Product Profile
The four-port fiber optic circulator is a compact, high-performance optical device. It simultaneously transmits the input signal from port 1 to port 2, a second signal from port 2 to port 3, and a third signal from port 3 to port 4 with very low insertion loss. The device has high isolation, low insertion loss, high extinction ratio and good environmental stability.
Optical circulator is a special optical fiber component, which has the function of single fiber bidirectional transmission. Combined with fiber grating and other reflection devices, it is widely used in DWDM system, high speed system and bidirectional communication system.

Product Features
Low Insertion Loss for Enhanced Signal Efficiency
The lower insertion loss of the 4 Port Fiber Optic Circulator allows itself to be utilized with lower signal attenuation, thus reducing the power requirements of the signal transmitter.
High Isolation for Effective Signal Separation
With a high isolation value(min. 38dB), this circulator ensures optimal signal separation within the device, preventing signal crosstalk and potential distortion so as to enhance overall signal integrity and system performance.
Exceptional Reliability in Challenging Environments
OPTICO's 4 Port Fiber Optic Circulator is engineered with a mature production process, guaranteeing high reliability even in harsh environmental conditions ranging from -0°C to +70°C.
Compliant with TelcordiaGR-1209 and GR-1221
Superior Performance and Design
Low Polarization Dependent Loss (PDL), ensuring consistent performance even under varying conditions (less than 0.2dB at 23°C).
Epoxy-free optical path, contributing to the device's longevity and stability.
Featuring a compact direct-plug encapsulation, the circulator is designed for ease of integration and installation.
