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

Our EDGEOPTIC 25GFH-SFP28-20I is a multi-vendor compatible 25G Fronthaul LR SFP28 dual-fiber optical module engineered for extended-distance mobile fronthaul applications in demanding outdoor and industrial environments. Featuring an operating temperature range from -45°C to +85°C combined with 20-kilometer reach over single-mode fiber, this industrial-grade transceiver delivers reliable connectivity for geographically distributed 5G and LTE network deployments exposed to extreme environmental conditions.

The 25GFH-SFP28-20I 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 extended fronthaul distances in challenging thermal environments.

Our 25G Fronthaul LR SFP28 industrial 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, enabling reliable transmission over 20 kilometers of single-mode fiber regardless of ambient temperature fluctuations. 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 2 dBm.

The 25GFH-SFP28-20I 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 industrial-grade 25G Fronthaul LR 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 transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic capability becomes particularly valuable in outdoor industrial deployments where environmental monitoring is essential for proactive maintenance. Maximum power consumption is 1.2W.

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 across metropolitan areas. Standards compliance includes 25GBASE-LR and IEEE 802.3cc specifications. The module is CE marked and RoHS compliant.

Typical applications include outdoor metro-scale 5G fronthaul connections, extended C-RAN deployments in harsh environments, remote cell site connectivity, and industrial mobile network infrastructure requiring both extended reach and temperature resilience.

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.
