whats the longest run i can go ?
and is there a underground type of rj45 cable ?

im thinking of running it out to my work shed . its have to be a single 150 ft run . is this a possible idea
also on the same note.
im thinking of running cable tv out there and i have to do the same as with the rj 45 .

any one done this or know if it can be run that long with out loss of signal off my router ?

i have PVC run underground now I'm thinking of running it in. but it has 3 lengths of #6 electrical wire run in it .its under ground rated wire . will this be a problem for the rj-45 or rj-6 cable .in terms of power problems ? like affecting signal . it is running the power out to the shed ! its all on a 40 amp 220 circuit breaker ! .
the PVC pipe is 1.25 so thats not a problem room wise to add the cables if they don't have a problem being this close to the home current. 110/220 volt wires there already .
will this be a problem .

A google search showed that you can have a run of 100 meters (328 feet). Could you use a wireless router instead of running cable?

No underground CAT5 that I've ever seen.

Yes, 100M is the thoretical limit - real world is closer to 50-75M. However, that's within your 150 ft.

YES - you will likely get interference from your power cable if you're running them in the same conduit. You can:

1) give it a try - you may still get a signal, but it'll probably be 10Mb rather than 100. If you're just surfing the web, this could be OK.
2) try a sheilded cable (STP) - this will protect the cable from the electrical interference, but it's expensive & hard to find
3) as Hoser suggested, go wireless

I would either go wireless or put down a new conduit with Cat 6 cable. Hey, if your are gonna put it under the ground you might as well future proof a bit.

I wouldn't try to run a cable along with the power lines. For that length the risk of intereference killing the signal is way too high.

You should always maintain a minimum 3' clearance between data and power cabling to avoid EMI from the power cables. If you have to cross a power conduit with data cabling, you should do so perpendicular to the power cabling to minimize EMI.

As for underground utilities, you must run your data/voice/video low voltage cabling in a seperate conduit from your power cabling (National Electrical Code). If you live in an area that is prone to lightning you will have to install a fused protection entrance panel at either end to protect either building from an electrical strike.

I would not, under any circumstances, ever put data and power cabling together. Since you have a 150' run, there is a very good chance of stripping the wire jacketing and exposing either the data or power wires due to friction from pulling that wire alongside the other active wiring. Just think of the possibilities there for a minute... 220v, 40A... a very dangerous combination for both your equipment and you if you are terminating a shorted lead and you are the path to ground.

ya i just desided it was a bad idea and will be going with out internet/tv in the shed/garage !

well the yahoo that installed the panduit in my computer lab ran power and data cables togeather and there are outlets and rj45 pannels one above the other around the permiter of my lab probably a 40ft runs each on 2 walls and then probably 80ft from the closet and even though that is not the correct way of doing it it was still dont that way and works great

you cuold save on conduit and get a Direct burial cable
http://www.cat5ecableguy.com/outdoor_bulk_cable?b=1
Several types of Outdoor Bulk Cable:


1. UV- Rated
2. Outdoor Shielded w/ drain wire
3. Direct Burial ----Tape wrap
4. Direct Burial ---- Poly Gel Filled

or this is the coolest thing ever CABLE TV over CAT5 Cableing

Kevster

That will work fine as well. Direct burial is a little more time-consuming to terminate because of the gel blocking kit you have to do at each end, but it is definitely a viable alternative. If just means that Renovation will have to trench a path to bury that cable first.

Kevster

Multimedia cabling like that has been around for a long time, though I never saw it in the commercial/industrial projects I worked on.
