Single-mode fiber does not have chromatic aberration right
Single-mode fibers, used in high-speed optical networks, are subject to Chromatic Dispersion (CD) that causes pulse broadening depending on wavelength, and to Polarization Mode Dispersion (PMD) that causes pulse broadening depending on polarization. In fiber-optic communication, a single-mode optical fiber, also known as fundamental- or mono-mode, is an optical fiber designed to carry only a single mode of light - the transverse mode. Note that in most cases light with different polarization states can be guided.

What size should the bottom opening on the side of the cable tray be
The standard bottom configuration for ventilated trough cable tray is a corrugated bottom with 27/8 inch bearing surfaces - 6 inches on centers and 21/4 inch x 4 inch ventilation openings. They are commonly used where cable support uniformity and cable containment are more important than maximum airflow. Standard Widths: Sidewall Heights: Standard Lengths: Material Thickness by. The primary rulebook used in the safe use of cable trays is NEC Article 392. Note that wider rung spacings and wider cable tray widths decrease the overall strength of the cable tray. Cables Smaller than 4/0 AWG/Kcmil (120 Sq. 10 (B) (1), the smallest size single conductor allowed to be installed in a cable tray is 1/0 AWG.
