10G Fronthaul DWDM SFP+ 80km Industrial Transceiver: DWDM-10GFH-SFP-80I

Our EDGEOPTIC DWDM-10GFH-SFP-80I is a multi-vendor compatible 10G Fronthaul DWDM SFP+ dual-fiber optical module designed for mobile network infrastructure supporting CPRI and OBSAI protocol standards with dense wavelength division multiplexing capability over ultra-long distances in harsh environmental conditions. The DWDM-10GFH-SFP-80I module is available across 45 DWDM channels (ITU channels 17-61) in the C-band with 100GHz spacing according to the ITU-T G.694.1 wavelength grid. With data rates from 1.228 to 10.138 Gbps, this industrial-grade transceiver enables maximum-density wavelength multiplexed fronthaul connectivity between baseband units and remote radio heads in 4G LTE and 5G network deployments requiring both extended reach and extreme temperature operation.

Our 10G Fronthaul DWDM 80km Industrial SFP+ transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and APD (Avalanche Photodiode) for receiving. The EML transmitter provides the narrow spectral width required for DWDM applications with tight channel spacing, while the APD receiver enables extended transmission distances. The module ensures a 23 dB guaranteed optical link budget, which determines the maximum transmission distance. Over single-mode fiber, the transceiver can reach distances up to 80 kilometers when deployed with appropriate DWDM multiplexing equipment. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry, including insertion losses from DWDM mux/demux devices.

DWDM technology allows maximum-density wavelength multiplexing with 0.8nm (100GHz) channel spacing, enabling up to 45 independent 10G connections over existing two-fiber infrastructure in the C-band alone. This represents significantly higher channel density compared to CWDM solutions, making it ideal for scenarios where fiber availability is extremely limited and long-distance transmission is required. Each transceiver must be ordered with the specific ITU channel wavelength required for the deployment.

The industrial temperature rating of -45°C to +85°C makes this transceiver ideal for outdoor cabinet installations, remote radio head locations exposed to environmental extremes, and deployments in regions with significant temperature variations. All optical and electrical parameters are guaranteed across the full extended temperature range, ensuring consistent fronthaul link performance regardless of ambient conditions.

The DWDM-10GFH-SFP-80I supports comprehensive fronthaul protocol coverage including CPRI options 2 through 8, ranging from 1228.8 Mbps to 10.138 Gbps. Additionally, the module supports OBSAI RP3 configurations at 1.536 Gbps, 3.072 Gbps, and 6.144 Gbps rates. This multi-rate capability ensures compatibility with diverse radio access network architectures and equipment generations from major RAN vendors worldwide.

The DWDM-10GFH-SFP-80I compatible 10G Fronthaul DWDM Industrial module is a hot-pluggable SFP+ with duplex LC/UPC connectors as an optical interface. The electrical interface conforms to SFF-8431 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP+ host systems supporting multiple vendor equipment platforms. Our 10G Fronthaul DWDM 80km Industrial SFP+ transceiver can be encoded to be compatible and successfully operate in different baseband unit and remote radio head platforms across the telecommunications industry.

The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is available via MSA-compatible EEPROM interface and enables monitoring of transceiver operational parameters across dense wavelength-multiplexed deployments in challenging environments over maximum distances.

Standards compliance includes SFF-8431 for mechanical and electrical specifications, ITU-T G.694.1 for DWDM wavelength grid, along with Class 1 FDA and IEC60825-1 laser safety requirements. Our 10G Fronthaul DWDM 80km Industrial SFP+ transceiver is CE/RoHS certified and compliant with product safety standards.

Typical applications include ultra-high-density outdoor C-RAN fronthaul deployments over regional distances, fiber-scarce scenarios requiring maximum channel count with extended reach in extreme climates, and carrier-class mobile network infrastructure where absolute fiber capacity optimization across long distances with industrial-grade environmental resilience is critical. Because our focus is providing top quality service, we perform serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests, and SFP+ transceiver EEPROM memory data validation tests.
