1×2/2×2 Fused WDM, 980/1550nm

The 1×2/2×2 980/1550nm Fused WDM is a wavelength division multiplexing device made using fused technology, designed to combine or separate optical signals at 980nm and 1550nm wavelengths. The 980nm wavelength is typically used as the pump light in fiber amplifiers, while the 1550nm wavelength is the standard transmission wavelength in fiber optic communications. This device is available in 1×2 and 2×2 configurations. The 1×2 version can split a single wavelength into two output ports or combine two wavelengths into one output port, while the 2×2 version allows for the combining or separating of two wavelengths between two ports. It is widely used in fiber amplifiers (such as erbium-doped fiber amplifiers, EDFA) and WDM communication systems, helping to enhance transmission capacity and signal quality.
