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

Our EDGEOPTIC DWDM-25GFH-SFP28-15I is a multi-vendor compatible 25G Fronthaul DWDM SFP28 dual-fiber optical module engineered for high-density wavelength-division multiplexed mobile fronthaul applications in demanding outdoor and industrial environments. Combining 45 DWDM channel support on the ITU-T C-Band 100 GHz grid with an extended operating temperature from -45°C to +85°C, this industrial-grade transceiver enables maximum fiber utilization for large-scale fronthaul aggregation in harsh deployment conditions.

The DWDM-25GFH-SFP28-15I 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 in extreme thermal environments.

Our 25G Fronthaul DWDM SFP28 industrial transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and PIN photodiode for signal reception. The EML transmitter provides the precise wavelength control, narrow spectral width, and thermal stability essential for reliable DWDM operation across extended temperature ranges. 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-SFP28-15I 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 industrial-grade 25G Fronthaul DWDM 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 2W.

The industrial temperature range of -45°C to +85°C makes this transceiver ideal for outdoor cabinet installations, cell tower aggregation points, and remote equipment shelters where high-density wavelength multiplexing is required in extreme climates. Standards compliance includes 25GBASE-LR and IEEE 802.3 specifications. The module is CE marked and RoHS compliant.

Typical applications include outdoor high-density 5G fronthaul aggregation, large-scale C-RAN deployments in harsh environments, industrial DWDM-based metro fronthaul rings, and carrier-class mobile infrastructure where fiber scarcity and temperature extremes demand robust maximum-density wavelength multiplexing.

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.
