The GK-PMFWDM Series from GKER Photonics represents the pinnacle of advanced optical multiplexing technology, specifically designed to cater to high-performance, high-speed wavelength division multiplexing (WDM) systems. This series leverages state-of-the-art thin-film filter technology to offer a reliable solution for combining or separating light at distinct wavelengths while meticulously maintaining the polarization state of the optical signals.

Crafted with a focus on durability and precision, these multiplexers exhibit exceptional performance characteristics including extremely low insertion loss, which is typically around 0.6 dB and can reach a maximum of 0.8 dB. This low insertion loss ensures minimal signal degradation and optimal efficiency in transmission. The devices are engineered to deliver high isolation, with typical values around 30 dB and a minimum of 25 dB, effectively minimizing signal crosstalk and ensuring clear, uninterrupted data channels.

In addition to their excellent isolation and insertion loss metrics, the GK-PMFWDM Series provides superior return loss, with a minimum value of 50 dB, which is crucial for preventing signal reflections that can adversely affect performance. The polarization-dependent loss is remarkably low at a typical value of 0.005 dB, preserving the quality and integrity of the transmitted signal across varying polarization states.

These multiplexers are built to handle high optical power levels, with a continuous wave power rating of up to 300 mW. They also offer excellent thermal stability, functioning reliably across a wide temperature range from -5°C to +70°C. The high tensile load capacity of 5 N further enhances their durability in various installation environments. The series supports a range of fiber types and provides flexibility in connector and fiber jacket options, making it an adaptable choice for diverse optical applications, including telecommunications networks, high-speed WDM systems, and sophisticated fiber optical instruments.

With their advanced design and robust performance characteristics, the GK-PMFWDM Series ensures that your optical systems operate at peak efficiency and reliability, even in the most demanding conditions.
