MITSUBISHI (OPTICAL DEVICES) FU-319SPA-C6 InGaAs APD PREAMP MODULE FOR THE 1.31 µm AND 1.55 µm WAVELENGTH RANGE DESCRIPTION FU-319SPP-C6 is InGaAs avalanche photodiode module with GaAs preamplifier, designed for use in high-speed, long haul optical communication systems. The coaxial package contains InGaAs avalanche photodiode coupled with single-mode fiber pigtail and GaAs preamplifier. FEATURES • High-sensitivity (-33dBm typ) • 5pin coaxial package • Selectable single power supply voltage (+5V or 5.2V). (InGaAs avalanche photodiode and GaAs preamplifier are isolated from the case.) • GaAs preamplifier with AGC function • Differential output (50Ω ) APPLICATION 2.5Gbps.optical receiver (OC-48, STM-16) Extended reach datacom and telecom applications Long haul optical communication systems ABSOLUTE MAXIMUM RATINGS (Tc=25°C) Parameter Symbol Conditions Rating APD Reverse voltage VPD VSS=0V 0~Vbr APD Reverse current (CW) Ir 500 APD Forward current (CW) If 2 Power supply voltage VDD VSS=0V 0~7 Operating case temperature Tc -40~+85 Storage temperature Tstg -40~+85 Vbr: APD breakdown voltage.
