25G Fronthaul SR SFP28 Compatible Transceiver: 25GFH-SFP28-100

Our EDGEOPTIC 25GFH-SFP28-100 is a multi-vendor compatible 25G Fronthaul SR SFP28 dual-fiber optical module designed specifically for mobile fronthaul applications in 5G and LTE network deployments. This 25G Fronthaul SR transceiver operates over multimode fiber infrastructure, providing reliable high-speed connectivity between baseband units and remote radio heads in distributed antenna systems.

The 25GFH-SFP28-100 module operates at 850nm 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 in demanding fronthaul environments.

Our 25G Fronthaul SR SFP28 transceiver utilizes VCSEL (Vertical-Cavity Surface-Emitting Laser) technology for transmission and PIN photodiode for signal reception. The module ensures a 2.6 dB guaranteed optical link budget, which determines maximum transmission distance capabilities. Over OM3/OM4/OM5 multimode fiber, the transceiver achieves distances up to 100 meters. The transmitter operates within a wavelength bandwidth of 20nm (840-860nm) with launch power ranging from -5 dBm to 2.4 dBm. The receiver sensitivity spans from -10.3 dBm to 2.4 dBm with overload protection at 2.4 dBm.

The 25GFH-SFP28-100 compatible 25G Fronthaul SR 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 SR 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. With maximum power consumption of only 0.3W, the module offers excellent energy efficiency for high-density deployments.

The transceiver operates within a commercial temperature range of 0 to 70°C, suitable for controlled indoor installations typical of central office and data center environments. Standards compliance includes 25GBASE-SR specifications along with Class 1 FDA and IEC60825-1 laser safety certification. The module is CE marked and RoHS compliant, meeting environmental and regulatory requirements.

Typical applications include 5G and LTE fronthaul connections, C-RAN (Centralized Radio Access Network) architectures, distributed antenna systems, and mobile network infrastructure deployments. The multi-rate CPRI support accommodates various radio equipment configurations while maintaining signal integrity across the optical link.

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.
