Product Description

Multimode Filter Wavelength Division Multiplexer

(GK-MMFWDM Series)

Description

The Multimode Filter Wavelength Division Multiplexer series is based on environmentally stable thin film filter technology. The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating. These components have been extensively used in multi-mode fiber communication, CATV and testing instrumentation.
The GKER Photonics GK-MMFWDM Series Multimode Filter Wavelength Division Multiplexers are advanced optical devices designed for efficient wavelength management in multimode fiber applications. Utilizing environmentally stable thin-film filter technology, these multiplexers enable precise combining or separating of light at various wavelengths within a broad range. The series is engineered to deliver exceptionally low insertion loss, high isolation, and excellent environmental stability, making it ideal for demanding environments.
These components are particularly well-suited for multi-mode fiber communication systems, CATV networks, and testing instrumentation due to their high-power handling capabilities and robust performance. The unique pigtail processing and high-quality anti-reflective (AR) coating contribute to their superior power handling and reliability. The GK-MMFWDM Series offers a wide selection of wavelengths and fiber core options, accommodating diverse application needs and ensuring optimal performance across different setups.
