Fusion Splicing vs. Mechanical Splicing
As we mentioned earlier, there are two main types of fibre splicing: fusion splicing and mechanical splicing. Let's compare them from a time perspective. Mechanical splicing is generally faster, often taking only a few minutes per splice. This is because it doesn't involve melting the fibres together. Instead, it uses a mechanical connector to align and hold the fibres in place. Think of it like plugging in a USB cable — quick and easy.
However, mechanical splices typically have higher insertion loss (signal loss) and are less reliable than fusion splices. They're often used in temporary or emergency situations where speed is more important than long-term performance. Imagine it as a duct-tape fix — it works in a pinch, but you wouldn't want to rely on it permanently.
Fusion splicing, on the other hand, takes longer, but it produces a stronger, more reliable connection with lower insertion loss. The process involves carefully aligning the fibres and then using an electric arc to melt them together. This creates a permanent bond that's much less likely to fail over time. It is like a marriage bond, it will last long time.
So, which one is right for you? It depends on your specific needs and priorities. If you need a quick fix and aren't too concerned about long-term performance, mechanical splicing might be the way to go. But if you want a reliable, high-quality connection that will last for years, fusion splicing is the better choice, even if it takes a little longer.
2. Step-by-Step
Let's break down the fusion splicing process and estimate the time involved for each step. Remember, these are just estimates, and the actual time may vary depending on the factors we've already discussed.
1. Fibre Preparation (5-10 minutes): This includes stripping the coating from the fibre, cleaning it with alcohol, and cleaving it with a precision cleaver. Proper preparation is crucial for a successful splice, so don't rush this step. Like a surgeon carefully prepping for an operation, preparation is key.
2. Splicer Setup (1-2 minutes): This involves turning on the splicer, selecting the appropriate settings, and loading the prepared fibres into the splicer's clamps. Most modern splicers have automatic alignment features that simplify this process.
3. Splicing (1-2 minutes): This is where the magic happens. The splicer automatically aligns the fibres and then uses an electric arc to melt them together. The entire process usually takes less than a minute, but the splicer may run diagnostic tests to ensure a good splice. It is like a robot, that is doing its job properly.
4. Proof Testing (1-2 minutes): After the splice is complete, the splicer will typically run a proof test to verify the quality of the splice. This test measures the tensile strength of the splice and ensures that it meets industry standards. It is like a stress test, and ensuring all requirements are met.
5. Sleeve Application (1-2 minutes): Finally, you need to protect the splice with a heat-shrink sleeve. This sleeve provides mechanical strength and environmental protection. The splicer will typically have a built-in oven that heats the sleeve and shrinks it around the splice. Like wearing a bullet proof vest.
So, in total, the entire fusion splicing process can take anywhere from 10 to 20 minutes, depending on your skill level and the equipment you're using. Of course, this doesn't include the time it takes to access the fibre, set up your work area, and clean up afterwards. But hopefully, this gives you a better understanding of the time involved in each step.
