Whoops sorry to throw you off the trail, mine are single mode. Need more coffee.

As reported by the CCR, tx is -7dbm, rx is -6dbm. (Eric Kuhnke will now scold me and say I should be using SM, but the SFP's with industrial temperature ranges are still a lot cheaper MM.

Tik says fiber is up at 1Gbps but no rx traffic. Netonix detects the cable is plugged in but can’t get any traffic through. Toggling SFP to inactive/active usually fixes. Used Fiberstore Generic, Mikrotik, and HP SFPs in the Mikrotik – no improvements one over the other. Netonix seems to prefer HP SFPs. Doing things like turning flow control on/off or changing speed negotiation settings on the Mikrotik can induce this problem *sometimes* - depends on what mood it’s in. No rhyme or reason when it fails at other times – toggling usually fixes it though.

The SFP interface on the router says there's link, but the SFP interface on the Trango says there isn't. The problem (in my case) occurs any time the Trango loses power. I can restore service by rebooting the CCR, unplugging and reconnecting the fiber cable, or disabling and re-enabling the SFP interface. In this case I didn't have a good picture of what was happening at first because when it was happening I didn't have remote access to see the condition of everything. The Apex Lynx has the JDSU SFP module sold by Trango. I've duplicated the problem with 4 different SFP's in the CCR (Mikrotik brand, Maxxwave, JDSU, and Finisar), but I haven't tried changing the SFP in the Trango. I don't know how common this issue is....it only became apparent after a UPS failed. ------ Original Message ------ From: "TJ Trout" <t...@voltbb.com<mailto:t...@voltbb.com>> To: af@afmug.com<mailto:af@afmug.com> Sent: 10/20/2016 2:30:29 PM Subject: [AFMUG] CRS with sfp lockup I have a mikrotik CRS210 with a non-mikrotik sfp which locked up last night, Not sure if it was the CRS or the sfp... Anyone encountered this and have a solution?
