10G Fronthaul CWDM SFP+ 20km Transceiver: CWDM-10GFH-SFP-10

Our EDGEOPTIC CWDM-10GFH-SFP-10 is a multi-vendor compatible 10G Fronthaul CWDM SFP+ dual-fiber optical module designed for mobile network infrastructure supporting CPRI and OBSAI protocol standards with wavelength division multiplexing capability. The CWDM-10GFH-SFP-10 module is available across 18 CWDM channels spanning from 1270nm to 1610nm according to the ITU-T G.694.2 wavelength grid. With data rates from 1.228 to 10.138 Gbps, this transceiver enables high-density wavelength multiplexed fronthaul connectivity between baseband units and remote radio heads in 4G LTE and 5G network deployments.

Our 10G Fronthaul CWDM SFP+ transceiver utilizes DFB (Distributed Feedback) laser technology for transmission and PIN photodiode for receiving. The module ensures a 9 dB guaranteed optical link budget, which determines the maximum transmission distance. Over single-mode fiber, the transceiver can reach distances up to 10 kilometers when deployed with appropriate CWDM 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 CWDM mux/demux devices.

CWDM technology allows multiple 10G fronthaul channels to share a single fiber pair by assigning each link a different wavelength with 20nm channel spacing. This approach dramatically increases fiber utilization in fronthaul networks, enabling up to 18 independent 10G connections over existing two-fiber infrastructure. Each transceiver must be ordered with the specific CWDM wavelength required for the deployment.

The CWDM-10GFH-SFP-10 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 CWDM-10GFH-SFP-10 compatible 10G Fronthaul CWDM 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 CWDM 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 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.694.2 for CWDM wavelength grid, along with Class 1 FDA and IEC60825-1 laser safety requirements. Our 10G Fronthaul CWDM SFP+ transceiver is CE/RoHS certified and compliant with product safety standards.

Typical applications include high-density C-RAN fronthaul deployments, fiber-constrained scenarios requiring multiple wavelength channels, and carrier-class mobile network infrastructure where maximizing fiber capacity is essential. 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.
