The GKER Photonics Bandpass Filter (GK-BP Series) is an advanced micro optics device engineered to enhance the performance of optical systems by selectively filtering light at a specific wavelength. Designed for high-precision applications, this filter utilizes state-of-the-art thin film technology to provide exceptional performance in blocking unwanted noise signals. Operating at a center wavelength of 1080 nm, the filter is adept at managing optical signals in systems such as Erbium-Doped Fiber Amplifiers (EDFAs) and fiber laser setups.

Key features of the GK-BP Series include a narrow pass bandwidth of 5 nm, ensuring precise signal transmission within the desired range while effectively blocking signals outside this band. The filter boasts a maximum insertion loss of 1.0 dB across the pass band, minimizing signal attenuation and maintaining system efficiency. With an impressive wavelength suppression capability, it significantly reduces noise and interference by attenuating signals in the 1030 - 1070 nm and 1090 - 1150 nm ranges.

The filter's low polarization dependent loss (PDL) of 0.1 dB ensures consistent performance across different light polarization states, while its high return loss of 50 dB for single-mode fiber enhances signal integrity. Capable of handling up to 5 W of continuous wave optical power, this filter is robust enough for high-power applications. It also withstands a maximum tensile load of 5 N, ensuring durability and reliability in various installation environments.

The Bandpass Filter operates effectively within a temperature range of -5°C to +70°C and can be stored in conditions ranging from -40°C to +85°C, making it versatile for diverse operational environments. Its use of HI 1060 fiber contributes to its high performance and stability.
