Takfly's DWDM LGX module utilizes advanced Thin Film Filter (TFF) wavelength division multiplexing technology with multiple wavelength options. This technology multiplexes optical signals of different wavelengths into a single fiber for transmission, and employs demultiplexing at the receiving end to separate the combined signals back into individual wavelengths.
DWDM systems feature channel spacing options of 100GHz, 200GHz, and other configurations, making them ideal for long-distance, high-capacity trunk networks and ultra-large capacity metropolitan area network core nodes.
