Polarization-Maintaining Tap Isolator WDM (2X2-T15R98 & T15R14)
PM Tap Isolator WDM combines isolator, tap coupling, and wavelength division multiplexing in a 2×2 port configuration, available in single-stage or dual-stage modes. Signal wavelength range: 1550±2 nm; passband insertion loss: 1.1–4.3 dB (tap ratio dependent); isolation ≥30 dB (single stage) / ≥48 dB (dual stage). Pump wavelength ranges: 980±2 nm and 1480±2 nm; reflection band insertion loss ≤0.6dB.. Supports multiple tap ratios (1/99, 2/98, 5/95, 10/90, 50/50); extinction ratio ≥22 dB (Type B) / ≥20 dB (Type F); return loss ≥50 dB; thermal stability ≤0.005dB/°C. Compliant with Telcordia GR-1209-CORE and GR-1221-CORE standards; RoHS certified. Uses 1550 Panda fiber for input/output ports and SM-28e fiber for the tap port. Max power rating: 500mW,; operating temperature: -5 to +70°C; package size: Φ5.5×34/35/38 mm. Widely used in industrial CW fiber lasers, fiber sensing, communication systems, test equipment, and polarization-maintaining optical systems.
