Cat 5 limits
I want to run a hard line Cat 5 out to my shop. It will be inside PVC.
What is the limits of length of Cat 5 before you start running into problems? I'd estimate it at 150' run. Steve |

I'm slightly over 300ft and there's slight to considerable degradation unless I terminate with a commercial grade hub at both ends of the run, probably because most PC network cards are kind of whimpy. Plenty of commercial grade hubs still available on ebay though, and for dirt cheap last time I checked--the one I'm using down here is a bay networks 24 port which I purchased second hand and it has been running pretty much continuiously for going on 13 years now. FWIW, you only need two pairs for cat5...so the other two can be used for an alarm system or for telephony if you have land line etc. |

Cat 5 limits
Steve - use CAT 6. It is shielded and an improved 5. I have 100'
string of it from one end of the house to the other and it is running a high speed High Def screen with a gaming program that is extensive. I got 100 blue cat 6 solid plenum patch cable - the plenum means it has a hard wire wrap and then covered. The hard wire allows it to be drawn through hard to pull points or rubbing on a surface... I bought mine from DeepSurplus.com They ship Fed-Ex 2-day if you want. I put a 50' length between our offices - 100Mbps on wire. I just mentioned the place I got it. - Out near Gunner. Laguna Niguel, CA. We are backing off wireless over the house - still to printers and shop. The kitchen did nasty stuff to wireless. I have a switcher-microwave that drops 802.11A,B,G,N out of the air. Cell phone also. Martin On 2/2/2012 2:05 PM, Steve B wrote: I want to run a hard line Cat 5 out to my shop. It will be inside PVC.

Cat 5 limits
Is there electric power half way ? or 1/3...
Run out to that point - put in a switcher - and have the switcher drive the other half. Martin On 2/2/2012 2:05 PM, Steve B wrote: I want to run a hard line Cat 5 out to my shop.

For other installations there is this: http://www.ethernetextender.com/ethe...xtension-kits/ Power over Ethernet runs 48V (like a telephone, but more current) down the cable to power remote devices. The availability of commercial hardware means it could be useful for home surveillance and alternate energy systems, though noncompliant devices could be damaged if you don't observe the rather complex standards. I worked on its R&D. http://en.wikipedia.org/wiki/Power_over_Ethernet jsw |

When the earth rolls on top of you and the driver
isn't up to spec as it should be. Maybe marginal. That is why or maybe he wants to put on on the far end to detect and fan-out for more than one connection.

Steve Like others have said, you are supposed to be able to be able to run cat 5 cable up to 100 meters. At work we have over 60 acres under roof, for long network runs they have boxes that have a Cat 5 RJ-45 connection plus a fiber optic connection, a box like that on each end of the fiber optic gets plugged into the network with cat 5 cables. You probably wouldn't need anything like that but if you found the equipment (2 cat 5 to fiber optic converters and fiber optic network cable) cheap on ebay or something, it would give you a quality connection.

Steve Bit late to your query, but i've done this exact thing with a slighly longer run. I did put a powered hub at both ends. No problems at all in about five year's use. Karl |

Lots of RFI, so I used shielded cable. David |

Cat 6 is what is needed in shielding area. Look it up - it is upgraded.
I added the plenum spec to have a hard wire wrapped and a hard shield over it. That allows pulling it without snagging it on connectors and tearing the impedance out of the wire :-) Martin On 2/5/2012 2:23 PM, David R.
