Polarization-Maintaining Circulator (2X2-1310/1550 nm)
The PM Circulator enables unidirectional light transmission from Port 1 → Port 2 → Port 3 → Port 4 in a four-port configuration. It supports center wavelengths of 1310±20 nm or 1550±20 nm and is available in single-stage and dual-stage versions. The dual-stage model offers typical insertion loss of 0.8dB, and peak isolation of 55 dB; the single-stage model provides typical insertion loss of 0.7dB, and peak isolation of 40 dB. Features include a high extinction ratio (≥20dB),), high return loss (≥55dB),), and low crosstalk (≥50dB).). Compliant with Telcordia GR-1209-CORE and GR-1221-CORE standards, RoHS certified. Designed for SM13-PS-U25A or SM15-PS-U25A fiber, with max power of 500mW,. Operating temperature range: -5~+70°C. Package dimensions: Φ5.5×34/35/38 mm. Ideal for industrial CW fiber lasers, fiber sensing, communication systems, test equipment, and polarization-maintaining optical systems.
