1528-1610nm C+L Band Polarization Maintaining 3 Ports Optical Circulator
The 1528–1610nm C+L Band Polarization Maintaining 3-Port Optical Circulator is a high-performance non-reciprocal optical device designed for broadband signal routing in polarization-sensitive optical systems. It directs optical signals sequentially from Port 1 → Port 2 → Port 3 while maintaining the input polarization state, ensuring stable transmission and excellent system reliability.
Built with PM1550 polarization maintaining fiber and featuring a dual-stage design, this circulator delivers high isolation (≥40 dB), low insertion loss (≤0.9 dB), and excellent extinction ratio across the full C+L telecom band. It is ideal for DWDM systems, coherent communication, fiber amplifiers, optical sensing, and high-performance fiber laser applications requiring stable polarization control over a wide wavelength range.
