Description
SG FusionChip Technology Co., Ltd presents the Narrow Line width DFB Butterfly Device, model SGNLD-xxxx-xx-xx-xx-14-xx-x. This high-quality Multi-Quantum Well (MQW) Distributed Feedback (DFB) laser diode is designed to meet the demanding requirements of high-power optical transmitter systems. Encased in a robust butterfly package, this device ensures reliable performance across diverse environments.
The integrated thermo-electric cooler (TEC) is a standout feature, enabling the laser diode to maintain optimal functionality in varying temperature conditions. This capability ensures the device operates efficiently between -20°C and +70°C, making it suitable for a wide range of applications. The single-mode or polarization-maintaining (PM) fiber pigtail enhances the device's versatility, allowing for precise optical signal transmission.
The sophisticated design of the SGNLD series incorporates a built-in thermistor and TEC, contributing to its exceptional stability and performance. This careful engineering ensures that the laser diode maintains a consistent output power and wavelength, crucial for high-precision optical applications. Furthermore, the device's narrow line width and high side-mode suppression ratio (SMSR) guarantee superior signal clarity and reduced interference, making it an ideal choice for advanced optical systems.
