Underwater Data Center Cabling: What Are The Special Requirements For Underwater Wiring?

data, this thing is actually just to bring the messy lines in the data center under the water to link them. Doesn’t it sound quite mysterious? But now many places are used, saying that it can save a lot of electricity! Many people have a lot of questions about what the cables in this underwater data center are and how they are made, just like me. Today I will talk about this.

First of all, we have to talk about some basic situations of this underwater data center. It is different from the ordinary wires and network cables on our land, because they have to be soaked in water, so waterproofing is definitely the top priority! Not only do you need to be waterproof, but you also have to chew the creatures in the waterproof - you think, there are so many fish, shells and so on underwater, what if the thread is broken? And water pressure! The deeper the water, the greater the pressure. The cables must be able to withstand it, otherwise it will be troublesome if they are flat. Therefore, the materials of these underwater cables are solid and good things, which are particularly strong and durable.

So what should I pay attention to underwater? I'll talk about a few key points for you:

1. Cable material selection : This is very important. You must choose a cable specially designed for underwater environments. Some cables have several layers of protective shells on the outside, including plastics, metals, and some even use rubber with particularly stable chemical properties, just to prevent water from entering, and the electrical signals inside from running out, and to prevent corrosion.

2. Installation and fixing method : Underwater is not as easy to operate as on land, and cables cannot be thrown there casually and ignore them. They have to be fixed with a special rack, or sometimes the cables will be buried in the mud and sand at the bottom of the sea, so that you will not be afraid of the ship being cut by, nor are you afraid of the ocean currents rushing it into pieces.

3. Connector processing : Where the cable is connected to various equipment, the connector is the most likely to have problems. The underwater joints must be sealed tightly and there must be no gap at all! There are many waterproof joint accessories now that can protect the joints well. This is technically employed and cannot be careless.

4. Signal transmission stability : Water has much more impact on signals than air, especially those transmitted at high speed. So we have to find a way to reduce the attenuation of the signal when it is transmitted underwater. Sometimes we use that kind of fiber optic cable, which transmits signals quickly and is relatively less affected by water.

Some people may ask: Will this underwater wiring be much more expensive than on land? Well... Generally speaking, when you first started, you would really spend more money on buying special cables and asking professional people to install them. but! In the long run, underwater data centers can not save a lot of electricity bills, because water can help dissipate heat, and air conditioners can save some electricity. This way, over time, the cost can be compensated. Some people also asked, if the cable is broken, will it be convenient to repair it? This is indeed quite troublesome. You have to send divers down or use an underwater robot to repair it. It is definitely not as simple as climbing a ladder on land to repair it. Fortunately, technology has been improving now. Many times, through monitoring, you can find out whether there are any problems with the cable in advance, and you can also deal with it as soon as possible. Furthermore, compared with ordinary undersea communication optical cables, what is the difference between underwater data centers? Submarine communication optical cables are mainly used to transmit data remotely, with a very long distance; while underwater data centers are mainly connected between various equipment inside the data center, or the data center is connected to nearby infrastructure, which is relatively close, but the transmission speed between the equipment is required to be fast and the delay is low.

I personally think that although this underwater data center sounds troublesome, it is indeed a promising technology. As we use more and more data, the energy required by the data center is getting bigger and bigger. Putting them in water and using the advantage of water to dissipate heat is very good! As long as the quality of the cable is kept in place, the installation and debugging are more carefully, and the maintenance is more effective in the future, there should be no major problems.
