Re: Fibre Installers For others reading/considering this - just FYI, using cat5e between buildings often creates a ground differential during storms which will blow out the ports on the switches attached. Depending on your bandwidth requirements and line of sight, you may want to look at wireless as well, but fibre will definitely resolve the issue too. |

| This is exactly another reason why...blew 3 switches last summer and a UPS.
Shielded cat 6 paired with a vdsl adapter sounds good.
I do have a longer run using RG6 and a pair of these (»www.veracityglobal.com/products/···ire.aspx) that were previously installed by somebody else, but I am extremely disappointed with them. On top of that, the person who installed them did not put grounding blocks so one of the pair was also destroyed last summer. (There are now grounding blocks). Maybe I'll switch to the startech and give that a try. Has anybody used this product?
WIFI is out of the question, too many trees.
How much could a run of fibre this length cost? (disregarding actual network equipment) |

No need for a Ditch-Witch, we got a backhoe on site No matter which way you go, run it through some bright-orange painted conduit. Neither copper nor fibre can survive the John Deere Cable Locator, but the conduit may buy some breathing room.
Been there, done that.

Good NICs and switches have isolation transformers between the cable and electronics which can handle 2-5kV ground potential difference and eliminate the associated common-mode voltage spike so unless there is a lightning discharge through/near the grounding point or building wiring exceeding the transformers' rating, the likelihood of blowing up ports in a storm is low - DSL modems have ~1km of wiring to the DSLAM and millions of them have no trouble surviving thunderstorms.
Cheap equipment on the other hand may use capacitive coupling between chips and wiring, which would send a common-mode voltage spike directly to the chip. Thankfully, equipment cutting such dangerous corners is very uncommon. |
