4 Ports 1480nm Singlemode Polarization Insensitive Optical Circulator

4 Ports 1480nm Singlemode Polarization Insensitive Optical Circulator

The 4 Ports 1480nm Singlemode Polarization Insensitive Optical Circulator is a high-performance non-reciprocal passive device designed to direct light sequentially from Port 1 → Port 2 → Port 3 → Port 4 with minimal insertion loss and high isolation. Operating at 1480 nm, it is optimized for FTTx, PON systems, and optical communication networks, where precise signal routing and low back reflection are essential.

Featuring a polarization-insensitive design, this circulator provides consistent optical performance regardless of the input polarization state. Its low insertion loss, high return loss, and compact construction ensure stable and reliable operation in demanding environments. The rugged design and precision optical alignment make it ideal for both laboratory testing and long-term deployment in network infrastructures.

Specifications

Note: Test environment: 25°C. Data shown exclude connectors. Adding connectors will increase insertion loss by 0.3dB and reduce return loss by 5dB.
