Filter Wavelength Division Multiplexer (GK-FWDM Series)

Filter Wavelength Division Multiplexer (FWDM) is a device based on environmentally stable thin film filtering technology that can combine or separate light of different wavelengths over a wide range of wavelengths. This device provides very low insertion loss, low polarization dependence, high isolation, and excellent environmental stability. Through unique tail fiber processing and high-quality AR (Anti Reflection) coating, they are capable of handling high power and have been widely used in EDFA (Erbium Doped Fiber Amplifier), Raman amplifiers, WDM (Wavelength Division Multiplexing) networks, and fiber optic instruments.

Here are some key features of Filter WDM:

Low insertion loss: This device provides very low insertion loss, ensuring efficient transmission of signals through the device.

Low polarization dependence: Due to their low polarization dependence, these devices process optical signals of different polarization states uniformly, which is crucial for maintaining signal integrity and quality.

High isolation: High isolation means that these devices can effectively isolate signals of different wavelengths, reducing interference between signals.

Excellent environmental stability: These devices can maintain stable performance under different environmental conditions, which is particularly important for fiber lasers and testing instruments that need to operate in variable environments.

High power processing capability: Through unique tail fiber processing and high-quality AR coating, these devices are able to process high-power optical signals, making them suitable for high-power fiber lasers and amplifiers.

Wide wavelength coverage: These devices are capable of working effectively at standard wavelengths of 1310 nm and 1550 nm, and can cover a wider range of wavelengths with excellent uniformity.

Customized services: Based on different application requirements, we can provide customized wavelength combinations, bandwidths, fiber lengths, and connector types.

These characteristics make Filter WDM an ideal choice for fiber lasers, fiber amplifiers, coherent communication systems, fiber optic gyroscopes, and other high-performance network applications. By precisely controlling the wavelength state and power allocation of light, Filter WDM helps improve the overall performance and reliability of the system.
