Unbelievable. The same thing happened to me at a restaurant in West Point, Georgia. In that case the waitress explained that the Budweiser plant was only an hour away. So an hour away counts as local in the US, and Georgia doesn't know what local beer is.

We're a bit weird; people are measured in feet/inches and pounds, but we'd buy 400 grams of ground beef, not a pound. Short distances tend to be given in kilometers, long distances in approximate travel time. A standard can of beer is 355 millilitres, but a shot is 1.5 oz. We all have one set of wrenches in metric, and one in imperial. It's 19 degrees C outside, but I'm going to preheat my oven to 350f. We tend to think of baking recipes in terms of cups, tea or tablespoons or whatever, but we also tend to know that a teaspoon is 5 ml, a tablespoon is 15 ml and a cup is about 237 ml, but we're also big believers in measuring such things by weight, not by volume. Speedometers tended to have both metric and imperial until relatively recently, and many of us still decipher American speeds because we know that the 55 mph pretty much lined up with 100 kph. Also, in Canada, milk comes in bags, and 'a pint of beer' is legally defined as 20 fl oz, or 568 ml, with an allowable error of +/- .5 ml, and it's legally enforceable. We do not, however, have the equivalent of reinheitsgebot. And Stella Artois is still considered 'import' despite being bottled in Quebec.

Canada used to sell gasoline by imperial gallons (do they still?) which are more than one US gallon. I sometimes refer to our system of measure as imperial units but that fails with imperial gallons.

There is a lot of variability in velocity of propagation, earth temperature, splice slack loops, fiber twist. 1 mile error over 50 miles is only 2%. You can easily be off by several thousand feet. You can't just go dig. You have to go to the closest splice point and test again, even then if you it show the fault 2000 feet away and you dig at 2000 feet you may be off by 20 feet or more.

In some instances with dirty connector at just the right connector you can get reflection back in to the transmitter that can cause errors, the tx to shut down or premature failure. This is very uncommon with LR 10G and less optics and can be prevented from making sure you have clean connectors. Check the RX and TX levels and make sure you don't have excessive loss. With 100G its a little different story due to the combined power of multiple channels, but still can be prevented by cleaning connectors, but in some instances Ive had to use attenuation when mixing different vendor optics. The using no launch on an OTDR most automatically calibrating OTDRs will work without one. Your results can be off though. Most of the lower cost ones are also lower powered and have less of an RX sensitivity so they don't suffer as much from the reflections interfering when testing. I can test all day long with my little otdrs without one, but my long range 200k+ units I have to have a minimum of a 1k spool on it or you see ghosts. They will show up as repeating events at even intervals. Not something you will see on shorter runs either.

I have been using 1 meter cables and they are almost always too long, I'm talking about going between routers and switches in a rack, stuff like that. I see that FS sells 0.5 meter cables, but I saw somewhere like maybe on Reddit someone claiming there was a minimum length. Given SM fiber and LR optics, I don't see how 0.5 or 1.0 meter would be different they are both essentially zero length. Probably there's some kind of cable tray or cable management solution I could be using but I've never liked such things. -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com _____ -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com _____ -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com _____ -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com _____ -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com _____ -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com _____ -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
