3-port 850nm980nm circulator

The 3-Port 850nm/980nm Circulator is a cost-effective and reliable optical component designed for applications requiring low insertion loss and stable signal routing. Operating at wavelengths of 850±20 nm and 980±20 nm, it features typical insertion loss of 1.3 dB and high isolation of up to 25 dB. With low polarization-dependent loss (≤0.2 dB) and high return loss (≥50 dB), this circulator ensures efficient performance in optical amplifiers, pump laser sources, fiber optic sensors, and test instrumentation. Available in compact package sizes (Φ5.5×L38 or L50) with bare fiber or 900µm loose tube options, multiple connector types, and various fiber lengths for flexible integration.
