Fiber Optic Tunable Filter
Description
The Fiber Optic Tunable Filter (FOTF) from GKER Photonics represents a cutting-edge solution in fiber optic technology, utilizing advanced fiber Fabry-Perot interferometer principles. This high-performance filter is designed for precise wavelength tuning across a wide spectral range, driven by a sophisticated piezoelectric actuator. The GK-FOTF Series excels in delivering high accuracy and fast tuning rates, essential for various optical applications.
Featuring a typical Free Spectral Range (FSR) of 150 ±20 nm and a finesse of up to 400, the FOTF provides exceptional wavelength resolution and stability. It achieves minimal insertion loss, with a maximum peak value of 2.5 dB, ensuring efficient signal transmission. The filter also maintains a high Pass Bandwidth of 2.5 nm at -3 dB, facilitating effective signal processing.
The device is engineered for broad operational flexibility, supporting both the C and L bands, with a tuning range extending up to 200 nm as an option. With a resonant frequency of 65 kHz or 75 kHz, the FOTF offers rapid wavelength adjustments, making it ideal for applications requiring swift and accurate filtering. The filter's low polarization-dependent loss (PDL) and high environmental stability ensure reliable performance across varying conditions.
Built with robust temperature stability, it operates within a temperature range of -10°C to +70°C, while its storage temperature range extends from -40°C to +85°C. The GK-FOTF Series is compatible with standard Single Mode Fiber (SMF-28e+), making it a versatile choice for wavelength scanning, spectrum analysis, signal selection, and noise rejection in both research and industrial environments. The device is housed in a compact form factor, measuring 13.5 x 18 x 50 mm, suitable for integration into various optical systems.
