635-1064 nm Wavelength Division Multiplexers
Description
The GKER Photonics 635/1064 nm Wavelength Division Multiplexer (WDM) from the GK-WDM Series is a high-performance singlemode optical component designed to combine or separate light at 635 nm and 1064 nm. This WDM unit is engineered for use in a variety of advanced fiber optic systems, offering exceptionally low insertion loss, minimal polarization dependent loss (PDL), and high channel isolation. With a thermal stability of ≤0.002 dB/°C, it ensures consistent performance even in fluctuating environmental conditions.
Built using high-quality components and precision manufacturing, the multiplexer supports up to 5 W of continuous wave optical power and offers excellent return loss and directivity. It is available in multiple configurations, including 1×2 and 2×2, and supports fiber types such as Corning HI1060 and Nufern FUD-3584, with options for 250 µm bare fiber or 900 µm loose tube jackets.
Ideal for use in EDFA systems, CATV infrastructure, WDM networks, and fiber optic instrumentation, the GK-WDM Series is a reliable solution for applications demanding both wavelength specificity and environmental resilience.

Frequently Asked Questions
The primary function of this WDM multiplexer is to combine or separate optical signals at two specific wavelengths—635 nm (visible) and 1064 nm (infrared)—within a single optical fiber. This allows for more efficient use of fiber bandwidth and simplifies fiber optic system architectures by minimizing the number of required fibers.
The GK-WDM Series is designed to handle continuous wave optical power up to 5 watts, making it suitable for applications like medical laser systems, high-power sensing, and industrial laser delivery. Its robust construction and low insertion loss help maintain stable performance at elevated power levels.
This multiplexer features excellent thermal stability with a temperature coefficient of ≤0.002 dB/°C. It operates reliably over a wide temperature range from –40°C to +75°C and can be stored between –40°C to +85°C, making it ideal for harsh or outdoor environments.
The GK-WDM Series supports fiber types such as Corning HI1060 and Nufern FUD-3584. It is available with either 250 µm bare fiber or 900 µm loose tube jacket options and can be ordered with or without standard fiber connectors depending on your system requirements.
This device is widely used in optical communication systems, including EDFA amplification chains, CATV signal distribution, and WDM-based networks. It is also applicable in fiber optic instrumentation and medical laser delivery systems, where combining or separating light of different wavelengths is critical.
