Fiber-Optic Fusion Splicers

Fusion splicers are an important tool for technicians who work to maintain fiber networks. Proper calibration of these devices can enhance network performance and minimize signal loss.

To begin with, the splicer strips away the cable jacket and coating of the fiber ends before a pre-fuse cycle heats them up and removes any dust or dirt from the ends. Then, an automated electric arc process welds the ends together.

Core Alignment

Using small, precise motors, core alignment fusion splicers make minute adjustments to the positions of two cleaved fibers before they fuse together. This ensures that the finished splice is seamless and attenuation-free. Technicians can monitor this alignment with magnification, such as an optical power meter or video camera.

Optical fibers have different refractive indexes in their cladding and core, and this affects their brightness intensity profile. With core alignment fusion splicers, the machine recognizes this and aligns the cleaved ends of the two glass fibers. This process is especially important for active FTTH networks, which require high bandwidth and low latency for a seamless user experience.

The best way to achieve this is by utilizing precision fusion fiber-optic-fusion-splicers splicers that feature high-resolution imaging and automated alignment capabilities. This minimizes maintenance costs and signal loss, resulting in cost efficiency for service providers.

Moreover, core alignment splicers are also highly reliable and consistent. Their performance is enhanced by using precision cleavers, conducting proper fiber preparation, implementing calibration and verification routines, and leveraging human expertise to perform splicing tasks. This enables them to deliver on their promise of exceptional bandwidth and connectivity. Furthermore, by ensuring impeccable alignment, FTTH service providers can achieve a superior customer experience and stay competitive in today’s broadband market. This is the key to enabling customers to achieve their highest broadband speed and meet growing consumer demand.

Cleanliness

When it comes to maintaining fiber-optic splicing equipment, the old adage “cleanliness is next to godliness” has never been more true. A dirty fiber splice can cause a variety of problems, including signal loss and outages. Therefore, a clean, reliable splice is crucial to the future of our interconnected world.

Before inserting the fibers into a fusion splicer, it’s essential to prepare them properly. This includes stripping the fibers and cleaning them. This allows for precise alignment and lower splice loss. The stripping process should be performed in a controlled environment. It is important to use a precision stripping tool and follow the manufacturer’s guidelines for stripping. This will ensure that all of the protective polymer is stripped and the bare glass surface is exposed. During the cleaning process, it’s important to use lint-free fiber optical grade cleaning wipes and an IPA (isopropyl alcohol) substitute specifically engineered for cleaning fiber. This alternative evaporates much faster, which saves time and prevents contamination from moisture-related issues.

Once the fibers are prepared, they can be inserted into the fusion splicer and aligned. The splicer then uses an electric arc across the opposing ends of the fibers to fuse them together. The spliced end is then covered with a heat-shrink sleeve to protect the fiber from dirt and moisture. It is also important to regularly monitor the spliced end for splice loss. This will allow for prompt troubleshooting and rework when needed.

Safety

Regardless of the type of fiber fusion splicer used, there are certain maintenance requirements that must be followed. This includes regular cleaning and the replacement of electrodes. These electrodes are the heart of the splicer, and they emit an electric arc to fuse optical fiber ends together. They can wear down after a certain number of arcs, so it’s important to follow manufacturer recommendations for replacing them.

Performing this task requires precision and skill. It’s also important for technicians to adhere to safety protocols and wear personal protective equipment. This ensures that they are protected from injuries and other hazards while working on FTTH fibers. It also helps them maintain network reliability for end-users by minimizing downtime due to accidents.

Once the technician has cleaved the fibers with a special cleaver, they must align them in the splicer. This step is critical, as it will ensure that the spliced fibers are seamless and low-loss. The technician can use a fiber power meter or video camera to see the alignment, and some devices even provide index matching gel for splicing.

Once the alignment is complete, the splicer will generate a second arc to melt the cladding and core of each fiber together. The device will then create a heat weld that’s strong enough to prevent moisture and other environmental contaminants from damaging the splice. Once the splice is complete, the splicer will emit a beep and then apply a heat-shrinking sleeve to the fiber end.

Efficiency

Fusion splicers allow technicians to make permanent connections with fiber optic components less loss than mechanical splices. This allows for more efficient data transfer, reduced latency, and higher overall connectivity. Fusion splicers are also more tolerant of environmental conditions than mechanical splices, such as wind and dust.

The efficiency of a fusion splicer depends on several factors, including the cleaver used to prepare the fiber ends, the core alignment system, and the training and skill level of the technician using it. Proper cleaving and cleaning of the fiber ends is essential for achieving low splice losses. During the splicing cycle, the fusion splicer uses either a core or cladding alignment to align the fiber ends before applying heat. Core alignment splicers are more precise and recommended for single-mode fiber, which has a small core diameter.

More basic fusion splicers use a fixed V-groove to line up the fibers for splicing. The splices are then bonded together with a plastic snap-type cover. This type of splice is usually considered temporary, and the loss caused by a mechanical splice is much lower than that of a fusion splice. It is important to note that a proper splice requires the endface of the optical fiber to be free from any surface defects and the splicing angle to be within the range stated by the manufacturer.
