The BCP/JDSU Uniphase 320A is an optical-to-electrical receiver that converts low-level optical signals into high-gain electrical outputs for fiber optic communications and test applications. Built around an InGaAs APD detector, it delivers minimum 2000 V/W conversion gain across a DC to 2.5 GHz bandwidth, with typical performance reaching 3.0 GHz and 2500 V/W. The receiver detects signals as low as 100 nW (-40 dBm) and handles high-power inputs up to 1.0 mW (0 dBm) without overload, making it ideal for transmitter waveform analysis and error rate testing on high-speed digital signals.
