If you are determined to use conduit, IMC metal conduit will be more durable, but costly. IMC metal conduit is used for plumbing and has threads that can be thoroughly sealed. It is wise to pull twine/string through the conduit with the cable and leave it in place to make cable replacements easier. Cable shielding serves dual purposes. One you likely know about, which is to help prevent EMI/RFI from disrupting your signal in environments that are rife with it. The other purpose is grounding, which is not only key to allowing EMI/RFI to drain off but also allow static electricity to drain off too (ESD). Any Ethernet cable outdoors that is subject to air movement outside, especially when it is suspended in the air, is going to generate ESD - period. A properly grounded cable shield will help prevent damage to your network devices. No, lightning will not be warded off. Lightning will light you and your cable up, and there is no way around that other than also inserting lightning surge protections into the cable run. For high lightning risk installations and environments, that is the only way to go. Minimum trade size recommended is ¾”, and the actual trade size of the conduct you should use is based on the load ratio. See Conduit Fill Chart for Ethernet and Coaxial Cable . An outdoor ethernet cable can connect the outbuilding directly to the router inside a house. The connection will terminate inside the garden building and can be connected to an access point to provide a separate wireless network. Plenum cable is used in spaces generally reserved for HVAC areas, usually under raised floors or above suspended ceilings within buildings. It has special insulation giving it smokeless and low flame characteristics.
A rather detailed and extensive blog with installation examples and recommended hardware is found in When Lightning Strikes! Ethernet Data Cable and Lightning Protection . Tips Even if the water somehow gets inside an ethernet cable, there is a low risk of it becoming a hazard, although there is a very high chance that it will be damaged and you will more than likely see some signal degradation, if it works at all. When you are selecting an exterior wall to drill through, you need to consider several factors. You need to know the location of electrical wires, pipes and plumbing and any other essential services that run through your walls. If you damage any of these services during outdoor ethernet cable installation, you may end up spending far more money on repairs. Something else to keep an eye out for is corrosion if the cable has been left wet for a longer period of time. If you see any, replacing the cable is the way to go.If you need to use shielded Ethernet cable then by all means install it but be aware that shielded cable carries penalties with it, such as: Cold weather won’t affect the performance of exterior-grade ethernet cable as this is simply what they are designed to withstand, but UV exposure is a different story. It may not seem worth spending more money on one of these specialist cables when the length that is being run outside may only be a few feet, but continuing to use the regular ethernet cable you already have is a bit risky, especially if you experience particularly bad weather.
Cold weather can affect ethernet cable, even those that are exterior-grade. Although the cold weather will not affect the performance of the cable itself , it can make the cable stiff. Bending the cable too much could result in damage, so it should be left alone once in place. The cost differences between both have shrunk in recent years and are small. We recommend choosing Cat6 cables to maximise the potential performance and reduce any degradation of the internet connection. If you live in a particular cold part of the world, a valid concern you may is whether the cold weather can affect ethernet cable; even those that are exterior-grade and designed specifically for outdoor use.There are several benefits that come with using the exterior-grade cable, even it is being placed in a conduit and buried. The cable is typically used in offices, homes, schools, and other similar environments. For instance, if you need to connect your PCs to the LAN network, you will run an indoor cable through the ducts to the server room. What is an outdoor Ethernet Cable? If you have an underground rodent problem in your area (moles) your buried Ethernet cable is at risk. It is advisable to use conduit in this circumstance, and preferably metal conduit. The costs are higher, but the benefit is the conduit need not be buried as deeply.
Is it better to put direct burial outdoor cable into conduit or just bury it directly in the ground? A wired internet connection is the best way to achieve fast and consistent performance inside a garden building. The best outdoor ethernet cables provide gigabit speeds for outbuildings where reliably extending Wi-Fi is not possible. However, the 50 feet maximum length makes this cable unsuitable for larger properties and many office and business internet connections. Although, by offering internet speeds of 1 Gbps and a 250 MHz frequency, this cable will provide a solid and dependable connection. You also will not have to worry about connection disruptions with built-in UTP shielding. Best Cat7 ethernet cable: Veetop Flat Cat7 Ordinary and direct burial Cat 6 cables can attract lightning strikes to some extent, and burying the cable alone may not mitigate that risk. To fortify your outdoor ethernet network against lightning strikes and protect indoor equipment, it is advisable to install surge protectors as an integral part of your setup. This precautionary measure will help safeguard your network and valuable devices during adverse weather conditions. Step 1: Choosing A Cable If run in this fashion, a separate messenger wire is required (either velcro tie to a wire with messenger or velcro tie to a stainless steel wire securely fastened to the two structures) Some Common Questions and Direct Answers:Searching for ethernet cables online can often result in lots of different options. To understand the differences, we need to know what the terminology means. Everything from the outer shielding to the internal cable material can be different. As you now know, exterior-grade cable can be safely placed outdoors where it can get wet from the rain, but what about the indoor-rated cables? What happens to them when they get wet?
