1500 nm OPTICAL FIBER COMMUNICATIONS InGaAsP MQW-DFB LASER DIODE COAXIAL MODULE NDL7705P SERIES FEATURES DESCRIPTION • PEAK EMISSION WAVELENGTH: λP = 1550 nm The NDL7705P Series is a 1550 nm phase-shifted DFB (Distributed Feed-Back) laser diode module with optical isolator. Newly developed strained Multiple Quantum Well (MQW) structure is adopted to achieve stable dynamic single longitudinal mode operation over a wide temperature range of -40 to +85°C. It is designed for all STM-1and STM-4 applications. • OPTICAL OUTPUT POWER: Pf = 2.0 mW • INTERNAL OPTICAL ISOLATOR • InGaAs MONITOR PIN-PD • WIDE OPERATING TEMPERATURE RANGE: TC = -40 to +85°C • λ/4 - PHASE-SHIFTED DFB ELECTRO-OPTICAL CHARACTERISTICS (TC = -40 to +85°C, unless otherwise specified) PART NUMBER PACKAGE OUTLINE SYMBOLS NDL7705P Series UNITS MIN VF Forward Voltage, IF = 30 mA V 0.9 ITH Threshold Current, TC = 25˚C TC = 85˚C mA ηd Differential Efficiency from Fiber, TC = 25˚C TC = 85˚C W/A 0.070 0.035 0.120 0.075 ∆ηd Temperature Dependence of Differential Efficiency from Fiber, ∆ηd = 10 log ηd (TC = 85° C) ηd (TC = 25° C) dB -3 -2 Peak Emission Wavelength, Pf = 1 mW nm 1530 1550 Side Mode Suppression Ratio, Pf = 1 mW dB 30 λp SMSR PARAMETERS AND CONDITIONS tr Rise Time, Ib = 0.9 x Ith ns tf Fall Time, Ib = 0.9 X Ith ns Im Monitor Current, VR = 5 V, Pf = 2 mW µA ID Monitor Dark Current, VR = 5 V, TC = 25°C nA γ1 Tracking Error, Im = const.(Pf = 2 mW, TC = 25˚C) dB RIN Relative Intensity Noise, Ref = -14 dB, Pf = 1 mW dB/Hz TYP MAX 1.3 15 35 50 1570 0.5 0.5 300 2500 0.1 5 1.0 -140 -130 Note: 1. γ = 10 log Pf 2 mW Pf TC = 25°C (mW) TC = -40 to +85°C 2 Pf 0 Im Im (at Pf (25°C) = 2 mW) California Eastern Laboratories NDL7705P SERIES ABSOLUTE MAXIMUM RATINGS1 (TC = 25°C, unless otherwise specified) SYMBOLS PARAMETERS UNITS RATINGS IF Forward Current of LD mA ITH+50 Pf Optical Output Power mW 5.0 VR Reverse Voltage of LD V 2.0 2.0 IF Forward Current of PD mA VR Reverse Voltage of PD V 15 TC Operating Case Temperature °C -40 to +85 TSTG Storage Temperature °C -40 to +85 TSLD Lead Soldering Temperature (10 s) °C 260 Note: 1.
