25G Fronthaul SFP28 40km RX-Only Transceiver: 25GFH-SFP28-40RX

Our EDGEOPTIC 25GFH-SFP28-40RX is a multi-vendor compatible 25G Fronthaul SFP28 receive-only optical module designed for specialized long-distance mobile fronthaul applications requiring unidirectional signal reception. This single-fiber transceiver provides dedicated high-sensitivity receiver functionality for monitoring, testing, and asymmetric network architectures in 5G and LTE deployments spanning extended distances up to 40 kilometers.

The 25GFH-SFP28-40RX module receives at 1310nm wavelength with no transmitter function, 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. The receive-only design makes this transceiver ideal for long-distance signal monitoring applications, optical tap configurations in extended networks, and test equipment where only incoming signal detection is required.

Our 25G Fronthaul RX-Only SFP28 transceiver utilizes APD (Avalanche Photodiode) technology for signal reception, providing significantly enhanced sensitivity compared to PIN-based alternatives. This high-sensitivity receiver enables reliable detection across 40-kilometer single-mode fiber links typical of extended fronthaul deployments. The receiver operates within a wavelength bandwidth of 30nm with sensitivity ranging from -19 dBm to -5 dBm and overload protection at -3 dBm. This exceptional sensitivity range ensures reliable signal detection even after significant fiber attenuation over long distances.

The 25GFH-SFP28-40RX compatible 25G Fronthaul RX-Only module is a hot-pluggable SFP28 transceiver featuring a single LC/UPC connector 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 RX-Only SFP28 transceiver can be programmed for compatibility with various network equipment manufacturers.

The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time operational parameters including received optical power levels, module temperature, and supply voltage. This diagnostic data is accessible via SFF-8472 compliant EEPROM interface, enabling continuous monitoring of receiver performance in long-distance fronthaul monitoring applications. 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 long-distance fronthaul signal monitoring and analysis, optical splitter tap configurations for extended network visibility, test and measurement equipment integration for regional deployments, asymmetric fronthaul architectures spanning metropolitan areas, and network troubleshooting scenarios requiring high-sensitivity receive capability without transmit functionality.

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.
