3 Ports 1310nm High Power Polarization Insensitive Optical Circulator

3 Ports 1310nm High Power Polarization Insensitive Optical Circulator

The 3 Ports 1310nm High Power Polarization Insensitive Optical Circulator is a high-performance, non-reciprocal passive optical device designed to direct light sequentially from Port 1 → Port 2 and Port 2 → Port 3, ensuring precise and stable unidirectional signal transmission. Operating at 1310 nm, this circulator provides low insertion loss, high isolation, high return loss, and excellent thermal stability, making it ideal for high-power optical communication, testing, and sensing systems.

Featuring a polarization-insensitive design, it maintains consistent performance regardless of input polarization, ensuring reliable operation in both continuous-wave (CW) and pulsed applications. The circulator is built using LMA-GDF-10/125-M fiber, optimized for the 1310 nm O-band, ensuring true singlemode transmission and minimal back reflection under high-power operation.

Engineered with advanced optical coating and precision alignment, this device supports high CW power levels with excellent environmental and long-term stability. It is widely used in high-power optical transmission systems, OTDR testing, fiber amplifiers, interferometric setups, and optical measurement equipment.
