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

Our EDGEOPTIC CWDM-10GFH-SFP-80I 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 over ultra-long distances in harsh environmental conditions. The CWDM-10GFH-SFP-80I module is available across 8 CWDM channels spanning from 1470nm to 1610nm according to the ITU-T G.694.2 wavelength grid. With data rates from 1.228 to 10.138 Gbps, this industrial-grade transceiver enables high-density wavelength multiplexed fronthaul connectivity between baseband units and remote radio heads in 4G LTE and 5G network deployments requiring both maximum reach and extreme temperature operation.

Our 10G Fronthaul CWDM 80km Industrial SFP+ transceiver utilizes DFB (Distributed Feedback) laser technology for transmission and APD (Avalanche Photodiode) for receiving. This enhanced receiver sensitivity enables the module to ensure 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 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. For ultra-long-reach applications, the module operates within the low-loss wavelength window (1470-1610nm), enabling up to 8 independent 10G connections over existing two-fiber infrastructure at maximum distances. Each transceiver must be ordered with the specific CWDM 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 CWDM-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 CWDM-10GFH-SFP-80I compatible 10G Fronthaul CWDM 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 CWDM 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 wavelength-multiplexed deployments in challenging environments over maximum distances.

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 80km Industrial SFP+ transceiver is CE/RoHS certified and compliant with product safety standards.

Typical applications include high-density outdoor C-RAN fronthaul deployments over regional and rural distances, fiber-constrained scenarios requiring multiple wavelength channels with maximum reach in extreme climates, and carrier-class mobile network infrastructure where maximizing fiber capacity across ultra-long distances with industrial-grade environmental resilience 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.
