Deltavox
Deltavox Optics Technologies Co., Ltd. is a professional optical communication solutions provider specializing in the design, manufacturing, and global supply of high-performance optical transceivers. Established in 2016, the company operates from a modern manufacturing facility with a building area of 18,500㎡. With 12 years of industry experience and 7 years of specialized export heritage, we have solidified our reputation as a trusted authority in the photonics market.
Our commitment to "Information Gain" in the industry is reflected in our robust R&D pipeline. In the past year alone, Deltavox Optics successfully launched 168 new optical communication products. This innovation is fueled by a professional team of 126 optical engineers and technical specialists who focus on optimizing signal integrity, reducing power consumption, and enhancing thermal management in SFP28 modules.
The transition from 10G to 25G represented a fundamental shift in data center architecture. SFP28 (Small Form-factor Pluggable 28) has emerged as the preferred interface for 25Gbps Ethernet, providing a 2.5x increase in bandwidth without a proportional increase in power or cost. As we look toward the future, the roadmap for SFP28 is evolving into two distinct directions:
The 32G SFP28 module is the cornerstone of modern SAN (Storage Area Network) environments. Designed for the 6th generation of Fibre Channel (Gen 6), it offers backward compatibility with 16G and 8G FC, ensuring a seamless upgrade path for enterprises looking to eliminate storage bottlenecks in high-density virtualization environments.
With the global rollout of 5G, the demand for 25G SFP28 BiDi and CWDM/DWDM modules has surged. These modules support CPRI/eCPRI protocols, crucial for the connectivity between BBU (Baseband Unit) and RRU (Remote Radio Unit). Deltavox’s 25G industrial-grade transceivers are engineered to withstand extreme temperatures (-40°C to +85°C) required for outdoor 5G deployments.
While 25G currently relies primarily on NRZ (Non-Return-to-Zero) signaling for its simplicity and low latency, the next generation (50G SFP56) is transitioning to PAM4. Our R&D team is currently bridging these technologies to ensure that current SFP28 deployments can coexist within the next-tier architectures of 100G and 400G networks.
At Deltavox Optics, we leverage the "Factory 4.0" philosophy to provide our global clients with unparalleled supply chain stability. Our manufacturing process is not just about assembly; it’s about intelligent data-driven production.
Our facility utilizes high-precision automated bonding and laser welding machines. Every 25G SFP28 module undergoes rigorous automated optical testing, transmission performance verification, and temperature cycling. This reduces human error and ensures a defect rate far below industry averages.
By maintaining long-term partnerships with 850 strategic upstream suppliers, we secure priority access to high-end EML/DFB lasers and IC chipsets. This resilience allows us to maintain stable lead times even during global component shortages, providing a significant competitive advantage for our clients.
Understanding the "Search Intent" of enterprise buyers means recognizing that they aren't just looking for hardware—they are looking for a solution to a business problem. Deltavox Optics provides tailored solutions across several key sectors:
For hyperscale data centers, we offer 25G SFP28 SR and LR modules that are 100% compatible with major OEM switches (Cisco, Arista, Juniper, Mellanox). Our "Compatibility Lab" tests each module in original brand environments to guarantee plug-and-play reliability.
In the financial sector, every microsecond counts. Our ultra-low latency SFP28 transceivers are optimized for HFT networks, ensuring that data transmission is consistent and jitter is minimized under heavy load.
Navigating global trade requires strict compliance. Deltavox ensures all products meet CE, FCC, RoHS, and REACH standards. We provide localized technical support for North America, Europe, and Southeast Asia, ensuring that procurement teams have technical assistance in their time zone.
While they share the same physical form factor, SFP+ is designed for 10Gbps, whereas SFP28 is designed for 25Gbps. SFP28 uses upgraded electrical lanes and better clock recovery (CDR) to handle higher data rates with superior signal integrity.
Yes, many 25G SFP28 modules are "dual-rate" (10/25G) and can auto-negotiate down to 10Gbps if the host switch port supports it. This makes them an excellent choice for future-proofing your network cabling infrastructure.
We use a specialized EEPROM coding process. Each module is programmed with the specific vendor code and serial number required by the host system to pass the "authentic transceiver" check, followed by verification on actual Cisco/Arista hardware.
These modules allow for Wavelength Division Multiplexing, meaning you can send multiple 25G signals over a single pair of fibers (or even a single fiber). This is crucial for maximizing existing fiber plant capacity in metropolitan and 5G front-haul networks.
Thanks to our Factory 4.0 integrated supply chain, standard SFP28 SR/LR modules typically have a lead time of 3-5 business days, while customized CWDM/DWDM solutions range from 7-10 days.
