25GBASE-LR SFP28 Industrial Transceiver: 25G-SFP28-10I

Our EDGEOPTIC 25G-SFP28-10I is a multi-vendor compatible industrial-grade 25GBASE-LR SFP28 dual-fiber optical module designed for 25 Gigabit Ethernet applications in harsh environmental conditions. The 25G-SFP28-10I module operates at 1310nm wavelength for both transmission and reception, with data rates from 8.5 to 28.1 Gbps supporting multiple protocol standards and applications. Our industrial 25GBASE-LR SFP28 transceiver utilizes DML (Directly Modulated Laser) technology for transmission and PIN photodiode for receiving, engineered specifically for reliable long-reach connectivity in extreme temperature environments.

The transceiver ensures an 8 dB guaranteed optical link budget with host-based Forward Error Correction (FEC) support, which determines the maximum transmission distance capabilities. Over standard single-mode fiber (SMF), the module achieves reliable transmission up to 10 kilometers, making it ideal for outdoor installations, industrial campus interconnects, and utility infrastructure deployments. However, distance is just an indicative parameter calculated for convenience of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry standards. The robust design maintains consistent optical performance across the entire industrial temperature range, ensuring stable connectivity in challenging deployment scenarios.

25G-SFP28-10I compatible industrial 25GBASE-LR module is hot-pluggable SFP28 with duplex LC/UPC connectors as an optical interface. The electrical interface conforms to SFF-8431 and SFF-8432 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP28 host systems supporting multiple vendor equipment platforms. Our industrial 25GBASE-LR SFP28 transceiver can be encoded to be compatible and successfully operate in different 80+ brands of equipment. The module incorporates comprehensive DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is available via MSA-compatible EEPROM interface per SFF-8472 specifications, enabling continuous monitoring of transceiver operational parameters across extreme temperature variations.

The module operates within an extended industrial temperature range of -45°C to +85°C, with maximum power consumption of 1.2W, specifically designed for deployment in uncontrolled environments including outdoor cabinets, remote cell sites, industrial facilities, and transportation infrastructure. The enhanced thermal design with industrial-grade components ensures stable DML laser operation and maintains the 3.5 dB minimum extinction ratio across the entire temperature spectrum. Standards compliance includes IEEE 802.3cc specifications for 25 Gigabit Ethernet, supporting both 10G Ethernet (10.31 Gbps) and 25G Ethernet (25.78 Gbps) applications. The transceiver achieves multi-vendor interoperability through adherence to SFP28 MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for compatibility.

Our industrial 25G SFP28 LR transceiver is CE/RoHS certified and compliant with Class 1 FDA and IEC60825-1 laser safety standards. Typical applications include industrial automation networks, smart grid communications, outdoor wireless backhaul systems, transportation infrastructure, mining operations, and oil and gas facilities. The multi-rate capability accommodates legacy 10 Gigabit Ethernet operation alongside native 25 Gigabit rates, providing operational flexibility for mixed-speed network deployments in harsh environments. Because our focus is providing top quality service, we perform extensive environmental testing including thermal cycling, vibration resistance, and humidity exposure tests, in addition to optical parameter measurements, connector cleanliness tests, and SFP28 transceiver EEPROM memory data validation tests.
