ML-T-1550-FP-2G51550 nm

ML-T-1550-FP-2G51550 nm FP Laser Diode for 1.25 Gb/s and 2.5 Gb/sOverviewModulight's ML-1550-T-FP-2G5 series are high-performanceFabry-Pérot (FP) laser diodes in 5.6 mm TOcans.The lasers emit single transverse mode at 1550nm wavelength. The can package includes an InGaAsmonitor photodiode for feedback loop.ML-1550-T-FP-2G5 series have been designed fordigital optical communication networks with up to 2.5Gb/s modulation speeds. Products are available withflat window cap or with ball lens cap for higher singlemodefiber coupling efficiency.Electro-Optical Characteristics 1,2Parameter Symbol Min Typ Max Unit Test ConditionRated optical power 3 PR 5 - - mW -40-85°CThreshold current 4 Ith - 10 15 mA 25°C- 23 - 85°COperating current Iop - 28 [30] 35 [42] mA 25°C, Pop=5 mW- 48 [52] - 85°C, Pop=5 mWOperating voltage Vop - 1.15 1.5 V -40-85°C, Pop=5 mWSerial resistance 5 Rs - 8 - Ω 25°C, Pop=5 mWSlope efficiency 5 η 0.22 [0.2] 0.29 [0.25] - W/A 25°C, Pop=5 mW- 0.19 [0.16] - 85°C, Pop=5 mWCentral wavelength λc 1530 1550 1570 nm 25°C, Pop=5 mW1485 - 1610 -40-85°C, Pop=5 mWSpectral width 6 ∆λ - 1.3 2.5 nm 25°C, Pop=5 mWTemperature shift of wavelength ∂λ/∂T - 0.65 - nm/K -40-85°C, Pop=5 mWPerpendicular beam θ⊥ - 44 [10] - deg 25°C, Pop=5 mWdivergence angle (FWHM) 7Parallel beam divergence θ|| - 23 [10] - deg 25°C, Pop=5 mWangle (FWHM) 7Modulation bandwidth f-3dB 6 - - GHz 25°C, Iop=Ith+16 mA4 - - 85°C, Iop=Ith+16 mAMonitor current Im 150 [200] 300 [400] 600 [700] µA 25°C, Pop=5 mWMonitor dark current Id - 0.1 1.0 µA 25°C ,VRPD=5 VMonitor capacitance Cm - 5 10 pF f=1 MHz, VRPD=5 VTracking error γ -1 - 1 dB Im=constant,Po=5mW@25°CFocal length 8 Df [5.87] mm 25°C, Pop=5 mWFiber coupling efficiency [10.3] % Single-mode fiberNote 1: All temperatures refer to case temperature, Tc, Note 2: Where indicated, values in brackets [ ] apply for ball lens captype , Note 3: Kink-free, demonstrated reliability, Note 4: 2nd derivative method, Note 5: PLO=1 mW, PHI,=3 mW, Note 6:RMS, -20 dB, Note 7: Full Width at Half Maximum, Note 8: Distance from reference plane (see mechanical specification) tofocal point.
