1310nm Polarization Maintaining 3 Ports Optical Circulator
The 1310nm Polarization Maintaining 3-Port Optical Circulator is a high-performance non-reciprocal optical device designed to direct optical signals sequentially from Port 1 → Port 2 → Port 3 while preserving the input polarization state. Built with PM1300 polarization maintaining fiber, this circulator ensures excellent polarization stability, low insertion loss, and high isolation for precision optical systems.
Featuring a dual-stage structure, the device provides superior isolation performance (≥40 dB) and low insertion loss (≤0.9 dB), making it ideal for fiber optic communication, optical sensing, fiber laser systems, and other polarization-sensitive applications where stable signal routing is critical.
