25G Fronthaul SR SFP28 Industrial Transceiver: 25GFH-SFP28-100I

Our EDGEOPTIC 25GFH-SFP28-100I is a multi-vendor compatible 25G Fronthaul SR SFP28 dual-fiber optical module engineered for mobile fronthaul applications in demanding outdoor and industrial environments. Featuring an extended operating temperature range from -45°C to +85°C, this industrial-grade transceiver delivers reliable high-speed connectivity for 5G and LTE network deployments where equipment may be exposed to extreme environmental conditions.

The 25GFH-SFP28-100I 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 challenging fronthaul environments.

Our 25G Fronthaul SR SFP28 industrial 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, enabling transmission distances up to 100 meters over OM3/OM4/OM5 multimode fiber infrastructure. The transmitter operates within a wavelength bandwidth of 20nm 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-SFP28-100I 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 industrial-grade 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 capability becomes particularly valuable in industrial deployments where environmental monitoring is essential for proactive maintenance. Maximum power consumption of 1W supports the enhanced thermal management required for extended temperature operation.

The industrial temperature range of -45°C to +85°C makes this transceiver ideal for outdoor cabinet installations, cell tower equipment shelters, and remote radio unit deployments where temperature fluctuations are common. 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 outdoor 5G fronthaul connections, C-RAN (Centralized Radio Access Network) deployments in harsh environments, street-level small cell backhaul, and industrial mobile network infrastructure where standard commercial-grade modules cannot withstand temperature extremes.

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 mission-critical fronthaul network.
