High-Precision Polarization-Maintaining Beam Splitter/Combiner (PM PBS / PBC - 1×2)
GRACYFIBER's polarization-maintaining beam splitter/combiner (PM PBS/PBC) is a high-precision 1×2-port fiber optic device designed for efficient separation or combining of optical signals by controlling the polarization state of light, maintaining extremely stable polarization state transmission across all ports. Manufactured using precisely aligned, high-quality polarization-maintaining fiber (PM Fiber), this device comprehensively covers a broad wavelength range from 980 nm to 1620 nm. With extremely low insertion loss and excellent polarization extinction ratio (ER), it provides industrial-grade stability for erbium-doped fiber amplifier (EDFA) pumping, polarization multiplexing in coherent communication systems, and quantum optics research. Available in multiple performance grades (Grade P / Grade A) and flexible packaging options, this product is fully ready to meet deployment needs from cutting-edge laboratories to harsh industrial environments.

* Above specifications are for devices without the connectors.
* For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower.
* The PM fiber and the connector key are aligned to the slow axis. fast axis is blocked.
(Designed to solve your polarization crosstalk, high power pump loss, and system integration challenges)
Pain points/value addressed: In Grade P specifications at 1310/1480/1550 nm, the minimum polarization extinction ratio (ER) is 22 dB, and the maximum insertion loss is only 0.4 dB (Note: With connectors, insertion loss increases by 0.3 dB, and ER decreases by 2 dB). This extremely high polarization purity and low loss characteristics are crucial for quantum interference devices and fiber optic gyroscopes (FOGs), significantly improving the system's signal-to-noise ratio and eliminating measurement errors caused by polarization mode dispersion.
Pain points/value addressed: A single device design can function as a beam splitter (PBS) to separate orthogonally polarized light, or as a beam combiner (PBC) to seamlessly combine two orthogonally polarized beams. Supports 980, 1030, 1064, 1310, 1480, 1550 nm and broadband (1260~1620 nm) options. This provides high-power Raman and EDFA amplifier manufacturers with the optimal physical solution for perfectly superimposing the power of multiple pump lasers.
It features continuous optical power handling capability up to 300 mW, and high return loss and directivity of ≥ 50 dB (RL reduced by 5 dB with connectors). It supports stable operation in harsh environments ranging from -5°C to 65°C, ensuring long-term maintenance-free operation of outdoor LiDAR systems and specialized optical communication networks.
Pain Point Solved/Value Benefits: At the factory, polarization-maintaining fibers and connector keys are precisely aligned with the slow axis, while the fast axis is blocked. This standardized polarity control significantly simplifies the coupling and debugging process on coherent transceiver OEM production lines, improving assembly yield.
