| E2V0034-37-X1 electronic components OL592L, OL5492L LASER DIODES 1.55 mm Coaxial DFB Laser Module OL592L, OL5492L GENERAL DESCRIPTION The OL592L, and OL5492L are MQW structured, 1.55 mm coaxial DFB laser modules with single-mode fiber pigtails. Having a good side-mode suppression ratio and a wide operating temperature range, these devices are optimal light sources for high-capacity long-haul transmission systems. FEATURES * * * * * * Single-mode fiber output: Pf=1 mW Side mode suppression ratio: 30dB 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 OL592L, OL5492L PACKAGE DIMENSIONS (Unit: mm) * OL592L * OL5492L f6.8 f6.8 30.6 43.6 2-f2.2 1.5 13 4-f0.45 e 2 CASE LD w PD 6.4 r e r q w q 1 w r PD e r 7 12.7 17 q e f4 CASE LD w 4-f0.45 2-f2.4 8 12 16 7 q 2 2/4 13 4 26.6 LASER DIODES OL592L, OL5492L 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 (Ta=25C) 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 1530 30 -- -- -- -- 50 Typ. 20 -- 1550 -- -- -- 1.1 0.5 -- Max. 40 -- 1570 -- 0.5 0.5 1.5 20 -- Unit mA mW nm dB ns ns V nA mA 3/4 LASER DIODES OL592L, OL5492L TYPICAL CHARACTERISTICS * OL592L, OL5492L Fiber Output Power vs. Forward Current (Ta=25C) 2 1.6 Fiber Output Power Pf (mW) (Pf-Im) 1.2 (Pf-IF) 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 * OL592L, OL5492L Oscillation Spectrum (Ta=25C) 5 Relative Intensity (dB) -15 -35 -55 -75 1536.6 1546.6 Wavelength(nm) 1556.6 4/4 |
