Gigac Technology's DT-1414 optical transmitter module is a domestically produced alternative to Avago's HFBT-1414. It offers full Avago compatibility and comparable anti-interference capabilities to the HFBR-1414. It works with 850nm fiber and is suitable for low-power, low-cost optical interconnect solutions.
The DT-1414 is a transmitter packaged from an LED chip with a peak wavelength of 850nm. Utilizing advanced packaging technology, it offers excellent heat dissipation. Through the design of a heat dissipation channel and the use of highly thermally conductive materials, it effectively dissipates heat generated by the LED chip during operation, reducing its operating temperature and extending its lifespan and performance stability, ensuring stable module operation under long-term, high-load conditions. While maintaining performance, it achieves a compact and highly integrated package. This compact design makes the DT-1414 ideal for space-constrained applications such as small communications equipment and portable data transmission terminals, supporting device miniaturization and lightweighting while also helping to reduce overall system costs. The DT-1414's carefully designed package structure ensures excellent optical coupling between the LED chip and the optical fiber, maximizing optical signal transmission efficiency and minimizing optical energy loss. This efficient optical coupling not only improves module performance but also reduces drive current requirements, further reducing system power consumption.
The DT-1414 also boasts excellent transmission speed performance, meeting the demands of a wide range of high-speed data transmission applications. It achieves data transmission efficiency comparable to or even superior to that of the Avago HFBT-1414, ensuring fast and stable data transmission. It is suitable for applications such as communications and industrial control, where high-speed data transmission is crucial. The module offers stable optical output power, maintaining consistent power output under varying operating conditions. This ensures optical signal strength and transmission distance, effectively minimizing the impact of signal attenuation on transmission quality, and improving system reliability and stability. The emitted light wavelength is highly accurate, closely matching that of the Avago HFBT-1414 and exhibiting excellent stability. Precise wavelength control helps reduce the dispersion effect in optical fiber transmission, improve the quality and accuracy of signal transmission, and ensure that the signal can still maintain good integrity and recognizability after long-distance transmission.
