The GKER Photonics 976/1064 nm Singlemode Wavelength Division Multiplexers (GK-WDM Series) are precision optical devices designed to manage light signals at 976 nm and 1064 nm wavelengths with high efficiency. Utilizing advanced thin-film filter technology, these multiplexers offer exceptional performance in combining or separating light signals with minimal insertion loss, which is critical for maintaining signal integrity in high-performance applications.

These multiplexers are engineered to deliver a maximum insertion loss of just 0.35 dB, ensuring that signal transmission remains highly efficient. They feature a low polarization dependent loss of 0.15 dB, which minimizes the impact of signal polarization variations on performance. High isolation, with a minimum of 13 dB, allows for effective separation of signals, reducing interference and crosstalk in complex optical systems.

Designed for durability and reliability, the GK-WDM Series components excel in environmental stability, with a thermal stability rating of ≤ 0.002 dB/°C, making them suitable for use across a wide temperature range from -40°C to +75°C. They also offer high return loss and directivity, with minimum values of 55 dB, ensuring accurate signal routing and minimal reflections.

The multiplexers are capable of handling optical power levels up to 300 mW, providing robustness in high-power applications. Their versatility makes them ideal for a variety of uses, including in Erbium-Doped Fiber Amplifiers (EDFA), Cable Television (CATV) networks, Wavelength Division Multiplexing (WDM) systems, and other fiber optic instrumentation where reliable signal management is essential.
