The Demand and Challenges of Ultra-High-Capacity Optical Fiber Communication

The Surge of Data Flood

Data traffic is growing explosively. Forecasts predict hundreds of zettabytes by 2025. 5G adoption and AI computing demands drive this surge. Optical communication must evolve to meet the challenge. Single-fiber capacity is the critical frontier. Future networks demand terabit-level transmission. This is the inevitable trajectory of the industry.

Limits of Traditional Technology

Wavelength Division Multiplexing (WDM) once boosted capacity. It transmits data via multiple wavelengths. Yet, spectral efficiency nears the Shannon limit. Coherent detection enhances signal quality. Still, capacity ceilings persist. Traditional single-mode fibers falter. A new technological path is essential.

 

 

The Necessity of SDM and MCF

SDM leverages the spatial dimension. It vastly expands transmission channels. MCF increases core count within a single fiber. Together, they promise a capacity leap. These are the next-generation solutions. HTF has strategically invested in this domain. Its innovations secure a leading edge.
