Two Important Methods for Fiber Optic Splicing

Fiber optic splicing is an important method of joining two fiber optic cables together. It is a preferred solution when an available fiber optic cable is not sufficiently long for the required run. Besides, splicing is designed to restore fiber optic cables when they are accidentally broken. Nowadays, fiber optic splicing is widely deployed in telecommunications, LAN (Local Area Network) and networking projects. Typically, fiber optic splices can be undertaken in two ways: fusion splices and mechanical splices. This paper firstly illustrates the specific process of fusion splicing method and mechanical splicing method, then makes a comparison of the two methods for your reference.

Fusion Splicing Method

Fusion splicing is a permanent connection of two or more optical fibers by welding them together using an electronic arc. It is the most widely used method of splicing as it provides for the lowest loss, less reflectance, strongest and most reliable joint between two fibers. When adopting this method, fusion splicing machines are often used. Generally, there are four basic steps in fusion splicing process as illustrating in following one by one.

Step 1: strip the fiber

The splicing process begins with the preparation for both fibers ends to be fused. So you need to strip all protective coating, jackets, tubes, strength members and so on, just leaving the bare fiber showing. It is noted that the cables should be clean.

Step 2: cleave the fiber

A good fiber cleaver is crucial to a successful fusion splice. The cleaver merely nicks the fiber and then pulls or flexes it to cause a clean break rather than cut the fiber. The cleave end-face should be perfectly flat and perpendicular to the axis of the fiber for a proper splice.

Step 3: fuse the fiber

When fusing the fiber, there are two important steps: aligning and melting. Fist of all, aligning the ends of the fiber within the fiber optic splicer. Once proper alignment is achieved, utilizing an electrical arc to melt the fibers to permanently welding the two fiber ends together.

Step 4: protect the fiber

A typical fusion splice has a tensile strength between 0.5 and 1.5 lbs and it is not easy to break during normal handling. However, it still requires protection from excessive bending and pulling forces. By using heat shrink tubing, silicone gel and/or mechanical crimp protectors will keep the splice protected from outside elements and breakage.

Mechanical Splicing Method

If you want the splices to be made quickly and easily, the mechanical splice is a better choice. A mechanical splice is a junction of two or more optical fibers that are aligned and held in place by a self-contained assembly. A typical example of this method is the use of connectors to link fibers. This method is most popular for fast, temporary restoration or for splicing multimode fibers in a premises installation. Like fusion splice, there are also four basic steps in mechanical splice.

Step 1: strip the fiber

Fiber preparation here is practically the same as for fusion splicing. Just removing the protective coatings, jackets, tubes, strength members to show the bare fiber. Then ensuring the cleanliness of the fiber.

Step 2: cleave the fiber

The process is the same as the cleaving for fusion splicing. It is necessary to obtain a cut on the fiber which is exactly at right angles to the axis of the fiber.

Step 3: mechanically join the fiber

In this step, heating is not used as in fusion splice. Simply connecting the fiber ends together inside the mechanical splice unit. The index matching gel inside the mechanical splice apparatus will help couple the light from one fiber end to the other.

Step 4: protect the fiber

Once fibers are spliced, they will be placed in a splice tray which is then placed in a splice closure. Outside plant closures without use of heat shrink tubing will be carefully sealed to prevent moisture damage to the splices.

Which Method is Better?

Both fusion splicing and mechanical splicing method have their advantages and disadvantages. Whether choosing fusion splice or mechanical splice depends on the applications.

The fusion one provides a lower level of loss and a higher degree of permanence than mechanical splicing. However, this method requires the use of the expensive fusion splicing equipment. In view of this, fusion splice tends to be used for the long high data rate lines that are installed that are unlikely to be changed once installed.

The mechanical splicing is used for applications where splices need to be made very quickly and where the expensive equipment for fusion splices may not be available. Some mechanical fiber optic splice easily allows both connection and disconnection. In this way, a mechanical splice may be used in applications where the splice may be less permanent.

Test Method Fiber Optic

Choose a Test Method.

Once the test cords are verified, you may test the fiber link. There are three options for setting an optical reference between a source and power meter. These options may use 1, 2 or 3 jumpers, or Test Reference Cords. The method used is determined by your regional or vendor-specific requirements. A couple of things should be noted. Optical Loss Test Sets (OLTS) typically have a source and meter at EACH end so they measure two fibers at one time. For simplicity and clarity the graphics here are only showing a simplex setup – one light source to one power meter (except in testing setup with 2 reference cords, that shows both links). When the term “test reference cord” is shown this means a cord with “reference grade connectors”. These are connectors that provide much lower loss than “standard” connectors. Test reference jumpers are more expensive than regular patch cords. A couple of final notes on referencing: Regardless of vendor or model, all optical sources should be allowed to warm up for about 5 minutes prior to performing a reference. On most Optical Loss Test Sets designed for Tier 1 certification, there will be a setting for “reference method”. The physical configuration used to perform the reference MUST match the setting on the test device or your test margins are invalid. So if you set your test setup to do a three fiber reference but what you actually physically do is a one fiber reference, you have a completely invalid test result, especially your test margins are going to be completely invalid. NEVER disconnect the test jumper from the transmitter after a reference is performed – this will destroy the reference – you will need to do it again. Always check your reference by connecting the source test jumper to the power meter test jumper and perform a measurement. There is some variation in what you would expect to see when checking your reference – based on the quality of your test jumpers and the reference method used, certainly below 0.3 dB. One thing you want to watch for when checking your reference is ‘gainers’ – where your test set shows a loss with a positive value, +0.2 dB for example. That is also an indication that you’ve got a bad reference and you’ll need to redo your reference. It is a good practice to save your reference check to have proof that a good reference was established prior to testing. If during the course of testing you question your results, simply check your reference again and re-reference if needed, save the result and carry on testing.
