Some level of divergence will always be present when collimating light. In the illustration below, both systems produce collimated light, however, Figures 2 and 4 have more divergence compared to Figures 1 and 3 due to the sources being larger. Figures 2 and 4 can be thought of as a collection of closely spaced ideal point sources. Individually, each point creates a ray bundle of parallel rays, but as a collection the series of “point sources” create a beam with some divergence. The divergence exists because, as the size of the source increases, the source’s distance from the optical axis increases, and thus the resultant ray bundle’s angle increases with respect to the optical axis.

AFL’s Manja Thessin speaks to Datacentre Solutions Magazine and answers the big questions surrounding the unique cabling and connectivity challenges inside modern, AI-driven hyperscale data centers.

Principle ofoptical fibre

Attenuation, or the loss of light or signal, is nearly unavoidable when installing your fiber network. This blog will explore its two forms: intrinsic and extrinsic attenuation.

This article is part of our Basics of Fiber Series. Other blogs in this series include fiber benefits, the differences between single-mode and multimode and intrinsic and extrinsic attenuation in fiber optic cables.

To minimize divergence of a collimated beam two factors must be balanced: focal length of the collimating system and size of the light source. Equation 1 approximates the divergence of a collimated beam:

In this video segment from the 2024 Data Center Summit, AFL provides best practices for planning, deploying and commissioning the fiber infrastructure underpinning cutting-edge AI networks.

AFL's director of applications engineering and field engineering provides an introduction to fiber optic technology in this presentation recording.

To achieve ideal collimation, the size of the illumination source must be minimized or the focal length of the collimating system must be increased. Note that as you increase the focal length of the system, the system must be physically further away from the source. This means that less light will be captured by the focusing system and overall power in the resultant beam is decreased.

Have you ever thought about the structure of optical fiber? How can a thin strand of glass, about the width of a human hair, transmit vast amounts of data across great distances? Optical fiber is composed of three elements – the core, the cladding and the coating. These elements carry data by way of infrared light, thus propagating signal through the fiber. The core is at the center of the optical fiber and provides a pathway for light to travel. In multimode fiber, the core size is either 62.5 or 50 microns (µm), and approximately 8.3 microns in a single-mode fiber. The larger core size in multimode fiber provides various pathways for light to travel, whereas the small core size in single-mode fiber provides a single pathway. Next is the cladding, which is 125 microns. The cladding holds the light inside the core and controls the direction in which light is spread through the fiber. When light enters the fiber at the appropriate approach angle, also known as the critical angle, it will reflect and stay inside the core, thus achieving a process called “total internal reflection”. If it’s not at the perfect angle, the light will refract and the signal will be lost. Lastly, we have the coating, which acts as the primary buffer. It has a diameter that, historically, has been 250 µm. It cushions and protects the fibers from humidity and hostile environments. Two layers of urethane Acrylate (plastic) make up the coating, also known as the “soft” and “hard” layers. The soft layer cushions the fiber and the hard layer provides abrasion resistance. The coating also has a higher index of refraction than the core and the cladding which allows for unwanted light to refract from the cladding. Additionally, there are new fibers being release to the industry that have a reduced diameter of 200 µm. These allow for smaller cable diameters in ultra-high density fiber optic cables, like 3456 fiber and 6912 fiber cables.  You can learn more about optical fiber in this presentation from Patrick Dobbins, the Director of Applications Engineering and Field Engineering for AFL.

A collimated beam of light is defined when every ray within the beam is parallel to every other ray. To produce collimated light you can either place an infinitesimally small source exactly one focal length away from an optical system with a positive focal length or you can observe the point source from infinitely far away. In the real world, neither of these scenarios are possible. In addition, diffraction theory tells us that even if one of these scenarios were met, there would still be some divergence.
