The T&S TFF 200GHz DWDM Module is a high-performance optical device designed for Dense Wavelength Division Multiplexing (DWDM) systems. This module operates with a 200GHz channel spacing, enabling efficient wavelength management and high-capacity data transmission over optical fiber networks. With low insertion loss, high isolation, and exceptional performance across a wide wavelength range, it ensures optimized signal integrity and reliable connectivity for long-haul and high-speed communication systems.
