How long is the production expansion cycle for fiber optic cables

How long is the production expansion cycle for fiber optic cables

Long Expansion Cycle: Optical fiber preform production has high technological barriers, and the expansion cycle can take as long as 18-24 months. Even if manufacturers start expanding immediately, the new capacity will not be available until at least 2027. This phenomenon is the result of multiple factors, including tight supply of optical fiber preforms (preforms), long expansion cycles for optical fiber production capacity, and the explosive growth of emerging applications such as AI computing power and drones. The expansion cycle of optical fibers is generally less than 6 months, and fiber optic cables can take 3 months.
