Polarization-Maintaining Isolator (1310/155 nm)
The PM Isolator is a high-performance optical isolation device with operating wavelengths of 1310±15nm, 1550±15nm, and 1480±15nm. Available in single/dual stage and P/A grade configurations: Single-stage P-grade offers typical insertion loss of 0.4dB, and peak isolation of 42dB; dual-stage P-grade provides typical insertion loss of 0.5dB, and peak isolation of 58dB. Features a high extinction ratio (B type ≥20dB, F type ≥23dB),) and high return loss (≥55/50dB). Compliant with Telcordia GR-1209-CORE and GR-1221-CORE standards and RoHS certified. Compatible with SM13-PS-U25A or SM15-PS-U25A fiber, with a maximum input power of 500mW,. Operating temperature range: -5~+70°C; storage temperature range: -40~+85°C. Package dimensions: Φ5.5×L34mm.. Ideal for industrial CW fiber lasers, fiber sensing, communication systems, test equipment, and polarization-maintaining optical systems.
