25G Fronthaul BiDi SFP28 20km Industrial A-Side: BIDI-25GFH-SFP28-20AI

Our EDGEOPTIC BIDI-25GFH-SFP28-20AI is a multi-vendor compatible 25G Fronthaul BiDi SFP28 single-fiber optical module engineered for extended-reach fiber-efficient mobile fronthaul applications in demanding outdoor and industrial environments. Combining bidirectional single-fiber technology with an operating temperature range from -45°C to +85°C and 20-kilometer reach, this industrial-grade transceiver maximizes fiber utilization while enabling connectivity across larger metropolitan fronthaul networks in harsh deployment conditions.

The BIDI-25GFH-SFP28-20AI module transmits at 1270nm wavelength and receives at 1330nm wavelength, 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 and includes host-based Forward Error Correction for enhanced signal integrity across extended fronthaul distances in extreme thermal conditions. This A-Side module must be paired with a complementary B-Side transceiver (BIDI-25GFH-SFP28-20BI) operating at opposite wavelengths to establish a complete bidirectional link.

Our 25G Fronthaul BiDi 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 20nm with launch power ranging from -4 dBm to 4 dBm. The receiver sensitivity spans from -11 dBm to 2 dBm with overload protection at 2 dBm.

The BIDI-25GFH-SFP28-20AI compatible 25G Fronthaul BiDi 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 industrial-grade 25G Fronthaul BiDi 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 where both fiber scarcity and temperature extremes present challenges. Standards compliance includes 25GBASE-LR along with Class 1 FDA and IEC60825-1 laser safety certification. The module is CE marked and RoHS compliant.

Typical applications include fiber-constrained outdoor metro-scale 5G fronthaul connections, extended C-RAN deployments in harsh environments with limited fiber availability, single-fiber remote cell site connectivity across urban areas, and industrial mobile network infrastructure requiring extended reach with fiber efficiency 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.
