  A fiber splicer installs, repairs, and maintains fiber optic wires that are used in high-speed communications. A professional uses a number of specialized tools such as fusion splicer ,fiber cleaver, fiber connector to cut, connect, and test wires. He or she usually receives specialized training on how to diagnose problems with cables and make delicate repairs.
 An expert fiber splicer might work in a consumer electronics manufacturing plant as an assembler and installer, or a communications company, such as a cable television and Internet provider, as a fiber optic technician. Optical fibers are minuscule wires made of glass or plastic that are capable of transmitting massive amounts of information through pulsations of light. The process of splicing fibers together involves carefully cutting and exposing bare fibers, then joining the ends using specialized crimping tools, glues, and precision arc welders. Bundles of fibers are usually wrapped together into a cable and insulated with a moisture-proof sheath. Professional fiber splicers frequently attach adapters on the ends of finished cables so they may be plugged into computers or other electronic devices. Professionals who work in manufacturing plants prepare, cut, and splice fiber optic cables for use in consumer electronics, computers, and other commercial devices.
 Fiber splicers might arrange fragile wires, weld or glue pieces together, and aid in their installation and assembly into various products, such as wireless adapters and sensors. They also prefabricate couplers and joiners, and insulate cables for use in large-scale communications.
 A fiber optic technician at a communications company may specialize in splicing and installing cables inside homes and businesses or maintaining outdoor and underground lines. A fiber splicer must be able to accurately measure lines, cleave them at the appropriate place, identify individual fibers based on their color and arrangement within a cable, and splice them with auxiliary fibers that attach to computers, wireless routers, and cable outlets

  The global consumption value of fiber optic fusion splicer in 2008 was $300 million. The consumption value is forecast to increase to $470 million in 2013, with strongly rising quantity growth partially offset by a continuing decline of average prices. ElectroniCast’s global forecast of fiber optic fusion splicer, in terms of the number of units (quantity/each) and average selling prices (ASPs) are also presented.   
 This report provides the historic year of 2008 and a 5-year (2009-2013) forecast of the consumption of fusion splice machines (fusion splicer), segmented into the following geographic regions: North America, Europe, Asia Pacific Region (APAC), Rest of the World, plus Global summaries.

Before optical fibers can be successfully fusion-spliced, they need to be carefully stripped of their outer jackets and polymer coating, thoroughly cleaned, and then precisely cleaved to form smooth, perpendicular end faces. Once all of this has been completed, each fiber is placed into a holder in the splicer’s enclosure. From this point on, the fiber optic fusion splicer takes over the rest of the process, which involves 3 steps:

 

• Alignment: Using small, precise motors, the fusion splicer makes minute adjustments to the fibers’ positions until they’re properly aligned, so the finished splice will be as seamless and attenuation-free as possible. During the alignment process, the fiber optic technician is able to view the fiber alignment, thanks to magnification by optical power meter, video camera, or viewing scope.

• Impurity Burn-Off: Since the slightest trace of dust or other impurities can wreak havoc on a splice’s ability to transmit optical signals, you can never be too clean when it comes to fusion splicing. Even though fibers are hand-cleaned before being inserted into the splicing device, many fusion splicers incorporate an extra precautionary cleaning step into the process: prior to fusing, they generate a small spark between the fiber ends to burn off any remaining dust or moisture.

• Fusion: After fibers have been properly positioned and any remaining moisture and dust have been burned off, it’s time to fuse the fibers ends together to form a permanent splice. The splicer emits a second, larger spark that melts the optical fiber end faces without causing the fibers’ cladding and molten glass core to run together (keeping the cladding and core separate is vital for a good splice – it minimizes optical loss). The melted fiber tips are then joined together, forming the final fusion splice. Estimated splice-loss tests are then performed, with most fiber fusion splices showing a typical optical loss of 0.1 dB or less.

Nanjing Jilong Optical Communication Co., Ltd is professional in developing and producing Fusion Splicer.

The process of fusion splicing involves using localized heat to melt or fuse the ends of two optical fibers together. The splicing process begins by preparing each fiber end for fusion. Fusion splicing requires that all protective coatings be removed from the ends of each fiber. The fiber is then cleaved using the score-and-break method. The quality of each fiber end is inspected using a microscope. In fusion splicing, splice loss is a direct function of the angles and quality of the two fiber-end faces.

The basic fusion splicing apparatus consists of two fixtures on which the fibers are mounted and two electrodes. Figure 4-13 shows a basic fusion-splicing apparatus. An inspection microscope assists in the placement of the prepared fiber ends into a fusion splicer. The fibers are placed into the fusion splicer, aligned, and then fused together. Initially, fusion splicing used nichrome wire as the heating element to melt or fuse fibers together. New fusion-splicing techniques have replaced the nichrome wire with carbon dioxide (CO2) lasers, electric arcs, or gas flames to heat the fiber ends, causing them to fuse together.

Optical fiber fusion splicing is a welded joint formed between two optical fibers. It is a permanent, low-loss, high-strength joint compared with other temporary joint such as a mechanical splice. Optical fiber fusion splices play a crucial role in the optical network.

 

The Ideal Fusion Splicing Process

The goal is to create a joint with minimum insertion loss yet with mechanical strength and long-term reliability that matches the fiber itself.

The ideal process should be fast, inexpensive and should not require expensive equipment. But in reality the process needs trade-offs among different applications and requirements. For example, for undersea telecommunications, long-term reliability is the most important goal for a fusion splicing.

The Advantages

There are other approaches for interconnecting fibers such as fiber optic connectors and mechanical splicings. Compared to these two, fusion splicing has many advantages as explained below.

1. Very compact

2. Lowest insertion loss

3. Lowest back reflection (optical return loss ORL)

4. Highest mechanical strength

5. Permanent

6. Can withstand extreme high temperature changes

7. Prevents dust and other contaminants from entering the optical path
