FRM5W231KT

InGaAs-APD/Preamp Receiver FEATURES Data rate up to 2.5Gb/s -32dBm typ. sensitivity 30µm active area APD chip with GaAs preamplifier Small co-axial package with single mode fiber FRM5W231KT/LT KT APPLICATIONS High bit rate long haul optical transmission systems operating at 2.5Gb/s LT DESCRIPTION These APD preamplifiers use an InGaAs APD chip with GaAs IC preamplifier. The KT package is designed for a horizontal PC board mount. The LT package is secured by a vertical flange. Each package is connected with single mode fiber by Nd: YAG welding. The detector preamplifier is DC coupled and has a low electrical output when the APD is illuminated. www.DataSheet4U.com Edition 1.0 March 1999 1 FRM5W231KT/LT Parameter Storage Temperature Operating Temperature Supply Voltage APD Reverse Voltage APD Reverse Current Symbol Tstg Top Vss VR (Note 1) IR (Note 2) InGaAs-APD/Preamp Receiver ABSOLUTE MAXIMUM RATINGS (Tc=25°C, unless otherwise specified) Ratings -40 to +85 -40 to +85 -7 to 0 0 to VB 0.6 Unit °C °C V V mA OPTICAL & ELECTRICAL CHARACTERISTICS (Tc=25°C, λ=1,310/1,550nm, Vss=-5.2V, unless otherwise specified) Parameter APD Responsivity APD Breakdown Voltage Temperature Coefficient of VB Symbol R15 R13 VB γ Test Conditions 1,550nm, M=1 1,310nm, M=1 ID=10µA Note 3 AC-Coupled, f=100MHz, RL=50Ω, Pin <-20dBm, AC-Coupled, RL=50Ω, M=3 to 15, -3dBm from 1MHz AC-Coupled, RL=50Ω, Average within BW 2.488Gb/s NRZ, PRBS=223-1, B.E.R.=10-10, VR is set at optimum value Tc=-40 ...
