In the rapidly evolving landscape of telecommunications and data networking, the 2.5G to 6G SFP (Small Form-factor Pluggable) module serves as a vital bridge between legacy hardware and the ultra-high-speed future. While 10G and 100G often dominate the headlines, the 2.5G~6G range remains the backbone for critical infrastructures including 5G fronthaul (CPRI/eCPRI), high-speed broadband access (GPON/XG-PON), and enterprise wireless backhaul (Wi-Fi 6/7).
Deltavox Optics Technologies Co., Ltd. stands at the forefront of this niche, providing specialized optical transceivers that balance power efficiency, thermal stability, and cost-effectiveness. Our 2.5G to 6G SFP series is engineered to support a wide range of protocols, from OBSAI and CPRI to standard Ethernet, ensuring seamless integration for global telecom operators and industrial networks.
As 5G NR (New Radio) deployments expand, the demand for 6.144 Gbps (CPRI Option 6) modules has surged. Our roadmap includes transitioning towards more robust eCPRI support, reducing latency for URLLC (Ultra-Reliable Low-Latency Communications) applications.
Future 2.5G~6G modules are moving toward Industrial Temperature (-40°C to +85°C) as standard, necessitated by outdoor 5G small cell deployments. Deltavox is pioneering advanced heat-sink designs to maintain signal integrity in harsh environments.
Fiber scarcity is a global challenge. Our R&D focus is on Bi-Directional (Bidi) and CWDM/DWDM technologies within the 2.5G~6G spectrum to double capacity over existing fiber infrastructure without additional cabling costs.
Our manufacturing philosophy is rooted in the Industry 4.0 paradigm. By integrating automation with deep domain expertise, Deltavox Optics ensures that every 2.5G SFP module leaving our facility is a masterpiece of precision engineering.
Automated optical testing ensures 100% consistency in TX power and RX sensitivity across high-volume batches.
A rigorous quality control team of 56 inspectors monitors every stage, from SMT to final packaging.
With 18,500㎡ of space, we handle massive OEM orders with lead times that outperform global competitors.
Our 850 partners ensure we have priority access to high-quality laser diodes (DFB/EML) and TOSA/ROSA components.
Supporting CPRI/OBSAI protocols for wireless base station connectivity. Our 6G SFP modules are optimized for the link between BBU (Baseband Unit) and RRU (Remote Radio Unit).
Enabling 2.5G Ethernet (2.5GBASE-T / 2.5GBASE-X) for modern Wi-Fi 6 access points, ensuring no bottleneck between the wireless air interface and the wired backbone.
High-resolution 4K/8K surveillance networks utilize 2.5G and 5G optical links to transport massive data streams from edge cameras to centralized storage hubs.
For global enterprises, "Reliability" means more than just a working module; it means compliance and local peace of mind. Deltavox Optics adheres to MSA (Multi-Source Agreement) standards, ensuring 100% compatibility with major brands like Cisco, Juniper, Arista, and Huawei.
When procuring 2.5G~6G SFP modules, technical buyers must look beyond the price per unit. "Information Gain" in procurement involves evaluating the Total Cost of Ownership (TCO).
Our lab stocks over 100 different brand switches to test host-module interoperability before shipping.
MTBF (Mean Time Between Failures) data is provided upon request, supported by our aging test protocols.
Custom labeling, unique casing designs, and specialized wavelength configurations for proprietary systems.
Green manufacturing processes that reduce energy consumption in both production and module operation.
Most modern 10G SFP+ ports are "multi-rate" and can auto-negotiate down to 2.5G or 1G. However, it depends on the switch's firmware. Deltavox provides specialized firmware to ensure our 2.5G modules are recognized correctly in 10G slots.
Commercial (C-temp) ranges from 0°C to 70°C, suitable for climate-controlled data centers. Industrial (I-temp) ranges from -40°C to +85°C, designed for outdoor cabinets and non-ventilated environments. We offer both for the entire 2.5G~6G range.
By combining 12 years of industry-specific engineering with a massive 18,500㎡ facility and a transparent supply chain of 850 partners, we demonstrate Expertise, Authoritativeness, and Trustworthiness in every transaction.
Yes, we specialize in 6G Bidi modules for CPRI applications, allowing transmission and reception over a single strand of fiber, which significantly reduces infrastructure costs for mobile operators.
