Product Description
3-Port Polarization-Insensitive Optical Circulator (1650nm) - Low Insertion Loss, High Isolation for Fiber Sensing, Monitoring, and Optical Communication
Product Overview:
This 3-port 1650nm polarization-insensitive optical circulator uses SMF-28e fiber and P-grade steel tubing for encapsulation. It features low insertion loss, high isolation, and high directivity, enabling stable optical signal transmission from P1 to P3. It is suitable for fiber optic systems with high requirements for reflection suppression, link isolation, and transmission reliability.
