Polarization-Maintaining Isolator (1053 nm)
PM Isolator is a high-performance optical isolation device with a center wavelength of 1053±5nm, available in single-stage and dual-stage configurations. Single-stage P-grade models feature typical insertion loss of 2.2dB, and peak isolation of 40dB; dual-stage P-grade models offer typical insertion loss of 4.3dB, and peak isolation of 52dB. High extinction ratio (B type ≥20dB, F type ≥23dB),), high return loss (≥55/50dB). Compliant with Telcordia GR-1209-CORE and GR-1221-CORE standards; RoHS certified. HI1060 or other fiber types supported. Maximum input power: 300mW,. Operating temperature: -5~+50°C; storage temperature: -40~+85°C. Package size: Φ5.5×L34mm.. Widely used in industrial continuous-wave fiber lasers, fiber sensing, communication systems, test equipment, and polarization-maintaining optical systems.
