Description
The GKER Photonics 2 µm Filter Wavelength Division Multiplexer (GK-FWDM Series) is a high-performance optical device designed to facilitate efficient wavelength division multiplexing (WDM) in advanced fiber-optic systems. Leveraging cutting-edge thin-film filter technology, this multiplexer excels in combining or separating light across a wide range of wavelengths with unparalleled precision.
Engineered to meet the rigorous demands of modern optical applications, the GK-FWDM Series ensures exceptional performance with its low insertion loss, high isolation, and minimal polarization dependence. The device is optimized to deliver a typical insertion loss of 0.6 dB and a maximum insertion loss of 0.8 dB, while providing a typical isolation of 30 dB and a minimum isolation of 25 dB. The reflect band operates efficiently with a wavelength range of 1560 - 1580 nm, ensuring excellent performance in various optical systems.
Designed with high power handling capability in mind, the GK-FWDM Series can manage up to 300 mW of continuous wave optical power. This is achieved through advanced pigtail processing and high-quality anti-reflective (AR) coatings, which contribute to its superior durability and reliability. The multiplexer’s low polarization dependent loss, with a maximum of 0.2 dB and a typical value of 0.1 dB, further enhances its suitability for high-speed WDM network systems where signal integrity is critical.
The device is housed in a robust package that ensures excellent environmental stability, operating reliably across temperatures from -5°C to +70°C and withstanding storage temperatures ranging from -40°C to +85°C. This makes it ideal for deployment in diverse and challenging environments.
The GK-FWDM Series is versatile in its fiber compatibility, offering options for PM 1550 Fiber and PM 1950 Fiber configurations to meet specific application requirements. With its precision-engineered design and high-performance specifications, the GK-FWDM Series is an excellent choice for enhancing the functionality and efficiency of WDM networks, erbium-doped fiber amplifiers (EDFAs), Raman amplifiers, and other fiber-optic instruments.
