| 1550nm InGaAsP strained MQW FP-LD KLT-155454x, LD TO can (Aspheric lens) Description KLT-155454x series are long wavelength Fabry-Perot LD sources in TO-56 package with asp lens cap KLT-155454x series consist of an InGaAsP strained multi-quantum well(MQW) laser diode(LD) and an InGaAs PIN-PD for output monitoring. They operate at 1550 nm wavelength band and with various data rates from 155Mbps upto 1.25 Gbps. They are 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 aspheric lenses cap High reliability and environmental endurance Operating wavelength of 1.55 m band Wide operating temperature range from -40 to 85 Various data rates from 155Mbps upto 1.25Gbps APPLICATIONS SONET OC-1~ OC-48/SDH STM-1 ~ STM-16 l 125 Mbps, 622Mbps, and 1.25Gbps for ATM and Ethernet Suitable for fabrication of coaxial LD module, TOSA, and Bi-Di module Absolute Maximum Ratings Parameter Operating temperature Storage temperature Peak laser output power Peak reverse laser voltage Peak forward monitor PD current Peak reverse monitor PD voltage Symbol Top Tstg Po Vrl Ifp Vrp Min -40 -40 Max 85 85 18 2 2 10 unit mW V mA V Optical and Electrical Characteristics (KLT-155454x, Top = 25 Parameter Symbol Min Typ Top -40 Operating temperature Ith 4 8 Threshold current Iop 35 Operating current 0.2 0.3 Slope efficiency Vop 1.1 Operating voltage c 1530 1550 Center wavelength 2 RMS spectral width tr Optical rise and fall time tr Im 0.1 0.3 Monitor PD current Id Monitor PD dark current Cm 10 Monitor PD capacitance otherwise specified) Max Unit Test Conditions 85 20 mA CW, kink free 42 CW, Po=12mW CW, Po=12mW 1.5 V at rated Po = 12mw 1570 nm at rated Po = 12mw 5 nm at rated Po = 12mw 0.5 ns 20 to 80 %, Ib= Ith,Po =12mw 0.5 ns 80 to 20 %, Ib= Ith,Po =12mw mA at rated Po =12mw, Vrp=1V 1 A Vrp = 10V 20 pF Vrp = 10V, 1MHz 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 FP-LD KLT-155454x , LD TO can (Aspheric lens) Outline Drawing Pin connections Pin config. pin no. 1 pin no. 2 pin no. 3 pin no. 4 4S Case ground LD cathode m-PD anode LD anode/m-PD cathode 4G LD anode/case ground LD cathode Monitor PD cathode Monitor PD anode Ordering information KLT Device Type 1 : FP(BH) 2 : DFB Wavelength 31 : 1310 nm 55 : 1550 nm Data Rate 0 : CW Operating Temp.
