GIGAC Technology's 0~50Mbps low-speed industrial control Duplex LC fiber SFP optical module features high reliability and deep adaptation to industrial scenarios as its core advantages. It adopts a dual-fiber bidirectional architecture, with physically isolated transmitting and receiving channels, significantly reducing the risk of co-frequency interference, and is particularly suitable for industrial sites with complex electromagnetic environments and strict requirements for signal stability. The module supports 0~20Mbps rate adaptation and is compatible with mainstream industrial protocols such as Modbus and Profinet, ensuring seamless connection with PLC and SCADA systems. With an industrial-grade wide temperature range (-40℃~85℃) and IP40 protection design, combined with anti-vibration and anti-shock structures, it can easily cope with harsh working conditions such as high temperature, high humidity, and mechanical vibration. Equipped with a low-power optoelectronic engine, the typical power consumption is ≤0.8W, and it is matched with a metal shell for efficient heat dissipation, extending the service life of the equipment. The entire link is domestically produced, has passed IEC 61373 vibration and shock tests and EMC Class 4 certification, with a mean time between failures of more than 200,000 hours. It is widely used in scenarios such as smart factory equipment networking, rail transit signal control, and power distribution network automation, providing a "zero bit error, maintenance-free" dual-fiber solution for industrial communications.
