4 Ports 1550nm Singlemode Polarization Insensitive Optical Circulator
The 4 Ports 1550nm Singlemode Polarization Insensitive Optical Circulator is a high-performance non-reciprocal passive optical device designed to control the direction of light transmission in singlemode fiber systems. It sequentially routes optical signals from Port 1 → Port 2 → Port 3 → Port 4 with minimal insertion loss and excellent isolation, ensuring reliable and efficient unidirectional signal flow without back reflection.
Operating at 1550 nm, the standard wavelength for optical communication, this circulator delivers low insertion loss, high return loss, and high isolation while remaining polarization insensitive, providing consistent performance regardless of input polarization state. With its compact and rugged construction, it offers excellent stability under varying environmental conditions.
The 4-port configuration makes it ideal for complex optical systems that require multiple channel routing and isolation, such as DWDM/CWDM networks, fiber amplifiers (EDFA/Raman), OTDR testing, interferometric sensing, and optical add/drop multiplexing.
