SLD-CBX1WAO-XX-XCWDM MQW-DFB Laser Diode Module DescriptionDLD-C48X Series are InGaAsP/InP MQW-DFB laser diode modules，designed for fiber optic communication systems. These modules are ideally suitable for long reach and intermediate reach of 622Mb/s and 2.5Gb/s transmission applications. A laser diode is mounted into a coaxial package integrated with an InGaAs monitor PD. Especially DLD-C48X Series have a single-stage optical isolator integrated inside.  Features             ● Economical uncooled lasers             ● Data rate up to 2.5Gbps             ● low threshold current             ● Designed to meet Telcordia (Bellcore)               and ITU-T requirements              ● nGaAsP/InP, SMQW lasers             ● Multiple package types available                                                                 Applications● SONET OC-48/SDH STM-16        ● Long-haul transmission systems   Electrical and optical characteristics (Pf=1mW, Tc=+25°C, unless otherwise noted.) ParameterSymbolMin.Typ.Max.UnitNoteThreshold currentIth+1015mACw  50Cw,Tc=0℃~70℃Optical output powerPf11.5 mWCW, If=Ith+20mA 0.7  CW, If=Ith+20mA, Tc=0℃~+70℃Slope efficiencySe0.050.075 mW/mACW, If=Ith+20mA0.035  CW, If=Ith+20mA, Tc=0℃~+70℃Tracking Error?Pf-1 1dBIm hold(@Pf=2mW(+25℃),cw, Tc=0℃~70℃Central wavelengthλc1470 1610nmITU-T G.694.2 20nm gridCentral wavelength accuracydλ-3 3nmTc=25℃Central wavelength drift with case temperaturedλc/dTc 0.10.12nm/°CAverageSide mode suppression ratioSMSR30  dBTc=0℃~70℃Spectral width(-20dB)?λ-20  1nmTc=0℃~70℃Monitor  currentIM100 1000uAPf=CW, PavgDark currentID  0.1uA Rise timetr 0.10.15nsIb=Ith,20%~80%, Tc=0℃~70℃
