Risks of Shallow Burial of Optical Cables
Shallow burial increases the chance of physical damage, signal loss, and costly repairs from construction, weather events, or animal interference. Burial depths are guided by international and regional standards, tailored to environmental and safety needs: The International Telecommunication Union (ITU) and Institute of Electrical and Electronics Engineers (IEEE) recommend a minimum depth of 0. 8 million km in scope by 2025 (per TeleGeography), burying these cords of light comes with the benefits of avoiding cable damage, decreasing downtime, and extending their operational lifetime. But how deep is fiber optic cable buried?The purpose of this document is to present a new 'open source' Cable Burial Risk Assessment Method which advances the BPI method. Using probabilistic analysis the new method can be used to optimise the specified depth of lowering. However, whether with respect to FTTH (Fiber to the Home), long-distance transmission, or data center interconnects, among many others, there arise questions like: How deep do fiber optic cables go? What steps.
