The Model 1014, 45 GHz InGaAs Fiber-Optic Biased Photodetector makes ultra high-speed measurements over 500-1630 nm easy. The self-contained module connects directly to test instruments like digital oscilloscopes, spectrum analyzers, and network analyzers for lightwave time- and frequency-domain measurements. They accept FC-fiber-optic inputs from your optical apparatus, eliminating the need for lossy and dispersive high-frequency coaxial cables. The internal housing of the high-speed models is specially designed to preserve the frequency response and phase to give true fidelity in your measurements. It has a FC single-mode input and Wiltron K electrical output.
