| 1550nm InGaAsP strained MQW DFB-LD KLT-255544x, 2.5G DFB LD TO CAN Description KLT255454x is long wavelength distributed feedback(DFB) laser diode(LD) sources in TO-56 package with flat window or ball lens or aspherical lens cap. KLT255454x consists of an InGaAsP strained multi-quantum well(MQW) LD and an InGaAs PIN-PD for output monitoring. It operates at 1550nm wavelength band and with data rates of 2.5 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 1.55m band Operating temperature range from -20C to 85C Data rates of 2.5Gbps 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 Max Test Conditions Symbol Min Typ Parameter 15 9 CW mA Ith Threshold current 50 35 CW, Top = 85C Pf mW CW, kink free Rated output power 5 25 40 at rated Po=5mw Iop Operating current mA 60 80 at rated Po=5mw, Top=85C Vop 1.1 1.5 V Operating voltage at rated Po=5mw mW/mA CW,Po=5mW Slope efficiency 0.3 0.25 nm at rated Po=5mw c 1530 1550 1570 Center wavelength SMSR 30 40 dB at rated Po=5mw Side mode suppression ratio tr 0.1 0.3 ns 20 to 80%, I b = Ith Optical rise and fall time tf 0.1 0.3 ns 80 to 20%, I b = Ith Im 0.05 0.2 mA at rated Po=5mw , Vrp = 1V Monitor PD current Id 0.1 A Vrp = 10V Monitor PD dark current Ct 10 20 pF Vrp = 10V, 1MHz Monitor PD capacitance Note: The engineering spec can be revised without any previous notice. 1/2 For more information on other parts available, please visit our website: www.kodenshi.co.kr KODENSHI KOREA CORP. 513-5 Eoyang-Dong, Iksan, 570-210, Korea Rev.001 1550nm InGaAsP strained MQW DFB-LD KLT-255544x, 2.5G DFB LD TO CAN Outline Drawing (Aaspheric Lens type) Pin connections Pin config. pin no. 1 pin no. 2 pin no. 3 pin no. 4 4G case ground/LD anode LD cathode Monitor PD cathode Monitor PD anode 4S Case ground LD cathode Monitor PD anode LD anode/m-PD cathode 4R case ground/LD anode m-PD anode m-PD cathode LD cathode Ordering information KLT Device Type 1 : FP(BH) Wavelength 31 : 1310 nm 55 : 1550 nm 49 :1490nm Data Rate 0 : CW 3 : 622 Mbps 4 : 1.25 Gbps 5 : 2.5 Gbps Operating Temp. 0 : 0~50 1 : 0~70 2 : -20~70 3 : 0~85 4 : -20~85 5 : -40~85 Package type Pin Config.
