The 1×2 1550nm PM FBT Splitter with Steel Tube is an optical power splitter designed to divide a single input fiber into two output fibers at a wavelength of 1550nm, commonly used in long-range telecommunications and fiber-optic networks. The PM (Polarization Maintaining) feature ensures that the polarization state of the signal is preserved, which is crucial for applications requiring high precision, such as in sensors or advanced telecom systems. It uses FBT (Fused Biconical Taper) technology, a cost-effective method for fiber splitting, offering reliable performance, though with slightly higher insertion losses compared to other technologies like PLC splitters. The splitter is housed in a steel tube, providing mechanical protection and durability, making it suitable for harsh environments. This device is ideal for signal distribution in telecommunications, test equipment, and polarization-sensitive sensing applications.
