1260-1620nm O/C/L SM PM1550 1.8 mm(OD) Fiber Collimator with FC/APC for Optical Communication
Fiber Collimator
AIMLASER’s 1260–1620nm SM PM Fiber Collimator is designed for precise beam collimation in polarization-sensitive optical systems. Built with PM1550 Panda fiber and a compact 1.8mm OD lens package, it delivers low insertion loss, high extinction ratio, and tight beam alignment with an extremely small beam size of ≤0.5mm—ideal for O, C, and L-band fiber optic communication, including commonly used wavelengths such as 1310nm and 1550nm.
This fiber collimator supports customizable working distances from 5mm to 60mm and features an FC/APC connector for low back reflection, making it suitable for coherent and high-speed optical systems. With stable polarization performance, compact integration, and long operational life, it’s well-suited for applications in optical sensing, interferometry, and advanced photonics research.
Whether used in DWDM systems, optical coherence tomography, or interferometric sensors, this fiber collimator enables high-efficiency light transmission and excellent alignment precision—critical for today's high-speed, high-fidelity optical networks.
