2 µm Fused Wavelength Division Multiplexer
Description
The 2 µm Fused Wavelength Division Multiplexer (GK-WDM Series) from GKER Photonics Co., Ltd. is engineered to combine or separate light at 1570 nm (or 800 nm) and 2000 nm windows, making it an ideal choice for advanced optical systems. This multiplexer is specifically designed to provide superior performance with very low insertion loss, ensuring minimal signal attenuation and maintaining signal integrity across the operating wavelengths. The device also offers excellent environmental stability, making it highly reliable in various demanding conditions.
This multiplexer operates over a wide wavelength range, accommodating longer operating wavelengths of 2000 ± 20 nm and shorter wavelengths such as 1570 ± 20 nm, 800 ± 20 nm, or 650 ± 20 nm. The device is characterized by its minimal polarization-dependent loss, ensuring consistent performance regardless of the polarization state of the input signal. Additionally, the multiplexer exhibits a high return loss and directivity, contributing to enhanced signal quality and reduced interference.
With its robust design, this multiplexer is suitable for a variety of applications, including optical fiber communication, sensing, and laser systems, where precise wavelength management and signal fidelity are critical. The multiplexer’s ability to handle up to 500 mW of continuous optical power further expands its versatility, making it a reliable choice for both research and commercial use.
