25G Fronthaul DWDM SFP28 15km Transceiver: DWDM-25GFH-SFP28-15

Our EDGEOPTIC DWDM-25GFH-SFP28-15 is a multi-vendor compatible 25G Fronthaul DWDM SFP28 dual-fiber optical module designed for high-density wavelength-division multiplexed mobile fronthaul applications in 5G and LTE network deployments. Supporting 45 DWDM channels on the ITU-T C-Band 100 GHz grid (channels 17-61), this transceiver enables maximum fiber utilization for large-scale fronthaul aggregation requiring the highest channel density.

The DWDM-25GFH-SFP28-15 module transmits and receives on selectable DWDM wavelengths across ITU-T channels 17-61 with 100 GHz spacing in the C-Band. The transceiver supports data rates from 8.5 to 28.1 Gbps, enabling 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. Host-based Forward Error Correction support enhances signal integrity across dense wavelength-multiplexed fronthaul links.

Our 25G Fronthaul DWDM SFP28 transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and PIN photodiode for signal reception. The EML transmitter provides the precise wavelength control and narrow spectral width essential for reliable DWDM operation on the 100 GHz grid. The module ensures a 14 dB guaranteed optical link budget, enabling reliable transmission over 15 kilometers of single-mode fiber when deployed with appropriate DWDM multiplexing equipment. The transmitter operates within a tight wavelength bandwidth of 0.8nm (100 GHz) with launch power ranging from 0 dBm to 5 dBm. The receiver sensitivity ranges from -14 dBm to 2 dBm with overload protection at 2 dBm.

The DWDM-25GFH-SFP28-15 compatible 25G Fronthaul DWDM 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 25G Fronthaul DWDM SFP28 transceiver can be programmed for compatibility with various network equipment manufacturers supporting dense wavelength-multiplexed 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 multiplexed fronthaul environments. Maximum power consumption is 2W.

The transceiver operates within a commercial temperature range of 0 to 70°C, suitable for controlled indoor installations. Standards compliance includes 25GBASE-LR and IEEE 802.3 specifications. The module is CE marked and RoHS compliant.

Typical applications include high-density 5G fronthaul aggregation, large-scale C-RAN architectures requiring maximum wavelength channels over limited fiber infrastructure, DWDM-based metro fronthaul rings, and carrier-class mobile deployments where fiber scarcity demands the highest possible channel density per fiber pair.

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.
