I will say, I really like the UBNT ONT, and I've been thinking of offering it as a premium option because of the display. Having the ability to show usage easily is very nice. I just feel UBNT missed the price mark here, and missed the opportunity to do something big like ngpon2 with 40gb/s capacity capabilities. That would have rocked the manufacturers. Gino A.

Some can do a 2-3db depending on the product, but it's never really a truly intelligent system with bidirectional communication between the optics to negotiate power levels. I may be wrong but this is just my experience. On Aug 2, 2017 12:26 PM, "Josh Reynolds" <j...@kyneticwifi.com<mailto:j...@kyneticwifi.com>> wrote: How could they? TX and RX are different optic sources. You might have a TX power level much higher on one end than the other due to manufacturing differences or different equipment.

Most of my SMF lasers and links are short and 'hot', but doesn't seem to bother anything I'm currently using. -----Original Message----- From: Af [mailto:af-boun...@afmug.com<mailto:af-boun...@afmug.com>] On Behalf Of Brett A Mansfield Sent: Wednesday, August 2, 2017 10:16 AM To: af@afmug.com<mailto:af@afmug.com> Subject: Re: [AFMUG] UBNT OLT Transition from Active Ethernet to GPON I need to print a retraction here. I have been talking to Martin at UBNT and he shows me the error of my ways. I do not have a 50% failure rate. In fact, it's a 0% failure rate. My signal was just too hot. I'm new to the SM Fiber game, so I'm learning as I go. I didn't realize the signal could be too hot at only -3 dB. All of my multi mode Fiber sits at -2 dB and works really well. You learn something new every day.
