10G Fronthaul DWDM SFP+ 40km Transceiver: DWDM-10GFH-SFP-40

Our EDGEOPTIC DWDM-10GFH-SFP-40 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. The DWDM-10GFH-SFP-40 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 transceiver enables maximum-density wavelength multiplexed fronthaul connectivity between baseband units and remote radio heads in 4G LTE and 5G network deployments.

Our 10G Fronthaul DWDM 40km SFP+ transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and PIN photodiode for receiving. The EML transmitter provides the narrow spectral width required for DWDM applications with tight channel spacing. The module ensures a 14 dB guaranteed optical link budget, which determines the maximum transmission distance. Over single-mode fiber, the transceiver can reach distances up to 40 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. Each transceiver must be ordered with the specific ITU channel wavelength required for the deployment.

The DWDM-10GFH-SFP-40 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-40 compatible 10G Fronthaul DWDM 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 40km 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. The module operates within a 0 to 70°C temperature range, with appropriate thermal considerations for sustained operation in controlled equipment room environments.

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 40km SFP+ transceiver is CE/RoHS certified and compliant with product safety standards.

Typical applications include ultra-high-density C-RAN fronthaul deployments, fiber-scarce metropolitan scenarios requiring maximum channel count, and carrier-class mobile network infrastructure where absolute fiber capacity optimization 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.
