Re: [AFMUG] Tower Fiber
If you're using Cambium 820 units then you can get the Ceragon armored fiber cables. Single pair, LC connectors, SM or MM, really nice armor, and has the weatherproof gland on it already so you don't have to fight that part. The end is terminated at the right length with the armor and sheath so that it all fits in there neatly. This is what we (DoubleRadius) sell for our 820 links and use in our installs. IP-20_FO_MM_LC2LC_ARM_50m is the P/N, with SM if you want that and 50m length increments. You could also use it for any radio if you slide the gland out of the way.

VCSEL Lasers turned that upside down and single mode is the cheaper one now. The fiber itself costs about the same. There are always exceptions. Last I knew the only "approved" SFP for a Telrad Compact was a multimode one. The device will toss alarms if you put in any other SFP module. and I'll grant you that I last tried a 3rd party SFP about 2 years ago, so this could have changed, but it was definitely true in 2015 & 2016. So all of our Compacts have a multimode fiber cable. Cest La Vie. It was also the case that SFPs with industrial temperature spec were cheaper in multimode. I'm not sure if that's still true, but it was for awhile. -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
