| 1490nm InGaAsP strained MQW DFB LD for 1.25G TO CAN KLT-249414x Rev.001 Description KLT-2494414x is long wavelength distributed feedback(DFB) laser diode(LD) sources in TO-56 package with flat window or ball lens or aspherical lens cap. KLT-249414x consists of an InGaAsP strained multi-quantum well(MQW) LD and an InGaAs PIN-PD for output monitoring. It operates at 1490nm wavelength band and with data rates of 1.25 Gbps. It is suitable for fabricating pigtailed LD source, TOSA(transmitter optical sub assembly), and bi-directional module. FEATURES High performance strained MQW InGaAsP LD with BH(buried hetero-junction) structure Hermetically sealed TO-56 package with flat window or ball lens or aspherical lens cap High reliability and environmental endurance Operating wavelength of 1.49m band Operating temperature range from -20C to 85C Data rates of 1.25Gbps APPLICATIONS SONET OC-24/SDH STM-8 1.25Gbps Gigabit Ethernet Suitable for fabrication of coaxial LD module, TOSA, and Bi-Di module Absolute Maximum Ratings Parameter Operating temperature Storage temperature Peak laser forward current Peak laser reverse voltage Peak forward monitor PD current Peak reverse monitor PD voltage Symbol Top Tstg If Vrl Ifp Vrp Min -20 -40 Max 85 100 150 2 2 10 unit o C o C mA V mA V Optical and Electrical Characteristics (Top = 25C otherwise specified) Unit Symbol Min Typ Parameter Max 15 8 mA Ith Threshold current 30 50 Pf mW Rated output power 5 40 25 Iop mA Operating current 80 60 Vop V 1.1 1.5 Operating voltage mW/mA 0.20 0.28 Slope efficiency nm c 1487 1490 1493 Center wavelength dB 40 SMSR 30 Side mode suppression ratio tr 0.1 0.2 ns Optical rise and fall time tf 0.1 0.2 ns Im mA 0.2 0.05 Monitor PD current Id A 0.1 Monitor PD dark current Ct pF 10 20 Monitor PD capacitance Note: The engineering spec can be revised without any previous notice.
