Detailed Product Description

Product Overview

The GIGAC DT-1414 Series is a domestically produced optical transmitter module designed as a full-compatibility alternative to the Avago (now Broadcom) HFBR-1414TZ. It offers equivalent anti-interference performance and optical output characteristics, operating at 820nm over hard-clad silica (HCS) and plastic optical fiber (POF) — the fiber types used in industrial fieldbus, motor drive isolation, and power electronics control systems.

The module is a transmitter-only device packaged from an 820nm LED chip with a peak wavelength closely matching that of the Avago HFBR-1414, providing excellent wavelength stability. Through advanced packaging technology including a dedicated heat dissipation channel and highly thermally conductive materials, the module effectively manages heat generated by the LED during operation, reducing operating temperature, extending lifespan, and ensuring performance stability under long-term, high-load conditions.

The DT-1414 achieves data transmission efficiency comparable to the Avago HFBR-1414, maintaining stable optical output power under varying operating conditions. Its carefully designed package structure ensures excellent optical coupling between the LED chip and optical fiber, maximizing signal transmission efficiency, minimizing optical energy loss, and reducing drive current requirements — further lowering system power consumption.

Technical Advantages

40 kV/μs Common-Mode Rejection — Built for High-Voltage Industrial Environments

A common-mode rejection ratio of 40 kV/μs is the defining performance parameter for optical transmitters used in power electronics applications. In motor drive inverters, IGBT gate driver circuits, and high-current converters, rapid voltage transitions on the power bus create common-mode noise that can corrupt control signals transmitted by optical modules with insufficient rejection. The 40 kV/μs rating of the DT-1414 series matches the HFBR-1414TZ specification, ensuring reliable signal transmission in 1200V IGBT drives and similar high-voltage platforms.

820nm HCS/POF Compatibility — Industrial Fieldbus Fiber Standard

HCS (Hard-Clad Silica) and POF (Plastic Optical Fiber) are the fiber types used in industrial fieldbuses including PROFIBUS, SERCOS, and proprietary motor drive optical links. Unlike standard telecom fiber (SMF/MMF), HCS and POF are designed for rugged industrial environments with larger numerical apertures for easier connector alignment and tolerance to mechanical bending. The 820nm wavelength matches the standard emission peak for HCS/POF LED transmitters used across the industrial automation ecosystem.

Thermal-Optimized Package — Long-Term Stability Under Load

The dedicated heat dissipation channel and high-conductivity thermal materials in the DT-1414 package address a common failure mode of LED optical transmitters in high-ambient environments: thermal drift of the LED's peak wavelength and output power over time. By effectively reducing the LED operating temperature, the thermal design extends module lifespan and maintains stable optical output in continuous-duty industrial installations where ambient temperatures can reach +60°C to +70°C.

Series Coverage — 10 Avago/Broadcom Cross-References

The GIGAC DT-1414 family covers 10 distinct Avago/Broadcom part numbers including both transmitter-only and receiver modules in the HCS/POF 820nm series. This allows procurement and engineering teams to consolidate multi-part Avago BOM items under a single qualified supplier, simplifying vendor approval and reducing supply chain complexity in equipment redesigns.
