In today’s era of rapid development in industrial automation and smart manufacturing, real-time, stable data communication is the core of a factory’s nervous system. Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as “Mingjiada Electronics”), as a leading hybrid distributor of electronic components, leverages its robust global procurement network and strong stock inventory to consistently supply genuine, imported Broadcom QFBR-5978AZ-2 650 nm digital diagnostic transceivers. At the same time, we offer high-value buyback services for this model and various types of idle electronic inventory, helping businesses free up capital.
This device is specifically optimized for PROFINET industrial Ethernet applications and is an ideal choice for building high-speed links between plastic optical fiber (POF) and hard-clad silica (HCS) fiber. Whether you are engaged in equipment R&D, production line upgrades, or stocking for maintenance, Mingjiada Electronics offers highly competitive pricing and fast delivery services.
Product Technical Overview: Designed for Demanding Industrial Environments
The QFBR-5978AZ-2 is a high-performance fiber optic transceiver from Broadcom. Unlike standard communication modules, it features a Digital Monitoring Interface (DMI), allowing systems to monitor key internal parameters in real time, significantly enhancing the convenience of predictive maintenance and troubleshooting in industrial settings.
Key Specifications and Features
Brand and Model: Broadcom QFBR-5978AZ-2
Operating Wavelength: 650 nm (visible red light, facilitating maintenance and inspection)
Data Rate: 100 Mb/s (compatible with Fast Ethernet)
Connector Type: SC-RJ duplex interface
Fiber Type and Transmission Distance:
Plastic Optical Fiber (POF, 1mm): Up to 50 meters
Hard-clad silica fiber (HCS): Up to 100 meters
Graded-index HCS: Up to 250 meters
Operating Temperature: -40°C to +90°C (meets the demands of harsh industrial environments)
Diagnostic Functions: Supports real-time monitoring of received optical power, temperature, supply voltage, and OMA (optical modulation amplitude) margin
Electrical Interface: LVPECL Input/Output
Why Choose the QFBR-5978AZ-2?
Interference Resistance and Stability: In high electromagnetic interference environments such as those found near variable frequency drives and large motors, 650 nm optical fiber communication offers a significant advantage over copper cables in terms of interference resistance, ensuring zero data packet loss.
Compliance with PROFINET Standards: This device strictly adheres to the PROFINET standard’s performance requirements for POF/HCS fiber and is compatible with mainstream PLCs and industrial switches.
Intelligent Digital Diagnostics: Through the SFF-8472 standard digital monitoring interface, engineers can read the transceiver’s temperature and optical power in real time, providing early warnings of potential failures before the link is completely interrupted.
Application Scenarios
