Description
The Singlemode Wavelength Division Multiplexers (WDM) from GKER Photonics Co., Ltd. are advanced optical components designed to combine or separate light signals at different wavelengths with precision. Available in configurations for 1310/1550 nm and 1480/1550 nm wavelength pairs, these multiplexers ensure efficient wavelength management in optical networks. Utilizing high-quality single-mode fibers and thin-film filter technology, they provide exceptionally low insertion loss and minimal polarization-dependent loss.
The GK-WDM Series is built for high performance, featuring excellent isolation and stability across a broad range of temperatures, from -5°C to +70°C. The components are crafted to offer high reliability and durability in various applications including EDFAs (Erbium-Doped Fiber Amplifiers), CATV (Cable Television), WDM networks, and fiber optic instrumentation. Each device is engineered to handle up to 300 mW of continuous optical power, making them suitable for demanding high-power applications.
With a compact and robust design, the GK-WDM Series components are easy to integrate into existing systems. Their precise wavelength management capabilities make them ideal for enhancing the efficiency and performance of modern optical networks.
