Splice or Connector, Which to Choose for FTTH Drop Cable Installation?

To choose a right drop cable interconnection solution for FTTH network is very importance. Connectors and splice, as the two common ways to interconnect drop cables, are widely used at FTTH deployment. We all know that the splice can offer a permanent joint, while the connector can be easily operated by hand. But there is a proverb that says you can’t have your cake and eat it too, the providers have to choose between the two. So which should we choose? This paper is going to discuss them in details via talking about their own advantages and disadvantages.

Let’s first go with the splice. Splice is capable of great reliability and can provide excellent optical performance, so that it has been praised highly for many years. What is more, when the connector is not mated, splicing can protect the connector end-face from contaminants that can cause high optical loss or even permanently damage the connector. It just reduces these damages to a minimum. Another advantage of the splice is that it enables a transition from 250 µm drop cable fiber to jacketed cable.

And then let’s talk about its disadvantages. The main drawback of it is the lack of operational flexibility. For example, if you want to reconfigure a drop cable at the distribution point, you should remove one splice, rearrange fibers and splice two new fibers. This requires the technician to carry special splicing equipment for simple subscriber changes. And also, when you are in the process of splicing at the distribution point, you should be careful with the fiber in case of bending or breaking it. If a splice is used at an ONT, there must be space for a tray to hold and protect the splice. This increases the ONT size and potentially the cost.

Unlike splice, connector can provide great operational flexibility in that they can be mated and unmated repeatedly, allowing them to be reused over and over again. When you need to connect a drop cable, you can used the connector to mate without any tools.

Also, connector has its own disadvantages, just as every coin has two sides. The biggest problem of it is the material cost. Therefore, providers must weigh the material cost of connectors along with the potential for contamination and damage against their greater flexibility and lower network management expense.

From the above analysis, now we can draw a conclusion. Splice is more suitable for no fiber rearrangement circumstances, such as greenfield or new construction application. While connector can offer flexibility both at the curb and at the home since it can be plugged and unplugged multiple times.

In a word, drop cable interconnect solution plays an so important part in FTTH network that you should be very careful when you choose the way to do the connection. The right choice will help you to save costs and operate more efficiently. But whether you need a splicer or connector, you can always find it in Fiberstore. For more information, visit FS.COM.
