1550nm DFB Pigtail Laser Diode Module
Product Description
Product Detail
1. Summary of 1550nm DFB Pigtail Laser Diode Module
The 1550nm DFB Pigtail Laser Diode Module consists of Distributed Feedback (DFB) lasers, having a fiber pigtail precisely attached for optimum coupling efficiency. This 1550nm center wavelength version has a typical 1mW~4mW of output power and includes a back facet photodiode, and an integrated optical isolator. The 9/125 single mode fiber pigtail is terminated with an FC/APC or FC/PC style fiber optic connector. Applications include high-speed data and telecommunications systems and instrumentation, and optical instruments requiring a laser diode light source.
