1310-1550nm Singlemode Broadband Coupler
Description
The GKER Photonics Singlemode Broadband Coupler (GK-SBC Series) is a high-performance optical device engineered for precise signal splitting and monitoring in advanced fiber optic communication systems. Designed with low insertion loss and minimal polarization dependence, this coupler ensures reliable and efficient power distribution across a wide range of wavelengths, including 1310 nm and 1550 nm, with the option for custom wavelengths.
The GK-SBC Series stands out for its exceptional uniformity in coupling ratios, ranging from 1/99 to 50/50, making it ideal for applications requiring exact power control. Its high environmental stability and low polarization dependent loss (PDL) ensure consistent performance even in challenging conditions, while its robust construction allows it to withstand the rigors of demanding network environments.
With excellent return loss and directivity, the GK-SBC Series minimizes signal degradation and crosstalk, preserving the integrity of the optical signal. This makes it a perfect choice for use in various optical communication systems, including local area networks (LANs), fiber optic sensors, and test instruments. Whether for power monitoring, signal routing, or network testing, the GKER Photonics Singlemode Broadband Coupler offers the reliability and precision needed for today’s high-speed optical networks.
