In 100G optical modules, single-fiber modules save fiber resources through wavelength division multiplexing (WDM) technology, making them suitable for scenarios with limited fiber resources or long-distance transmission; dual-fiber modules have a simple structure and low cost, making them suitable for short-distance or high-reliability scenarios. The following is a detailed comparative analysis: I...
