product description
The Filter Wavelength Division Multiplexer (FWDM) from GKER Photonics, as detailed in the provided search results, is a high-performance optical device designed for precision wavelength management in optical communication systems. It is based on environmentally stable thin-film filter technology, which allows it to combine or separate light at different wavelengths within a wide wavelength range. Here are some of its key features and specifications:
Low Insertion Loss: The FWDM offers very low insertion loss, with a maximum of 0.7 dB for the pass band wavelength range of 980 ± 10 nm, ensuring efficient light transmission with minimal power loss .
High Isolation: It provides a minimum isolation of 25 dB, which effectively suppresses back reflections and unwanted signals, enhancing the signal-to-noise ratio and system performance .
Low Polarization Dependence: With a maximum polarization-dependent loss (PDL) of 0.1 dB, the FWDM ensures consistent performance regardless of the input light's polarization state .
High Return Loss: The device has a minimum return loss of 50 dB, which helps to prevent signal interference and distortion .
Excellent Environmental Stability: The FWDM is designed to operate reliably within a wide temperature range of -5°C to +70°C, and can be stored in conditions ranging from -40°C to +85°C, making it suitable for diverse operational environments .
High Power Handling Capability: Through unique pigtail processing and high-quality AR coating, the FWDM can handle high laser power, making it suitable for use in high-power applications such as EDFAs, Raman amplifiers, WDM networks, and fiber optical instruments .
Telecordia Compliance: The device is compliant with Telcordia GR-1209-CORE-2001 and ITU-T G.694.1 standards, ensuring reliability and performance in mission-critical applications .
These features make the Filter Wavelength Division Multiplexer an indispensable component in advanced optical systems where precision, reliability, and efficiency are paramount. Its ability to handle high power levels, combined with its low loss and high isolation characteristics, contribute to its reputation as a pinnacle of engineering excellence in the field of optical communication systems.
