Product Profile
A 1550nm Gaussian Filter(GFF) is a type of optical filter that is commonly used in fiber optic communications systems. This type of filter is designed to selectively attenuate or block specific wavelengths of light while transmitting other wavelengths. It is commonly used in a variety of fiber optic applications, including optical amplifiers, optical add-drop multiplexers, and other types of optical filtering and signal processing systems. It is also used in fiber optic communications networks to improve the quality and reliability of data transmission.
The unique design of OPTICO Customized GFF Device allows it to transmit a range of wavelengths within a narrow band centered at 1550nm,resulting in improved system performance and reliability. Its applications include optical amplifiers, WDM, and other types of optical filtering and signal processing systems.
Products Featrures
Miniaturized package: With an integrated design and small dimensions size that reduce cost and space, it provides an excellent product solution applied to the field of EDFA.
High stability and reliability: The customized GFF minimises interference from the laser while flattening the gain on the wavelength band. And it meets the 168 hours PCT experiments.
Improved Signal-to-Noise Ratio (SNR): OPTICO GFF helps to improve the SNR of the signal by selectively filtering out unwanted wavelengths of light. This reduces optical noise and distortion, leading to more accurate and reliable data transmission.
