High-performance 25G SFP28 transceivers, optimized for French regional telecom carriers and local cloud hosting clusters.
France is currently experiencing a historic leap in enterprise digitalization and high-speed telecom distribution. Backed by the national digital initiative "Plan France Très Haut Débit", telecommunications giants like Orange, SFR, Bouygues Telecom, and Free are rapidly upgrading infrastructure to handle the massive volumes of traffic generated by 5G networks, cloud computing, and IoT systems. To meet these rigorous throughput needs without escalating operational expenditures, 25G and 32G SFP28 modules have emerged as the standard structural upgrade paths.
SFP28 (Small Form-Factor Pluggable 28) represents the evolutionary interface offering 25Gb/s speed over a single lane, compatible with existing SFP+ structural spaces. For data centers in major metropolitan hubs like Paris (the FLAP datacenter zone), Marseille, and Lyon, this technology transition from 10G to 25G provides a 2.5x increase in bandwidth while utilizing minimal rack space and strictly conserving energy. Simultaneously, the 32G Fibre Channel SFP28 modules serve as the backbone for high-performance Storage Area Networks (SAN) in banking, automotive engineering, and critical government database applications across the French republic.
Operate at a native 25Gbps rate using a single electrical lane, drastically lowering complexity and hardware cost compared to QSFP options.
Engineered for lower power draw (< 1W typical), addressing stringent European Union data center green energy policies and operational directives.
Full support for 25G Ethernet, 32G Fibre Channel, eCPRI (for 5G radio networks), and backward compatibility with 10G SFP+ ports.
Deploying 25G Ethernet or 32G Fibre Channel inside complex modern environments requires an exact understanding of optical dispersion, attenuation parameters, and module interfaces. For short-reach requirements inside the same server rack or adjacent aisles, SFP28 SR (Short Reach) modules operating over OM3 or OM4 Multimode Fiber (MMF) at 850nm utilize VCSEL laser arrays to deliver ultra-low latency connection profiles up to 100 meters.
For span requirements crossing campus zones or metropolitan rings, single-mode fiber architectures dictate the use of SFP28 LR (Long Reach - 10km) and SFP28 ER (Extended Reach - 40km) transceivers. These incorporate cooled DFB (Distributed Feedback) or EML (Electro-absorption Modulated) lasers operating in the 1310nm window where silica fiber attenuation is low. In highly dense urban environments where physical fiber leases are prohibitively expensive, our SFP28 BiDi (Bidirectional) transceivers utilize WDM technology (e.g., pairing 1270nm and 1330nm wavelengths) to double transport capability over a single optical strand, drastically optimizing capital and operational budgets.

As an established industry pioneer founded in 2016, Novafiber Communications Co., Ltd. has spent nearly a decade refining the science of fiber optic communication. Operating from our advanced 420㎡ production facility, our focus is centered on high-efficiency execution, stable yields, and extensive device interoperability. With 9 years of engineering background and 7 years of active global export success, we deliver high-performance optical transceiver solutions to system integrators, data center operators, and telecommunications companies in France and across Europe.
Our strict quality assurance protocols are built around IPC standards, automated optical testing (AOT), and Environmental Stress Screening (ESS). To ensure absolute field reliability, every batch of 25G and 32G SFP28 modules undergoes 100% functional validation, hardware burn-in testing, and high-temperature aging cycles. Driven by our 180-engineer research department, Novafiber launched over 320 new product variations in the past year alone, demonstrating our leadership in dynamic optical firmware design and customized packaging solutions.

Real-time Bit Error Rate Testing
Rigorous Environmental Stress Screening
100% Interoperability Validation
One of the biggest concerns for telecom procurement in France is compatibility. Installing third-party transceivers into systems from Cisco, Arista, Juniper, or Nokia shouldn't lead to warning alerts or port disablements. At Novafiber, we compile and code custom EEPROM files containing exact vendor-compatible registers. This ensures our 25G/32G SFP28 modules plug in seamlessly, presenting proper diagnostics, temperatures, and signal levels via standard Digital Diagnostic Monitoring (DDM).
Engineered for long-haul networks, DWDM system integrations, and bi-directional single-fiber setups across Europe.
Procuring network components for French critical infrastructures requires strict adherence to European regulations. All Novafiber 25G/32G SFP28 modules are certified compliant with CE, RoHS, and WEEE directives. By designing with zero lead content and halogen-free substrates, our hardware aligns perfectly with the environmental sustainability policies that enterprise clients and government bodies mandate in France.
We maintain a optimized supply pipeline to ensure rapid delivery. Utilizing direct air cargo shipping lanes to Paris Charles de Gaulle (CDG) and Lyon-Saint Exupéry (LYS) airports, we streamline custom clearances and localized distribution. Most high-volume orders are prepared, programmed, fully tested, and dispatched within days, cutting lead times to a minimum so your operations can keep expanding on schedule.

Yes, many dual-rate modules (like the Cisco compatible SFP-10/25G-CSR-S) are designed to run at both 10G and 25G speeds. However, the host switch port must support speed configuration down to 10G. It is highly recommended to verify port capabilities before ordering.
Novafiber SFP28 modules are engineered to draw under 1 Watt of power per port, which is significantly lower than legacy multi-channel QSFP solutions. Reduced heat dissipation lowers the cooling load of the facility, directly helping operators meet strict PUE (Power Usage Effectiveness) targets required by EU environmental standards.
While sharing the exact physical design, they use different protocols and signal speeds. 25G SFP28 runs on Ethernet standard profiles (typically for IP networking), whereas 32G SFP28 operates at 28.05 Gbps, conforming to Fibre Channel (FC) standards for storage arrays (SAN) common in banking and server clusters.
Yes. Our R&D facility houses compatibility testing beds representing over 50 mainstream networking brands (Cisco, Juniper, Arista, Dell, HP, Nokia, etc.). We program the EEPROM/firmware on each module to ensure proper DDM telemetry reporting and absolute interoperability.
For standard stocked items, we ship within 2–3 business days. By partnering with leading international couriers, we facilitate customs clearance at CDG or Marseille. Delivery to major French destinations is usually accomplished within 5–7 working days.
