Availability: InStock

Description

The GKER Photonics Polarization Maintaining Bandpass Filter CWDM (GK-PMBPCWDM Series) is a high-performance optical component designed to ensure superior signal integrity in complex optical communication systems. Leveraging environmentally stable thin-film filter technology, this device effectively blocks unwanted noise signals, making it ideal for use in Erbium-Doped Fiber Amplifiers (EDFAs) and fiber laser systems.

This bandpass filter is engineered to maintain the polarization of the optical signal, ensuring high isolation, low insertion loss, and a high extinction ratio. These features are crucial for applications requiring precise wavelength filtering, such as wavelength-division multiplexing (WDM) systems, where the filter allows specific wavelengths to pass while reflecting or attenuating others. The device is compatible with PM Panda Fiber, making it suitable for high-speed, high-power optical networks.

The GK-PMBPCWDM Series is built to withstand a wide range of environmental conditions, offering excellent stability in both operating and storage temperatures. Its robust construction supports high optical power handling, up to 300 mW continuous wave, and provides reliable performance across multiple wavelength ranges, including 1470 nm to 1610 nm. This makes it a versatile solution for advanced optical systems that demand high precision and durability.
