1550nm Single Mode 3 Ports Optical Circulator
The 1550nm Single Mode 3 Ports Optical Circulator is a non-reciprocal passive device designed to route optical signals sequentially from Port 1 → Port 2 → Port 3 with high isolation and low insertion loss. Operating in the C-band around 1550 nm, it is optimized for fiber optic communication systems requiring stable signal routing and minimal back-reflection.
This circulator features low polarization dependent loss, high return loss, and excellent crosstalk suppression, ensuring reliable performance in dense wavelength division multiplexing (DWDM), optical amplifiers, and fiber sensing systems. It is built with SMF-28e fiber for standard telecom compatibility and supports stable operation across a wide temperature range.
