How to Use Fujikura 90S+ Core Alignment Single Fusion Splicer Splicing Time 7 sec Heat time with CT50 Fiber Cleaver: Complete Guide

Step 1: Initial Setup and Installation

Start by placing the machine on a stable surface using the provided work trays. Install the battery pack fully until it clicks. Connect the AC adapter for initial charging or if you are working near a power source. Turn on the power switch located on the side. The system will run a quick self-diagnostic and then be ready.

Step 2: First-Time User Guide

The interface is a 5.0-inch color touchscreen that is intuitive. You can navigate through the menu using the touchscreen or the physical buttons. Before your first splice, set the fiber type (SM, MM, NZDS) in the settings menu. The fiber discrimination function can be set to automatic for convenience. Check the electrode status and perform an arc calibration test if it is your first time using the machine or after a long transit. This ensures optimal arc power for your local conditions.

Step 3: Core Functions and Daily Use

Load your prepared fibers into the fiber holders. With the 90S+, you will notice the automated features. After you place the fiber and close the lids, the machine starts the alignment and splicing process automatically if you have set it to auto-start. The crucial feature here is the fiber retention clamps. After the splice is complete and the sheath clamps open, the fiber retention clamps hold the spliced fiber in place, preventing it from flying out. To remove it, simply lift the fiber up, and the clamps release. This reduces fiber breakage and accelerates the process. The heat time is equally fast, making the overall cycle time very short.

Step 4: Advanced Techniques

Experienced users can take advantage of the programmable splice and heat modes. You can fine-tune the arc power, prefusion time, and offset settings for specialty fibers or environmental conditions. The machine also allows for fiber image data storage and transfer via USB for quality control reporting. Pro tip: the fiber discrimination function is a huge time-saver, but always verify the selected fiber type on the screen before splicing, especially when working with non-standard cables.

Step 5: Maintenance and Care

Clean the V-grooves and mirrors after every 50 to 100 splices using the provided VCB-01 brush and a lint-free swab with alcohol. Replace the electrodes after approximately 3,000 arc counts. The machine will prompt you when a replacement is needed. Always store the splicer in its included carrying case with the drying desiccant in a dry environment to prevent lens fogging.

Step 6: Troubleshooting Common Issues

If you encounter high splice loss, first check for dirty V-grooves or electrodes. If the machine fails to splice, ensure you are using the correct fiber holders for your fiber type.

Performance & Real-World Testing

Testing Methodology

We tested the Fujikura 90S+ over a four-week period across two different job sites. We performed over 500 splices on standard single-mode fiber, loose tube fiber, and 250-micron bare fiber. We used the included CT50 cleaver and standard 60mm protection sleeves. We timed the entire splice-to-heat cycle and measured splice loss using a standard OTDR and an insertion loss test set.

Performance Metrics

The splicing time of 7 seconds is accurate in our testing, with the heat time for the 60mm sleeve averaging around 18 seconds. The total splice cycle (from lid close to ready for next fiber) was approximately 30 seconds. Splice loss was consistently below 0.02 dB for single-mode fiber, which is excellent. The core alignment algorithm handled fibers with slight eccentricity issues without increasing splice loss, proving its value as the best core alignment splicer in this price range.

Real-World Scenarios

In a data center environment with tight cable trays, the work tray configuration was particularly useful. We split the tray to fit into a confined space. The automatic sheath clamp opening was a time saver. In a field environment with loose tube fiber, switching the sheath clamp protrusion was seamless and did not require any tools. The machine handled temperature variations without needing recalibration.

Claims vs. Reality

Fujikura claims the fast automation reduces installation times. Based on our testing, we saw a productivity increase of about 15% compared to a standard 9-second splicer, primarily due to the retention clamps and auto-open features. The only minor gap we noticed is that the battery life, while sufficient for a standard workday (approximately 200 cycles), may require a spare for very heavy days. This performance data is critical for anyone making a Fujikura 90S+ fusion splicer buy decision.
