuation or loss of signal. In recent years, the mainstream single strand fiber transmission technology is based on two wavelengths traveling in opposite directions (also. Typically, single mode fiber optic cables are made from a single glass fiber strand, resulting in a very narrow core diameter of around 9µm.
