| E2V0029-37-X1 electronic components OL392L, OL3492L LASER DIODES 1.3 mm Coaxial DFB Laser Module OL392L, OL3492L GENERAL DESCRIPTION The OL392L, and OL3492L are 1.3 mm coaxial DFB laser modules with single-mode fiber pigtails. Having good side-mode suppression ratio in a wide operation temperature range, these devices are optimal light sources for high-capacity long-haul optical transmission systems. FEATURES * * * * * * Single-mode fiber output: Pf=1 mW Side mode suppression ratio: 30 dB Includes monitor PD for power control Built-in optical isolator Wide operation temperature range Multi-quantum-well (MQW) structure APPLICATIONS * Optical transmission systems * Optical subscriber loops * Optical measurement systems 1/4 LASER DIODES OL392L, OL3492L PACKAGE DIMENSIONS (Unit: mm) * OL392L * OL3492L f6.8 f6.8 30.6 43.6 2-f2.2 1.5 13 4-f0.45 e 2 CASE LD w PD r e e q r 7 12.7 17 f4 4-f0.45 7 6.4 2-f2.4 8 12 16 w q r q CASE LD w q 1 w 2 r PD e 2/4 13 4 26.6 LASER DIODES OL392L, OL3492L ABSOLUTE MAXIMUM RATINGS Parameter Fiber Output LD Forward Current PD Reverse Voltage PD Forward Current Operating Temperature Storage Temperature Symbol Pf IF (LD) VR (PD) IF (PD) Topr Tstg -- -- Ta=25C Test Conditions Ratings 2 150 20 10 0 to +65 -40 to +85 Unit mW mA V mA C C OPTICAL AND ELECTRICAL CHARACTERISTICS Parameter Threshold Current Fiber Output Power Peak Wavelength Side Mode Suppresion Ratio Rise Time Fall Time Forward Voltage PD Dark Current Monitor Current Symbol Test Conditions Ith Pf lp SMSR tr tf VF IDARK Im -- IF=Ith+20 mA Pf=1 mW Pf=1 mW Ibias=Ith Pf=1 mW, 10% to 90% Pf=1 mW VR(PD)=5 V VR(PD)=5 V, Pf=1 mW Min. -- 1 1280 30 -- -- -- -- 70 Typ. 20 -- 1310 -- -- -- 1.1 0.5 -- Max. 40 -- 1340 -- 0.5 0.5 1.5 20 -- (Ta=25C) Unit mA mW nm dB ns ns V nA mA 3/4 LASER DIODES OL392L, OL3492L TYPICAL CHARACTERISTICS * OL392L, OL3492L Fiber Output Power vs. Forward Current (Ta=25C) 2.0 (Pf-Im) (Pf-IF) 1.6 Fiber Output Power Pf (mW) 1.2 0.8 0.4 0 0 20 40 60 80 Forward Current IF (mA) 100 0 1 2 3 4 Monitor Current Im (mA) 5 * OL392L, OL3492L Oscillation Specturm (Ta=25C) 5 Relative Intensity (dB) -15 -35 -55 -75 1305.2 1315.2 Wavelength(nm) 1320.2 4/4 |
