| STH91004X STH91005x Target Specification 1550nm DFB Laser in Coaxial Package with SM-Pigtail, High Power * * * * * * Designed for application in high-speed and long-haul fiber-optic networks Laser Diode with Multi-Quantum-Well and gain coupled structure Suitable for bit rates up to 622 Mbit/s (STM-4) without thermoelectric cooler and optical isolator 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. These are absolute stress ratings only. Values above maximum ratings can cause permanent damage to the device.
