1528 -1565nm Bandpass Filter

Name: 1528 -1565nm Bandpass Filter
Brand: GKER Photonics
Availability: InStock

Description

The GKER Photonics Bandpass Filter (GK-BP Series) is a high-performance micro-optics device designed to selectively transmit a specific range of wavelengths while blocking unwanted signals. Utilizing advanced thin-film filter technology, this bandpass filter offers superior environmental stability and is particularly effective in applications like Erbium-Doped Fiber Amplifiers (EDFAs) and fiber laser systems, where precision and reliability are paramount.

With a wavelength range of 1528 to 1565 nm, the GK-BP Series is engineered to deliver exceptional performance with a typical insertion loss of just 0.5 dB and maximum insertion loss of 0.7 dB. The filter ensures minimal signal distortion with its low polarization-dependent loss (PDL) of 0.05 dB, making it ideal for high-fidelity optical communication systems. Its high isolation (minimum 12 dB for wavelengths below 1521 nm and above 1574 nm) effectively eliminates noise, enhancing signal clarity.

Designed for robustness, the Bandpass Filter can operate in harsh environments with an operating temperature range of -40°C to +105°C and storage temperature range of -40°C to +85°C. The device also boasts a high power handling capability of up to 300 mW and is compatible with standard SMF-28 fiber.

Whether used in DWDM systems, optical sensors, or compact optical circuits, the GK-BP Series Bandpass Filter provides unparalleled reliability and performance, making it a crucial component in cutting-edge fiber optic communication systems.
