1528-1610nm C+L Band Single Mode 3 Ports Optical Circulator
The 1528–1610nm C+L Band Single Mode 3 Ports Optical Circulator is a broadband non-reciprocal passive device designed to route optical signals sequentially from Port 1 → Port 2 → Port 3 with high isolation and low insertion loss across an extended wavelength range.
Covering both the C-band and L-band, this circulator enables stable and efficient signal routing in modern dense wavelength division multiplexing (DWDM) systems and broadband optical networks. Compared to single-wavelength circulators, the C+L band version provides greater flexibility for multi-channel transmission and future network expansion.
It features low polarization dependent loss, high return loss, and excellent crosstalk suppression, ensuring reliable performance across the entire 1528–1610 nm wavelength range. Built with SMF-28e fiber, it is fully compatible with standard telecom infrastructure and suitable for high-capacity optical communication systems.
