The GKER Photonics 980/1550 nm Singlemode Wavelength Division Multiplexers (GK-WDM Series) are precision-engineered components designed to combine or separate light at different wavelengths with exceptional performance. These multiplexers are ideal for applications requiring low insertion loss, minimal polarization dependence, and high isolation. Built with superior environmental stability, the GK-WDM Series is extensively used in Erbium-Doped Fiber Amplifiers (EDFA), Cable Television (CATV) systems, Wavelength Division Multiplexing (WDM) networks, and various fiber optic instrumentation.

These Wavelength Division Multiplexers offer an operating wavelength centered around 980 nm and 1550 nm, ensuring reliable operation with minimal loss. The devices are engineered to deliver maximum insertion loss of just 0.15 dB, making them highly efficient in signal transmission. Additionally, the low polarization dependent loss of 0.1 dB ensures consistent performance regardless of polarization changes.

With a robust design capable of handling continuous optical power up to 300 mW, the GK-WDM Series is perfect for demanding environments. It features a return loss of 60 dB and a directivity of 60 dB, ensuring superior signal integrity. The thermal stability of ≤ 0.002 dB/°C guarantees reliable performance across a wide temperature range from -40°C to +75°C, making it suitable for diverse operating conditions.

Whether you are optimizing your fiber optic network or enhancing your optical communication systems, the GKER Photonics GK-WDM Series is a reliable choice that delivers consistent performance and long-term durability.
