The 2 × 2 Dual Polarization Beam Combiner/Splitter from GKER Photonics is a high-performance optical component designed for combining or splitting two orthogonal polarization signals into one or two output fibers. This device excels in applications requiring precise signal management and high reliability, such as polarization mode dispersion compensators, Erbium-Doped Fiber Amplifiers (EDFAs), Raman Amplifiers, coherent telecommunication systems, and fiber sensors.

Featuring an exceptional combination of high extinction ratio and low insertion loss, the GK-DPBC/DPBS Series ensures optimal performance in demanding optical environments. The component operates efficiently at a center wavelength of 1550 nm, with a typical insertion loss of 0.6 dB for Grade P and 0.8 dB for Grade A, making it suitable for high-power and high-precision applications. The device supports up to 5 W of continuous wave optical power and can handle peak power up to 10 kW for nanosecond pulses.

The Polarization Beam Combiner/Splitter is engineered with advanced fiber technology, using PM1550 Panda Fiber for Ports 1 & 2, and either SMF-28 or PM1550 Panda Fiber for Ports 3 & 4. It provides a minimum extinction ratio of 20 dB for Grade P and 18 dB for Grade A, ensuring minimal signal degradation. Additionally, the device offers excellent directivity and return loss characteristics, with directivity reaching up to 50 dB and return loss up to 50 dB. Its robust design withstands a maximum tensile load of 5 N and operates within a temperature range from -5°C to +70°C, with storage capabilities extending from -40°C to +85°C.

The GK-DPBC/DPBS Series is available in various configurations to meet specific application needs, including different connector types, fiber jackets, and fiber lengths. This versatility makes it a valuable component in both standard and custom optical setups.
