MITSUBISHI (OPTICAL DEVICES) FU-319SPP-C6 InGaAs PD PREAMP MODULE FOR THE 1.31 µm AND 1.55 µm WAVELENGTH RANGE DESCRIPTION FU-319SPP-C6 is InGaAs pin photodiode module with GaAs preamplifier, designed for use in highspeed, long haul optical communication systems. The coaxial package contains an InGaAs pin photodiode coupled with single-mode fiber pigtail and GaAs preamplifier. FEATURES • High-sensitivity (-23dBm typ) • 5pin coaxial package • Selectable single power supply voltage (+5V or 5.2V). (InGaAs pin 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 PD Reverse voltage VPD PD Reverse current (CW) Ir PD Forward current (CW) If Power supply voltage Operating case temperature Storage temperature VDD Tc Tstg Conditions VSS=0V - Rating 20 4 2 Unit V mA mA VSS=0V - 0~7 -40~+85 -40~+85 V °C °C MITSUBISHI (OPTICAL DEVICES) FU-319SPP-C6 InGaAs PD PREAMP MODULE FOR THE 1.31 µm AND 1.55 µm WAVELENGTH RANGE ELECTRICAL/OPTICAL CHARACTERISTICS (Tc=25°C,λ=1.3µm,VDD=5V,VSS=0V unless otherwise noted) Parameter Symbol Test Conditions Limits Unit Min.
