| SEH61008X Target Specification 1300nm DFB Laser in Coaxial Package with SM-Pigtail, High Power, with optical Isolator for 2,5GBit Application and adaption board to Butterfly footprint Designed for application in high-speed and long haule fiber-optic networks Laser Diode with Multi-Quantum-Well and gain coupled structure Suitable for bit rates up to 2,5 Gbit/s (STM-16) with optical isolator, without cooler Ternary photodiode at rear mirror for monitoring and control of radiant power Hermetically sealed subcomponent, similar to TO 18 SM Pigtail with optional flange. Maximum Ratings Output power ratings refer to the SM fiber output. The operating temperature of the submount is identical to the case temperature Module Operating Temperature range at case Storage Temperature range Soldering Temperature tmax = 10 s, 2 mm distance from bottom edge of case Symbol TC Tstg TS Values 0... +70 - 40... +85 260 Unit C C C Laserdiode Direct forward current Radiant power CW Reverse Voltage Symbol IF max Values 120 4 2 Unit mA mW V e VR max Monitor Diode Reverse Voltage Symbol VR max Values 10 Unit V Siemens Aktiengesellschaft page 1/4 12/97 SEH61008X Characteristics All optical data refer to a coupled 10/125 nm SM fiber, Tc =25C.
