The J744 is a compact, wideband DC to 1GHz analog optical to electrical fiber optic converter. Typical OE conversion gain is 500mV/mW into 50 ohms, or 1V/mW into Hi-Z loads. GaAs and InGaAs versions are available, covering 700nm-875nm multimode and 1100nm-1650nm singlemode optical signals, respectively. A choice of ST or FC fiberoptic connector is also available.
