In the manufacturing process of fiber lasers, fiber optic sensors, and optical communication systems, there is a type of equipment that, while not as eye-catching as laser chips or optical lenses, directly determines the product's performance yield and production efficiency—these are fiber optic processing tools. From fiber cleaving and end-face preparation to fusion splicing and testing, every step requires the support of precision tools. Without high-quality cleavers and fusion splicers, even the most advanced fiber optic designs are difficult to translate into reliable end products.
Nanjing VAEYI Technology is a company that focuses on this field. Its products cover optical communication equipment such as fiber optic fusion splicers, fiber optic cleavers, and OTDRs, serving multiple niche markets such as fiber laser manufacturing, fiber optic sensor manufacturing, and university research laboratories.
Based on the known product information, VAEYI's product strategy is not simply about launching a single product category, but rather unfolds along the fiber optic processing flow:
Fiber optic fusion splicers : Representative models include the FA-36 four-motor fusion splicer and the FA-16, targeting fiber optic splicing and optical device manufacturing scenarios. The four-motor alignment structure has a technical advantage in core/cladding alignment accuracy and is suitable for applications with strict requirements on splice loss.
Fiber optic cleavers : including models such as the P12+ for conventional communication fibers, and the FCM-400+ for large-core fibers. These two product lines cater to different needs in fiber optic cable construction and maintenance, and industrial manufacturing/scientific research, respectively.
OTDR : Used for fiber optic link testing and fault location, it completes the toolchain from endface preparation to fusion splicing to link verification.
This approach of aligning with the entire process chain allows brands to provide users with complete tool solutions, from fiber preprocessing to final testing, rather than selling isolated individual products. For manufacturing companies, consistency in operational logic and after-sales service across tools from the same brand are also crucial considerations in actual procurement.
In VAEYI's product portfolio, the FCM-400+ large-core fiber optic cleaver is a landmark product—it is the brand's first tool designed for cutting and end-face fabrication of large-core fibers. The launch of this product signifies that the brand's service scope has officially expanded from the traditional field of fiber optic cable installation to high-end optoelectronic manufacturing fields such as fiber lasers and sensor manufacturing.
The core technical parameters of the FCM-400+ reflect its targeted design for large core diameter cutting needs:
FCM-400+ Key Parameters | |
Cladding diameter | 80–600μm |
Coating diameter | 160–3000μm |
Applicable optical fiber | Quartz optical fiber, active optical fiber, microstructure optical fiber, quartz tube |
Cutting angle | Average 0.2° (125μm) / 0.3° (250μm) / 0.4° (400μm) |
Blade life | Approximately 200,000 times (20 positions × 10,000 times/position) |
Cutting mode | Five settings: 200/300/400/500/600μm |
Power supply/size | Lithium battery / 160×100×113mm / 1.95kg |
The cladding diameter range of 80–600 μm covers the double-clad active fibers commonly used in current fiber lasers (such as ytterbium-doped fibers, where the inner cladding diameter is typically in the range of 250–400 μm), as well as the microstructured fibers used in fiber optic sensors. Five cutting modes, combined with an intelligent cutting program, automatically optimize the number of cuts. ZrO₂ ceramic fiber clamps ensure long-term clamping accuracy, and lithium battery power meets the mobile usage needs of production lines and laboratories.
These designs all point to one goal: to provide a stable, efficient, and low-maintenance-cost tool solution for fabricating large-core fiber endfaces.
The requirements for end-face processing tools in fiber laser and fiber sensor manufacturing differ significantly from those in traditional fiber optic cable installation. Understanding these differences is a prerequisite for developing suitable products.
fiber laser manufacturing , the quality of the cleaved end face of the active fiber directly affects the pump light coupling efficiency. An excessively large end face angle or defects can lead to increased coupling loss, decreased laser output power, and even an increased threshold. Furthermore, large-core active fibers are expensive, and the cost of wasted fiber due to poor cleaving is far higher than that of ordinary communication fibers. Therefore, the stability and yield of the cleaving tool are crucial.
fiber optic sensor manufacturing , the air pore structure inside microstructured optical fibers is prone to collapse or deformation during cutting, placing higher demands on blade sharpness, cutting stress control, and fixture protection. The FCM-400+'s explicit support for microstructured optical fibers, along with the low-damage characteristics of the smooth surface of the ceramic fixture, is a response to these needs.
Scientific research lab settings require equipment with wide compatibility and ease of operation. University and research institute projects frequently change fiber types and specifications; an 80–600μm coverage range and five adjustable modes eliminate the need for researchers to configure separate cutting equipment for each type of fiber. The unit's 1.95kg weight and lithium battery power also facilitate movement between different experimental setups.
In the industrial tool sector, after-sales service capabilities are a crucial consideration for users when choosing a brand. VAEYI offers a lifetime warranty on the FCM-400+, a service policy that is highly recognizable in the fiber optic dicing tool category. A lifetime warranty not only means that users will not incur repair costs throughout the entire lifespan of the equipment, but also conveys the brand's confidence in product reliability and long-term spare parts supply capabilities.
For fiber laser and sensor manufacturers, unexpected downtime of production equipment can delay the delivery of entire batches of products. A lifetime warranty, combined with the brand's R&D and service network in Nanjing, enables users to receive faster after-sales support and reduces the impact of equipment failures on production schedules.
Nanjing VAEYI Technology Co., Ltd. has gradually improved its product line from fusion splicers and cleavers to OTDRs, and entered the large-core fiber manufacturing track with the FCM-400+. It follows a pragmatic path of "focusing on the process chain, targeting specific needs, and building trust with quality and service".
The core of this approach lies in: not pursuing a large and comprehensive product category expansion, but rather delving deep into the professional field of fiber optic processing, understanding the specific needs of each type of fiber and each process, and winning users with targeted product design and reliable service commitments.
