1×2/2×2 Fused WDM, 1480/1550nm

The 1×2/2×2 1480/1550nm Fused WDM is a wavelength division multiplexing device that uses fused technology to combine or separate optical signals at 1480nm and 1550nm wavelengths. The 1480nm wavelength is commonly used as the pump light in erbium-doped fiber amplifiers (EDFA), while the 1550nm wavelength is the standard for long-distance fiber optic communication due to its low loss. Available in 1×2 and 2×2 configurations, the 1×2 version can combine or split signals at different wavelengths, and the 2×2 version can manage the combination or splitting of two wavelengths across two ports. This device is widely used in EDFA systems and WDM networks, enhancing bandwidth and transmission efficiency by enabling multiple wavelengths to be transmitted simultaneously on a single fiber.
