25G Fronthaul ER SFP28 40km Transceiver: 25GFH-SFP28-40

Our EDGEOPTIC 25GFH-SFP28-40 is a multi-vendor compatible 25G Fronthaul ER SFP28 dual-fiber optical module designed for long-distance mobile fronthaul applications in 5G and LTE network deployments. Operating over single-mode fiber infrastructure with reach up to 40 kilometers, this transceiver enables reliable high-speed connectivity for regional C-RAN architectures and extended metro-scale fronthaul networks where significant geographical distances must be bridged.

The 25GFH-SFP28-40 module operates at 1310nm wavelength for both transmission and reception, supporting data rates from 8.5 to 28.1 Gbps. This multi-rate capability enables compatibility with various CPRI (Common Public Radio Interface) options including CPRI Option 7 at 9.830 Gbps, Option 8 at 10.138 Gbps, Option 9 at 12.165 Gbps, and Option 10 at 24.33 Gbps. The transceiver explicitly supports eCPRI protocols alongside legacy CPRI standards and includes host-based Forward Error Correction for enhanced signal integrity across long-haul fronthaul distances.

Our 25G Fronthaul ER SFP28 transceiver utilizes DML (Directly Modulated Laser) technology for transmission and APD (Avalanche Photodiode) for signal reception. The APD receiver technology provides significantly enhanced sensitivity compared to PIN-based alternatives, which is essential for maintaining reliable links over extended distances. The module ensures a 16 dB guaranteed optical link budget, enabling transmission over 40 kilometers of single-mode fiber. The transmitter operates within a wavelength bandwidth of 30nm with launch power ranging from 0 dBm to 6 dBm. The receiver sensitivity spans from -19 dBm to -5 dBm with overload protection at -3 dBm.

The 25GFH-SFP28-40 compatible 25G Fronthaul ER module is a hot-pluggable SFP28 transceiver featuring duplex LC/UPC connectors as the optical interface. The electrical interface conforms to SFF-8431, SFF-8432, and SFP28 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP28 host systems across multiple vendor equipment platforms. Our 25G Fronthaul ER SFP28 transceiver can be programmed for compatibility with various network equipment manufacturers supporting fronthaul infrastructure.

The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time operational parameters including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is accessible via SFF-8472 compliant EEPROM interface, enabling continuous monitoring of transceiver health in mission-critical mobile network environments. Maximum power consumption is 1.5W.

The transceiver operates within a commercial temperature range of 0 to 70°C, suitable for controlled indoor installations. Standards compliance includes 25GBASE-ER, IEEE 802.3cc, and Class 1 FDA/IEC60825-1 laser safety certification. The module is CE marked and RoHS compliant.

Typical applications include regional 5G fronthaul connections, extended C-RAN architectures spanning metropolitan areas, long-distance inter-site fronthaul links, and mobile network infrastructure requiring maximum single-mode fiber reach.

Because our focus is providing top quality service, we perform comprehensive quality checks before delivery of our products. As a result, we conduct optical parameter measurements, connector cleanliness tests, and SFP28 transceiver EEPROM memory data validation tests to ensure reliable operation in your fronthaul network.
