Boxphotonics offers a comprehensive range of high-performance optical passive components engineered for fiber optic communications, laser systems, sensing, and test & measurement applications. Our passive component portfolio includes optical isolator, optical circulator, fiber coupler, wavelength division multiplexers (WDM), polarization beam splitter/combiner, variable optical attenuator, and fiber polarization controllers - covering wavelengths from 780 nm to 2000 nm with both single-mode and polarization-maintaining fiber options.
High-isolation, low-insertion-loss devices available in 840 nm, 980 nm, 1064 nm, 1310nm, and 1550 nm bands. Supports both single-mode and polarization-maintaining fibers. It handles optical power up to 20 W.
3-port/ 4-port/ 5-port configurations with high isolation and low insertion loss. Available in both single-mode (SMF-28e) and polarization-maintaining (PM1550, PM980) fiber. Excellent for bidirectional signal routing on a single fiber in EDFA, FBG interrogation, and OTDR systems.
WDM couplers operating across 780-1550 nm. Available in 1x2, 2x2, and 3x3 configurations with split ratios from 1/99 to 50/50. Ideal for 980/1550 nm pump WDM, Raman coupler, and interferometric sensing applications.
Separates or combines orthogonal polarization states with a high extinction ratio and low insertion loss. Available in 1064 nm, 1310 nm, 1550 nm, and 2000nm bands. Widely used in fiber laser polarization beam combining, coherent detection front-ends, and fiber gyroscopes.
