Product Description

980/1060 nm Singlemode Coupler

(GK-SMC Series)

Description

The GKER Photonics 980/1060 nm Singlemode Coupler, part of the GK-SMC Series, is engineered for precision and
reliability in high-performance optical systems. This coupler excels in power splitting and monitoring, offering a wide
wavelength range with minimal insertion loss and low polarization dependence. Designed to accommodate both 980
nm and 1060 nm wavelengths, it ensures exceptional uniformity and stability across various coupling ratios, from
50/50 to 1/99.
Built to handle high optical power levels up to 300 mW, this coupler is ideal for demanding applications such as
Erbium-Doped Fiber Amplifiers (EDFAs) and Raman amplifiers. It boasts excellent environmental stability, operating
reliably over a temperature range from -5°C to +70°C. With customizable options for fiber types, connector types, and
coupling ratios, it provides flexibility to meet diverse application needs while maintaining high performance and durability.
Whether used in telecommunications or high-power optical systems, the GKER 980/1060 nm Singlemode Coupler
ensures efficient and consistent signal distribution.
