Hey there! As a supplier of indoor FTTx fiber optic cables, I often get asked this question: Can indoor FTTx fiber optic cable be buried? Well, let's dive into this topic and find out.
First off, let's understand what indoor FTTx fiber optic cables are. These cables are designed specifically for indoor use in Fiber to the Home (FTTH) or Fiber to the Building (FTTB) networks. They're used to connect the optical network terminal (ONT) inside a building to the optical distribution network (ODN) outside.
Indoor FTTx cables come in different types, like the Micro Double Jacket Cable, Round Duplex Optical Cable, and MPO Patch Cord Cable. Each type has its own features and is suitable for different indoor applications.
Now, back to the main question - can they be buried? Technically, you can bury indoor FTTx fiber optic cables, but it's not a good idea in most cases. Here's why.
Environmental Considerations
Indoor cables are not built to withstand the harsh conditions underground. The environment underground is full of moisture, soil chemicals, and physical stresses that indoor cables aren't designed for. Moisture is a big enemy of fiber optic cables. It can seep into the cable, causing corrosion and signal loss over time. Soil chemicals can also react with the cable materials, degrading their performance.
For example, if the soil has a high acidic or alkaline content, it can eat away at the cable jacket. And let's not forget about physical stresses. When you bury a cable, it has to deal with the weight of the soil above it, as well as any movement in the ground due to things like tree roots growing or ground shifting. Indoor cables are usually more flexible and thinner, which makes them more vulnerable to damage from these physical forces.
Safety and Compliance
Another important factor is safety and compliance. Indoor cables are typically rated for indoor use only. They don't meet the safety standards required for underground installation. For instance, they may not have the proper fire - retardant properties or be able to resist rodent damage, which is a common problem underground.
If you bury an indoor cable and there's a problem, like a fire or a rodent chewing through it, you could be in violation of local building codes and safety regulations. This could lead to fines and, more importantly, put people at risk.
Cost - effectiveness
In the long run, burying indoor cables is not cost - effective. Since they're more likely to get damaged underground, you'll probably end up having to replace them more often. This means more money spent on new cables and the labor to install them. On the other hand, outdoor - rated cables are designed to last in the underground environment, so you'll have fewer maintenance and replacement costs over time.
When Burying Indoor Cables Might Be Okay
There are some situations where burying indoor FTTx cables might be acceptable. If you're doing a short - term or temporary installation, and the burial conditions are relatively mild. For example, if you're setting up a temporary network for an event in a dry, stable area with no significant physical threats. But even in these cases, you should take extra precautions, like using a protective conduit to shield the cable from the elements.
Alternatives to Burying Indoor Cables
If you need to run a cable underground, it's much better to use outdoor - rated fiber optic cables. These cables are specifically designed to handle the underground environment. They have thicker jackets, better moisture resistance, and are more resistant to physical damage.
You can also consider using a combination of indoor and outdoor cables. Run the outdoor cable from the source to a point near the building, and then connect it to an indoor cable inside the building. This way, you're using each type of cable for what it's best suited for.
Conclusion
So, to sum it up, while it's technically possible to bury indoor FTTx fiber optic cables, it's generally not a good idea due to environmental, safety, and cost - effectiveness reasons.
