Techniques for Placing Optical Cables in the Open Air
When it comes to installing Optical Fiber Cables in outdoor environments, two primary techniques stand out: Trenching for Fiber Optic Cables and Direct Burial Fiber Optic Cables. Each method offers distinct advantages and is tailored to specific environmental considerations. If you're unfamiliar with the fundamental concepts of fiber optic technology, we recommend reading our. Deploying fiber above ground on poles or towers removes the need for underground digging and is particularly useful when the ground is uneven, rocky or both. There are three common laying methods for outdoor optical cables, namely: underground pipeline laying (that is, laying optical cables in underground pipelines), direct underground laying and overhead laying (that is, laying from utility poles to utility poles in the air.
