Fiber Optic Fusion Splicer Mode

Adjusting the splice mode on a fusion splicer allows you to optimize splicing for different fiber types, including single-mode, multimode, and specialized fibers, ensuring high-quality, low-loss connections.

Understanding Splice Modes

Fusion splicers typically offer several modes: Automatic Mode (Auto Mode): The splicer detects the fiber type and automatically adjusts parameters like arc power and heating time. Ideal for beginners or bulk installations where speed is important (INNO splicers). Manual Mode: Provides full control over arc intensity, splice time, and fiber alignment.

Useful for repair work, testing, or non-standard fiber types.

Single-

Mode (SM) Mode: Optimized for single-mode fibers with small core diameters, ensuring minimal signal loss for long-distance networks. Multimode (MM) Mode: Tailored for multimode fibers with larger cores, adjusting arc power and alignment for optimal results. Some splicers, like the Fujikura 70S+, also include AUTO sub-modes such as SM AUTO, MM AUTO, NZ AUTO, and DS AUTO, which automatically calibrate the arc for specific fiber types.

Step-by-

Step Guide to Adjusting Splice ModeCheck the Current Mode: The active splice mode is usually displayed on the splicer's screen. Verify it before making changes. Access the Splice Menu: Press the or [Splice Mode] button to open the list of available modes.

Select the Desired Mode: Highlight and select the appropriate mode for your fiber type (e.g., Single Mode for SM fibers, Multimode for MM fibers). Confirm the Selection: The chosen mode will appear on the screen. Press or to return to the main interface and begin splicing.

Optional Parameter Adjustment: For specialized fibers, you can manually adjust arc current, splice time, or alignment settings and save custom modes for future use.

Tips for Optimized Splicing

Use Auto Mode for Standard Installations: Saves time and reduces errors for routine splicing tasks. Switch to Manual Mode for Repairs or Uncommon Fibers: Allows precise control over splicing parameters. Save Custom Settings: If you frequently work with non-standard fibers, saving custom modes can streamline workflow.

Follow Safety Guidelines: Ensure proper power supply, avoid touching the splicer during operation, and follow manufacturer instructions to prevent damage or injury. By selecting the correct splice mode and adjusting parameters as needed, you can achieve high-quality, low-loss fiber connections suitable for telecommunications, data centers, and FTTH deployments.
