Transcription

1 Txxxx Series 110nm/1550nm InGaAsP DFB Laser with Optical Isolator SMQW Structure SMF Pigtailed, SC or FC Connector 2.5Gbps Transmission Family Model Tx20x Tx0x T0x Features 1.µm/1.55µm InGaAsP SMQW DFB laser diode Low threshold, high slope efficiency High output power uncooled laser diode Operating temperature ; 0 to +70 / -20 to +85 Single-mode fiber pigtailed with SC or FC connector Tested by TERADIAN s Reliability and Qualification Program Description The Txxxx series, pigtailed coaxial module consists of an uncooled, reliable strained MQW InGaAsP laser(dfb) and a back-facet InGaAs PIN photodiode. The parts of pigtailed module single-mode fiber, lens and laser diode - are actively aligned by high power YAG laser welding method. This packaging guarantees high coupling efficiency, high slope efficiency, low operating current and low tracking error over a wide temperature range (0 to +70 /-20 to +85 ), and provides high optical performance for ITU-T G.652 standard optical fiber. Applications Used in telecommunication and data communication systems, from medium to high speed for intra-office, short-haul inter-office and long-haul inter-office applications. Fiber in the loop(ftto, FTTC, FTTH etc.) Intra-office and Inter-office links Transport links (SDH,SONET, PDH) Private optical networks Subscriber loops Teradian Inc. - 1 / 5 - DS-T020-Rev01

3 ! Handling Caution The module can be damaged by overvoltage and current surges. Precautions should be taken for transient power supply. This device is susceptible to damage as a result of electrostatic discharge(esd). Take proper precautions during both handling and testing The stress to the fiber pigtail may cause the damage on the performance. The fiber pigtail may snap off by dropping the module. Laser Eye Safety These modules have laser semiconductor product and are classified as AEL Class IIIb per U.S. FDA/CDRH 21CFR 100 and class a per EN These products comply with 21CFR, Chapter 1, Subchapter J( 21CFR and laser safety requirements). Laser Data Wavelength : nm(model : ) / nm(model : ) Measured Output power : mw(110nm) / mw(1550nm) Limited Power : mw(110nm) / nw(1550nm) Caution On operation, If optical connectors are unterminated, modules can emit invisible laser radiation. Radiation emitted by laser devices can be dangerous to the eyes. Avoided eye or skin exposure to direct or scattered radiation Ref : IEC60825 Laser emission Teradian Inc. - / 5 - DS-T020-Rev01
