The GKER Photonics GK-WDM Series Fused Wavelength Division Multiplexer is engineered to effectively combine or separate light at different wavelengths with high precision and reliability. Designed for single-mode applications, this multiplexer offers superior performance with low insertion loss and minimal polarization dependence. It operates at key wavelengths of 1064 nm and 635 nm, ensuring versatility in various optical setups.

This multiplexer is characterized by its high isolation and excellent environmental stability, making it suitable for demanding applications. With a maximum insertion loss of 0.7 dB at 1064 nm and 1 dB at 635 nm, it ensures efficient signal transmission with minimal loss. The device exhibits a low polarization-dependent loss of 0.1 dB and remarkable thermal stability, with changes in performance limited to ≤ 0.002 dB/°C.

The multiplexer also features a minimum return loss of 55 dB and directivity of 55 dB, enhancing signal integrity and reducing reflections. It supports up to 5 W of continuous optical power and operates reliably within a wide temperature range of -40°C to +75°C. Additionally, it comes in two fiber jacket options and can be customized based on specific requirements, including fiber type and length.
