Product details
Overview
The FT-1064-8 is a polarization-maintaining fused fiber coupler for 1x2 and 2x2 layouts, offered at 1064, 1030 and 980 nm center wavelengths with ±15 nm bandwidth. Excess loss stays within 0.5 dB, the extinction ratio at 20 dB minimum and directivity at 50 dB minimum. Tap ratios run from 1/99 to 50/50 with stated tolerances, so monitoring taps and even splits stay within design margins. Continuous power handling reaches 3 W through PM Panda fiber. Two package styles cover bare fiber, 900 μm loose tube and 2/3 mm jacket builds across -5 to +75 °C.
