DESCRIPTION
The Corning Lasertron QDFT pinFET module is a high-sensitivity detector and hybrid preamplifier module designed for fiber-optic receivers operating at data rates up to and exceeding 420 Mb/s at 1300 and 1550 nm wavelengths. The transimpedance circuitry provides excellent sensitivity and superior dynamic range. The high sensitivity results from use of an advanced GaInAs detector element having <10 nA leakage and a responsivity of >0.8 A/W at 1300 and 1550 nm. Sensitivities range from -53 dBm at 18 Mb/s, to -43 dBm at 140 Mb/s. Optical dynamic range exceeds 25 dB. Operation requires only +5 V power supplies at modest bias currents. TRANSIMPEDANCE DESIGN CIRCUITRY APPLICATIONS
The Corning Lasertron QDFT pinFET module consists of a low-capacitance, front-illuminated planar detector element followed by a hybrid transimpedance amplifier. Benefits of the transimpedance design of the QDFT pinFET module include excellent dynamic range and ease of implementation. Simply by applying +...
