25G Fronthaul BiDi SFP28 30km Transceiver A-Side: BIDI-25GFH-SFP28-40A

Our EDGEOPTIC BIDI-25GFH-SFP28-40A is a multi-vendor compatible 25G Fronthaul BiDi SFP28 single-fiber optical module designed for long-distance fiber-efficient mobile fronthaul applications in 5G and LTE network deployments. Utilizing bidirectional technology over a single strand of single-mode fiber with reach up to 30 kilometers, this transceiver effectively doubles fiber capacity while enabling connectivity across regional fronthaul networks requiring extended reach.

The BIDI-25GFH-SFP28-40A 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 long-haul fronthaul distances. This A-Side module must be paired with a complementary B-Side transceiver (BIDI-25GFH-SFP28-40B) operating at opposite wavelengths to establish a complete bidirectional link.

Our 25G Fronthaul BiDi SFP28 long-reach transceiver utilizes DML (Directly Modulated Laser) technology for transmission and APD (Avalanche Photodiode) for signal reception. The APD receiver technology provides significantly enhanced sensitivity compared to PIN-based alternatives, which is essential for maintaining reliable single-fiber links over extended distances. The module ensures an 18 dB guaranteed optical link budget, enabling transmission over 30 kilometers of single-mode fiber. The transmitter operates within a wavelength bandwidth of 20nm with launch power ranging from 0 dBm to 6 dBm. The receiver sensitivity spans from -19 dBm to -5 dBm with overload protection at -5 dBm.

The BIDI-25GFH-SFP28-40A 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 25G Fronthaul BiDi SFP28 long-reach 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. 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 Class 1 FDA and IEC60825-1 laser safety certification. The module is CE marked and RoHS compliant.

Typical applications include fiber-constrained regional 5G fronthaul connections, extended C-RAN architectures spanning metropolitan and suburban areas where fiber availability is limited, single-fiber long-distance inter-site fronthaul links, and network infrastructure where maximizing existing fiber assets over significant distances is essential.

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.
