Fujikura 28S Splicing Machines 28s Optical Fiber Splicer

Fujikura is a global leader in optical fiber fusion splicing, renowned for its high precision, reliability, and exceptional splicing quality. The 28S series represents its classic mid-to-high-end flagship product line, embodying state-of-the-art splicing technology at the time of its release. Although it has now been succeeded by the newer 90S series, the 28S remains widely used around the world due to its rugged durability and stable performance. It remains a popular choice on the secondary market and among many engineering companies.

Designed to meet the demanding requirements of fiber optic network deployment and maintenance, this series is suitable for various applications including FTTH (Fiber to the Home), core networks, and metropolitan area networks.

Key Features and Advantages

Excellent Splicing Quality & Low Loss

Core Technology: Incorporates Fujikura's proprietary Core Alignment technology. Using advanced imaging systems to directly observe the fiber core (rather than the cladding), it ensures precise alignment, resulting in extremely low average splice loss—especially critical for single-mode fibers.

High-Performance Motors: Precision stepper motors enable sub-micron accuracy in X, Y, and Z-axis alignment.

High Splicing Speed

The 28S series is known for its rapid heating and fast splicing cycle. The entire process—from fiber placement to heatshrink protection—can typically be completed in under 30 seconds, significantly improving on-site efficiency.

Superior Environmental Adaptability

Intelligent Windproof Design: Equipped with a large windproof cover and an efficient wind detection system. It automatically adjusts arc parameters to maintain consistent splice quality even in high wind conditions (up to 15 m/s or higher), making it ideal for outdoor use.

Wide Operating Temperature Range: Functions reliably in temperatures from -10°C to 50°C, suitable for harsh climatic conditions.

User-Friendly & Intelligent Operation

Large Color LCD Screen: Provides clear operational guidance and real-time fiber imaging.

Intuitive Graphical Interface: Simple and easy-to-navigate menu design.

Diverse Splicing Programs: Supports single-mode, multi-mode, dispersion-shifted fibers, and more, with built-in optimized profiles for each.

Data Management: Stores extensive splice data (e.g., loss, time, location) for quality tracking and report generation.

Robust and Durable Design

The 28S series is highly praised for its solid metal body and reliable mechanical structure, capable of withstanding bumps and vibrations common in field environments.

Long-Lasting Battery

Includes a high-capacity lithium-ion battery that supports all-day field operation, capable of hundreds of splicing and heating cycles on a single charge.

List of Models and Differences

The 28S series mainly includes the following models. They share the same core splicing capabilities but differ mainly in heating functionality and configurations:

Model Key Features Ideal Use Case

FSM-28S Basic standard model. Includes all core splicing functions but typically lacks a built-in heater. Requires an external heater (e.g., Fujikura FHM-1S) for heatshrink tube protection. Suitable for users with budget constraints or who already own an external heater.

FSM-28S+ The most common and popular model. Includes an integrated heater, enabling seamless splicing and heating in one workflow. Highly convenient and efficient. Most versatile; suitable for the vast majority of fusion splicing applications.

FSM-28S SE “SE” may stand for “Special Edition” or “Simplified Edition”. Configuration may vary by region and batch; may offer slightly simplified functions or special promotions while maintaining core performance. Requires checking specific configuration; often targeted at specific markets.

FSM-28S Micro Optimized for micro fibers (e.g., 250µm and 900µm fibers commonly used in FTTH). Designed with specialized V-grooves, fixtures, and cleavers for higher precision with thin fibers. Ideal for FTTH, indoor wiring, and other applications involving micro fibers.

Note:

All models typically support an optional fiber viewer for inspecting fiber end faces before splicing.

Batteries, chargers, cleavers, and carrying cases are standard or optional accessories.

Conclusion

The Fujikura 28S series is a high-performance, highly reliable fusion splicer that has stood the test of time. Although it is not the latest model, its outstanding overall performance, remarkable durability, and relatively high cost-effectiveness continue to make it a valuable choice in today's market. For users seeking a splicer that can handle various challenges and deliver stable performance over the long term, the FSM-28S+ in particular remains a safe and excellent choice.
