25G Fronthaul SFP28 20km Transceiver: 25GFH-SFP28-20

Our EDGEOPTIC 25GFH-SFP28-20 is a multi-vendor compatible 25G Fronthaul LR SFP28 dual-fiber optical module designed for extended-distance mobile fronthaul applications in 5G and LTE network deployments. Operating over single-mode fiber infrastructure with reach up to 20 kilometers, this transceiver enables reliable high-speed connectivity for geographically distributed C-RAN architectures and metro-scale fronthaul networks.

The 25GFH-SFP28-20 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 supports host-based Forward Error Correction for enhanced signal integrity across longer fronthaul distances.

Our 25G Fronthaul LR SFP28 extended-reach transceiver utilizes DML (Directly Modulated Laser) technology for transmission and PIN photodiode for signal reception. The module ensures a 10.5 dB guaranteed optical link budget, providing additional margin compared to standard 10km variants, which enables reliable transmission over 20 kilometers of single-mode fiber. The transmitter operates within a wavelength bandwidth of 40nm with launch power ranging from -5 dBm to 2 dBm. The receiver sensitivity spans from -13 dBm to 2 dBm with overload protection at 3 dBm.

The 25GFH-SFP28-20 compatible 25G Fronthaul LR 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 LR SFP28 extended-reach 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 1.2W.

The transceiver operates within a commercial temperature range of 0 to 70°C, suitable for controlled indoor installations typical of central office environments. Standards compliance includes 25GBASE-LR and IEEE 802.3cc specifications. The module is CE marked and RoHS compliant, meeting environmental and regulatory requirements.

Typical applications include metro-scale 5G fronthaul connections, extended C-RAN (Centralized Radio Access Network) architectures, inter-site fronthaul links across urban deployments, and mobile network infrastructure requiring longer single-mode fiber spans where standard 10km reach proves insufficient.

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.
