Description
The GKER Photonics 2 × 2 Polarization Beam Combiner/Splitter (GK-DPBC/DPBS Series) is a high-performance optical component engineered to efficiently combine or separate two orthogonal polarization signals. This compact device is critical in applications such as polarization mode dispersion compensation, erbium-doped fiber amplifiers (EDFA), Raman amplifiers, coherent telecommunication systems, and fiber sensors. The GK-DPBC/DPBS Series is characterized by its low insertion loss and high extinction ratio, ensuring optimal performance and minimal signal degradation.
Designed for the 1550 nm wavelength range, this combiner/splitter is available in two grades: Premium (P) and Standard (A), offering flexibility depending on the application requirements. The device features a minimal insertion loss of 0.6 dB (typical) and a high extinction ratio of up to 20 dB for the splitter configuration, making it ideal for use in high-precision environments where signal integrity is paramount.
The combiner/splitter is compatible with both SMF-28 and PM1550 Panda fibers, and can handle continuous wave optical power up to 5 W and peak power up to 10 kW for nanosecond pulses. Its robust design allows for reliable operation across a wide temperature range, from -5°C to +70°C, with storage capability down to -40°C.
Whether used in advanced telecommunication systems or high-power laser applications, the GKER Photonics 2 × 2 Polarization Beam Combiner/Splitter delivers outstanding performance and reliability.
