By leveraging Fused Biconically Tapered (FBT) wavelength flattening technology, Ultra Broadband Polarization Maintaining (PM) Fused Fiber Couplers/Splitters support operation over bandwidths up to ±50 nm for polarization maintaining fibers (including Panda and Bow-Tie). These products support builds of expanding global imaging and sensor markets utilizing broader wavelength bandpass with highest path-matching accuracy for optimal system performance.
