A company that makes optical communication tools started with hand tools like thermal strippers and has grown to produce precision testing instruments like OTDRs. Nanjing VAEYI Technology's product expansion path is worth analyzing.
Fiber optic splicing is a fundamental operation in fiber optic installation and maintenance. Before splicing, the coating layer must be removed, and the tool used for this step is a fiber optic stripper (hot stripper). Although it's a hand tool, it requires considerable skill—the stripping of the coating layer must not damage the fiber cladding, otherwise the splicing loss will be significant. The precision of the stripper's blade, the hardness of its material, and the spring return force all directly affect the stripping quality and the success rate of the splicing.
Nanjing VAEYI Technology entered this niche market and accumulated experience in designing and manufacturing optical communication installation and maintenance tools. The value of this experience lies in its deep understanding of the actual operating habits and pain points of installation and maintenance engineers, which laid a foundation of scenario-based knowledge for subsequent development of testing instruments.
Making tools and making instruments are two different things. Tools solve the problem of "operation" (how to peel, how to cut, how to melt), while instruments solve the problem of "judgment" (whether it is working, how much loss, where the break is).
However, both serve the same user group—optical communication installation and maintenance engineers. The engineer's complete work chain is: fiber stripping → splicing → testing → acceptance → maintenance. Nanjing VAEYI Technology starts with the tools at the beginning of the chain and naturally extends to the testing instruments at the end.
This extension logic isn't about blind expansion. After installation and maintenance engineers complete the fusion splicing, the next step is to test the connection. If the tool company only handles the stripping but not the testing, users will have to buy testing equipment from other manufacturers. Extending the product line along the work chain not only provides users with complete solutions but also increases user stickiness.
OTDR is a high-tech product among optical communication test instruments. The transition from thermal strippers to OTDR represents a leap not only in product form but also in technological dimension.
· Optical design: laser driver, photoelectric receiver, optical filter
· Signal processing: weak signal amplification, digital sampling, algorithm analysis
· Software development: curve display, automatic event recognition, data management
· Structural design: portability, heat dissipation, electromagnetic compatibility, shock resistance
The FA1000 integrates six major functions: OTDR, stable light source, optical power meter, red light source, network cable testing, and data storage. It features a 4.3-inch capacitive touchscreen, weighs 0.5kg, and has a 4000mAh battery. Achieving this level of integration and portability requires technological capabilities across multiple fields, including optics, electronics, software, and structural engineering.
By analyzing Nanjing VAEYI Technology's product line, a clear matrix structure can be observed:
Tools layer : Fiber optic strippers (hot strippers) and other fusion splicing auxiliary tools. Addressing the "how to operate" question.
Test layer : FA8000 (PON network line comprehensive tester) and FA1000 (multi-functional optical time domain reflectometer). Solving the problem of "how to judge".
The FA8000 is designed for dedicated PON network testing and requires penetration through optical splitters; the FA1000 is designed for general installation and maintenance testing, integrating six functions to cover various testing needs. The two products form a "private network + general purpose" testing combination.
The logic behind this product matrix is: the tool layer solves operational problems, the testing layer solves judgment problems, and the two layers together cover the complete workflow of installation and maintenance engineers.
The FA1000 is a "wide-coverage" model in Nanjing VAEYI Technology's testing product line. It is positioned as a general-purpose installation and maintenance comprehensive testing product, featuring six-in-one integration, dual-mode operation, portability, and long battery life.
In terms of specifications, the FA1000A has a dynamic range of 30dB (1310nm), an event blind zone of 3m, an attenuation blind zone of 8m, and a range of 300m-120km. These specifications are sufficient for installation and maintenance scenarios—the goal is not to achieve laboratory-level accuracy, but rather to prioritize field practicality and efficiency.
The FA1000 is further subdivided into two models: the FA1000A is a 1310/1550nm dual-wavelength standard test model, suitable for acceptance testing of new links; the FA1000F is a 1625nm single-wavelength online test model, suitable for uninterrupted maintenance of existing service lines. These two models correspond to the "construction phase" and the "operation phase," with one product series covering the entire lifecycle of the link.
The FA1000's dual design of automatic and expert modes reflects the hierarchical nature of its product matrix: automatic mode lowers the barrier to entry, allowing more engineers to use OTDRs; expert mode retains refined operational capabilities, meeting the needs of experienced engineers. VAEYI has always adhered to the design principle of "adapting to users with different skill levels" in its product planning.
The FA1000 integrates six functions—OTDR, stable light source, optical power meter, red light source, network cable testing, and data storage—a decision based on the breakdown of the installation and maintenance workflow.
From start to finish, installation and maintenance engineers only need these five testing functions (data storage is secondary). Single-function devices mean carrying multiple instruments, which means being heavy, disorganized, and slow. Nanjing VAEYI Technology chose to integrate all five functions into one device, adding only 0.5kg of weight and a 4000mAh battery, allowing engineers to use a single device for all tasks.
This is not a simple aggregation of functions. The modulation modes of the stable light source (CW/270Hz/1kHz/2kHz) and the frequency identification of the optical power meter (CW/270Hz/330Hz/1kHz/2kHz) are designed in tandem—the modulation signal filters out ambient light interference and improves the accuracy of loss measurement. The 1310/1550nm dual wavelengths of the OTDR and the 650nm visible light of the red light source cover the entire process from connectivity checks to fine loss analysis. The synergy between these functions was planned during the product design phase, not pieced together later.
The expansion of the product portfolio is essentially Nanjing VAEYI Technology's transformation from a "tool supplier" to an "installation and maintenance solutions provider".
Tool vendors sell single-point products—if you need fiber strippers, I sell fiber strippers; if you need OTDRs, I sell OTDRs. Solution providers sell complete capabilities—covering the entire chain of equipment and tools, from fiber stripping to testing to acceptance.
This transformation is driven by user demand. Installation and maintenance engineers don't want to deal with five different suppliers; ideally, one supplier could meet all their needs. Nanjing VAEYI Technology has expanded its product line along the installation and maintenance workflow, with each step responding to this demand.
From hot strippers to OTDRs, the leap may seem large, but the underlying logic remains the same: providing handy tools for optical communication installation and maintenance engineers. VAEYI's product portfolio is still expanding, but the direction is clear—to follow the installation and maintenance work chain and delve deeper into it.
