Low-speed DWDM industrial digital SFP optical module

Xinrui Technology's low-speed DWDM industrial digital SFP optical modules are suitable for industrial environments under extreme conditions, with ultra-wide low-speed communication capabilities such as DC~10Mbps and DC~20Mbps. They are compatible with industrial protocols like RS-485 and CAN, meeting the high-precision control requirements of PLCs, sensors, etc. Adopting SFP packaging and LC single-fiber interface, and equipped with DWDM technology, they can optionally use ITU-T standard wavelengths (such as 1550nm/1310nm), significantly saving fiber resources through single-fiber multi-channel multiplexing. The modules are equipped with DFB lasers and PIN detectors, supporting transmission distances of 20~80km, and are compatible with the SFF-8472 digital diagnostic interface, which can monitor optical power and temperature status in real-time to ensure zero transmission errors. At the hardware level, they adopt a 3.3V low-power design (≤1W), LVTTL logic level, and ≥8kV ESD protection to enhance anti-interference performance. Optional metal shell customization solutions (EMI suppression ≤30dB) are available. They have passed military-industrial grade (-45℃~85℃) or military extended grade (-55℃~85℃) wide temperature certification and IEC 60068 vibration test, and can withstand harsh conditions such as strong electromagnetic interference, high humidity, and mechanical shock, with an MTBF of over 200,000 hours. The product deeply supports protocol privatization and flexible wavelength configuration, and is widely used in scenarios such as smart factories, power relay protection, oil and gas monitoring, and rail transit. With high reliability and low latency, it promotes the integration of industrial OT/IT networks and helps with localized independent and controllable replacement.
