I have Time-Warner cable internet and TV service in my home. I am moving my home office to my newly remodeled workshop approximately 175 ft away from the existing cable modem (so maybe 225ft of cable needed). I need the best internet signal possible in the office but I don't need TV at the office. Time-Warner will not provide internet service or a 'drop' at the workshop (long story...).

So, which of these should I do?

Run 225ft of coax (with cable signal) to the workshop first, then cable splitter, run 225ft of cable back to the TV in house, run short cable to the modem and router in workshop, then from router to computers and printers.

OR

cable splitter first, short cable to modem in the house and other cable to TV in house, then from modem in the house run 225ft of cat5/cat6 to workshop, then to router in workshop, then from router to computers and printers.

OR
something else?

In other words, run 225ft of cable signal or the internet signal?

If I need an amplifier (or booster, ext. cables, etc) do they work better with cable signals or cat5/6 signals?

Please let me know what gets the best internet signal. Not too worried about the TV signal back at the house

Thanks
Tony

There are issues running power and data in the same pipe. I suspect you could run the ethernet and the 110 power in the same pipe and it would not cause you interference but nobody does it. Not so much because of the data concerns but because of the electrical codes. Most time the answer is this is not allowed but there appear to be some exception that only a expert electrician can decode. Ethernet is consider low voltage cables in the electical codes and is treated like phone,alarm,tv cables.

Pretty much the common way to do this is to put the power at 12 to 18 inches down (depends on local code and type of conduit). Then run the other cables at 6inches. This seems to meet most codes. It of course is well beyond any EMI...

The ethernet from the modem to the remote location over cat5e will work for sure. The coax might work but it will depend how much signal level you have from the cable company. In effect you are adding the 225ft of cable to the ISP cable coming from the street.

I would use the ethernet option since it is guaranteed to work since you are well withing the 100 meter ethernet limit

all good suggestions, thanks so much

makes sense, will do

I am running watertight PVC conduit underground because I want to to also share telephone and a 110v generator with the house. We have a lot of other digging/landscaping to do, so easy.

bill001g,

True, good point. In the unlikely event there's a power outage I will not likely be running any computer hardware anyway. And I may not send any power to the house unless the outage lasts a long time, again an unlikely event - but can happen of course.

In light of your suggestion, I may just continue to run the extension cord to the house instead, when needed. That's what we did (in reverse) before the electric was installed in the workshop - so already have heavy duty cord ready to go.

Thank you, that would be safer solution also.
