1310 nm OPTICAL FIBER COMMUNICATIONS InGaAsP STRAINED MQW-DFB LASER DIODE COAXIAL MODULE FOR 2.5 Gb/s NDL7620P SERIES FEATURES DESCRIPTION • PEAK EMISSION WAVELENGTH: λP = 1310 nm The NDL7620P Series is a 1310 nm λ/4-phase-shifted DFB (Distributed Feed-Back) laser diode coaxial module with internal optical isolator. Newly developed strained Multiple Quantum Well (st-MQW) structure is adopted to achieve stable dynamic single longitudinal mode operation over a wide temperature range of 0 to +70°C. It is designed for STM-16 applications. • HIGH SPEED RESPONSE: tr = 40 ps tf = 100 ps • INTERNAL OPTICAL ISOLATOR • InGaAs MONITOR PIN-PD • WIDE OPERATING TEMPERATURE RANGE: TC = 0 to +70°C • λ/4 - PHASE-SHIFTED DFB ELECTRO-OPTICAL CHARACTERISTICS (TC = 0 to +70 °C, unless otherwise specified) PART NUMBER PACKAGE OUTLINE SYMBOLS NDL7620P Series PARAMETERS AND CONDITIONS UNITS MIN V 0.9 mW 2.0 TYP VF Forward Voltage, Pf = 2 mW, TC = 25°C Pf Optical Output Power from Fiber, IF = ITH + 40 mA ITH Threshold Current mA ηd Differential Efficiency from Fiber, Pf = 2 mW W/A 0.05 Temperature Dependence of Differential Efficiency ηd (TC = 70° C) from Fiber, ∆ηd = 10 log ηd (TC = 25° C) dB -3.5 -2.5 Peak Emission Wavelength, Pf = 1 mW, Ib = ITH, 2.5 G/s-NRZ, PN 1/2 nm 1290 1310 Side Mode Suppression Ratio, Pf = 1 mW, Ib = ITH, 2.5 G/s-NRZ, PN 1/2 dB 30 40 tr Rise Time, 10-90%, Ib = 0.9 x Ith ps 40 125 200 ∆ηd λp SMSR 1.4 45 tf Fall Time, 90-10%, Ib = 0.9 X Ith ps 100 Im Monitor Current, VR = 5 V, Pf = 2 mW µA 50 ID Monitor Dark Current, VR = 5 V, TC = 25°C nA 0.5 Ct Monitor PD Terminal Capacitance, VR = 5 V pF 1.0 γ1 Tracking Error, Im = const. dB Note: 1. γ = 10 log MAX 1330 2000 5.0 1.5 1.0 Pf Pf 2mW (mW) TC = 25°C TC = 0 to +70°C 2 Pf 0 Im (at Pf (25°C) = 2 mW) Im California Eastern Laboratories NDL7620P SERIES ABSOLUTE MAXIMUM RATINGS1 (TC = 0 to +70 °C, unless otherwise specified) SYMBOLS PARAMETERS UNITS RATINGS 150 IF Forward Current of LD mA Pf Optical Output Power from Fiber mW 5.0 VR Reverse Voltage of LD V 2.0 10 IF Forward Current of PD mA VR Reverse Voltage of PD V 20 TC Operating Case Temperature °C 0 to +70 TSTG Storage Temperature °C -40 to +85 TSLD Lead Soldering Temperature (10 s) °C 260 Note: 1.
