What are the 7 steps to do the fusion splice?

:: What is a Fusion Splicer?

1. Put on the fusion splice protection sleeve.
2. Strip the fiber. Strip back all fiber coatings down to the 125um bare fiber.
3. Cleave the fiber.
4. Put the fibers into the fiber holders in the fusion splicer.
5. Heat shrink the protection sleeve to protect the splicing joint.

What is splicing discuss any two techniques of splicing?

There are two techniques in splicing of optical fibers depending on the insertion loss, cost, and performance characteristics. They are fusion splicing and mechanical splicing. The mechanical splicing is again divided into two types such as V-grooved splicing and elastic-tube splicing.

How fusion splicing is being achieved?

Fusion splicing is to use high-temperature heat generated by electric arc and fuse two glass fibers together (end to end with fiber core aligned precisely). The tips of two fibers are butted together and heated so they melt together.

How is fusion splicing better than mechanical splicing?

With mechanical splice, the typical insertion loss (IL) is higher—between 0.2 dB and 0.75 dB. This is because the two fibers are simply aligned and not physically joined. Fusion splice offers lower insertion loss and better performance, because fusion splice provides a continuous connection between two fibers.

Can fiber be spliced?

Simply put, fiber optic splicing involves joining two fiber optic cables together. The other, more common, method of joining fibers is called termination or connectorization. Splicing is also used to restore fiber optic cables when a buried cable is accidentally severed.

Can you fusion splice multimode fiber?

Fusion Splicing Most modern fusion splicers recognize the fiber type and will splice single-mode to multimode fiber automatically (without any adjustments to the machine).

What are merits of fusion splicing?

Advantages of Fusion Splicing Fusion splicing offers a lower variable cost per fusion splice. It offers lower insertion loss and provides better performance, typical insertion loss is < 0.1 dB, therefore, it has very low impact on overall link performance.

How much is the power loss of the fusion splice?

Mechanical splice loss is generally calculated in a range of 0.7 to 1.5 dB per connector. Fusion splices are calculated at between 0.1 and 0.5 dB per splice.

What is a fusion splicer used for?

Fusion splicers are used to create long cable lengths by splicing multiple cable segments. Although the splicer will give an estimate of the splice loss, the only way to test it is with an OTDR.

What is pulse width in OTDR?

The pulse width is actually the time during which the laser is on. As we know, time is converted into distance so that the pulse width has a length. In an OTDR, the pulse carries the energy required to create the backreflection for link characterization.

What test capability can be done by OTDR?

The Optical Time Domain Reflectometer (OTDR) is useful for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a “picture” of fiber optic cable when it is newly installed.

What do you need to know about fusion splicing?

There are five basic steps to fusion splicing with a splicing machine. Put on the fusion splice protection sleeve . Strip the fiber. Strip back all fiber coatings down to the 125um bare fiber. Clean the bare fiber with 99% isopropyl alcohol.

Why are multimode fibers harder to fusion splice?

Multimode fibers can be harder to fusion splice as the larger core with many layers of glass that produces the graded-index profile are sometimes harder to match up, especially with fibers of different types or manufacturers.

Why is the splice loss higher when splicing like fibers?

If unlike fibers with differing mode field diameter (MFD) are spliced, the splice loss will likely be higher when when splicing like fibers. The estimated loss from mismatches in mode field diameter (MFD) can be calculated from the following equation:

What causes the lowest splice loss in MFD 9.3um?

Splice loss of fiber with MFD 9.3um is lowest when spliced with any other fiber of range 8.8~9.6um. Core-clad concentricity error, or the amount that the core is off-center from the cladding, can also contribute significantly to splice loss in single mode fiber.
