Adjustable Dispersion Compensation (TDC)

The Adjustable Dispersion Compensation (TDC) module provides a flexible solution for managing chromatic dispersion in high-speed optical communication systems. Unlike fixed compensation solutions, the TDC can dynamically adjust its dispersion compensation parameters, making it highly suitable for networks where conditions can change or where different transmission distances are involved. This feature is particularly beneficial in 10G/40G/100G long-distance optical communication systems and data center interconnections, where maintaining signal integrity is crucial. By employing temperature regulation for precise dispersion adjustment, the TDC ensures optimal performance under varying network conditions.
