25GBASE-SR SFP28 Compatible Transceiver: 25G-SFP28-100

Our EDGEOPTIC 25G-SFP28-100 is a multi-vendor compatible 25GBASE-SR SFP28 dual-fiber optical module designed for 25 Gigabit Ethernet applications operating over multimode fiber cabling. The 25G-SFP28-100 module operates at 850nm wavelength for both transmission and reception, with data rates from 8.5 to 28.1 Gbps supporting multiple protocol standards and applications. Our 25GBASE-SR SFP28 transceiver utilizes VCSEL (Vertical-Cavity Surface-Emitting Laser) technology for transmission and PIN photodiode for receiving, providing optimal performance in short-reach multimode fiber deployments.

The transceiver ensures a 5.3 dB guaranteed optical link budget when operating with host-based Forward Error Correction (FEC), which determines the maximum transmission distance capabilities. Over OM3 multimode fiber, the module achieves 70 meters reach, while OM4/OM5 cabling extends transmission distance up to 100 meters. 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 FEC support enhances signal integrity and extends reach by correcting transmission errors, making this transceiver ideal for demanding data center environments.

25G-SFP28-100 compatible 25GBASE-SR 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 25GBASE-SR 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.

The module operates within a 0 to 70°C temperature range with exceptionally low power consumption of 0.3W maximum, making it ideal for high-density deployments in controlled server room environments. Standards compliance includes IEEE 802.3 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 25G SFP28 SR transceiver is CE/RoHS certified and compliant with Class 1 FDA and IEC60825-1 laser safety standards. Typical applications include data center leaf-spine architectures, high-performance computing clusters, enterprise campus networks, and cloud infrastructure deployments. The multi-rate capability accommodates legacy 10 Gigabit Ethernet operation alongside native 25 Gigabit rates, providing operational flexibility for mixed-speed network deployments. Because our focus is providing top quality service, we perform rigorous quality checks before delivery including optical parameter measurements, connector cleanliness tests, and SFP28 transceiver EEPROM memory data validation tests.
