Re: Connecting two houses via ethernet (electricians welcome!)said by billaustin:Ethernet does not reference ground, and does not pass voltage (unless you are using POE). If it is shielded cable, which is not necessary, the shield should only be grounded at one end. Ethernet cable does not create any grounding issues between structures, unless shielded cable is used and grounded at each end.
The proper thing to do is use an Ethernet surge protector at each end of the cable where it enters the structure. The surge protector should be grounded, and that ground needs to be bonded to the structures electrical ground. This is easier to accomplish if the entry point is near the main electrical panel.
That being said, I have buried Ethernet cable connecting multiple buildings. The longest run is around 160 feet. I installed it about 17 years ago, without proper protection at each end, and it has run without issue. I upgraded the switches to gigabit, a couple years ago, for better performance. What billaustin says here is correct. You are only 120 feet apart. Ethernet can be run much longer than that. IMHO, fiber is a waste in this situation. The trench is already dug. Just run the ethernet and be happy with the gigabit speeds that they provide. I ran ethernet for my father in law to his pole barn that is 150 feet away from his home. We dug a trench, used PVC pipping and successfully ran the cable. He has a single gigabit connection going into the barn, which he splits out using a 5 port gigabit switch. He doesn't use an ethernet surge protector, and the cable run has been good for 10 years. What makes the run good and why it stays good is the pvc pipping we ran the cable through and buried underground. Don't concern yourself with fiber. You will be happy with copper. |

said by Nightfall:fiber is a waste in this situation. To be safe he will need to place protectors on each end $80+ for both as well as an extra or 2 so another $40-80 or have 2 switches, as well as 2 sitting and waiting to go in, on either side to act as protectors and hope that the switch fries before it gets to other devices. At under $200 not not have to worry about losing several hundred\thousand worth of devices and then pull fibre after the second time it happens is not a waste. I have had to repair an office this happened to just a few years ago. The switch on either end did not stop the surge and it killed several devices, including a server, a 4 port NIC in a ESXI box, 3 printers, a couple PCs the switches of course and a wireless access point. So dont count on the switches to stop the surge. And no I still haven't pulled new fiber. |

I know that you can spend $15 total. » www.newegg.com/Product/P ··· -ProductI have a friend who has something like these he spent $8 each for. Personally, I have never had a surge issue on ethernet because I don't run POE devices. At the same time though, if you want a little insurance, it doesn't cost $80+ to get protection. In the end, copper is going to be more cost effective than fiber. |

POE is not the issue. said by Nightfall:In the end, copper is going to be more cost effective than fiber. Right up to the point where it isn't. If you never have a lightning strike close enough then your right. But whats a $100 insurance. Just giving options, if you are OK with what you have then my posts are not relevant to you. The OP might find the info responsive. said by tomdlgns:H_T_R_N (or anyone else) does code allow you to run cat 5/6 in the same PVC conduit? if so, i'd run the cat5 along with fiber just to have it available... Here it is permitted, other locations I can't speak to, but could not see what the reason would be not to allow. |

Just giving options, if you are OK with what you have then my posts are not relevant to you. The OP might find the info responsive. Very true. I was merely pointing out that inflating the cost of protective hardware like you did was really not the way to get your point across. Being as that if you are very nervous about a lightning strike, you can get the hardware you need for $15 for both ends that will protect you. Its great to have options, no doubt about it. |

said by Nightfall: Just run the ethernet and be happy with the gigabit speeds that they provide. Hell, run Cat6a and you could always upgrade to 10GBASE-T (10 gigabit) down the road, when the switches aren't so astronomically expensive. Or, run multiple drops, stay gigabit, buy a couple of relatively cheap ($300) Procurve switches, and run LACP for link aggregation. |
