The Singlemode Broadband Coupler from GKER Photonics is engineered to deliver superior performance with low insertion loss and minimal polarization dependence across a wide wavelength range. This coupler is available in center wavelengths of 850, 1064, and 1310 nm, with a broad operational tolerance of ±100 nm, making it highly versatile for various optical applications.

It features precise coupling ratios ranging from 50/50 to 1/99, ensuring accurate and consistent power splitting and monitoring. The coupler exhibits excellent uniformity with a maximum variation of 6 dB for the 50/50 ratio, and very low excess loss, ranging from 0.25 dB to 0.15 dB depending on the coupling ratio. Its high thermal stability maintains performance with minimal deviation over a wide temperature range from -5°C to +70°C.

Built for reliability, the coupler supports up to 300 mW of continuous wave optical power and offers robust performance with a minimum return loss of 55 dB for 1 × 2 configurations and 60 dB for 2 × 2 configurations. This makes it ideal for demanding optical communication systems, telecommunications, and testing applications where precise signal routing and minimal signal loss are crucial.
