I think the UBNT display on the ONT is really cool, but my application is wasted because use the ONT in a NID on the side of the house.
Even new construction out here there is no conduit to the inside and no fiber from outside to inside. It’s all Cat5e/6 today, so I go the path of least resistance. If we’re talking 10+Gbps next gen PON, then I might make available the running of fiber from the NID inside. But even then, it’s likely to sit in a wiring closet and translate to Ethernet router or cross connect to a router in another room.

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.

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" <[email protected]<mailto:[email protected]>> 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:[email protected]<mailto:[email protected]>] On Behalf Of Brett A Mansfield Sent: Wednesday, August 2, 2017 10:16 AM To: [email protected]<mailto:[email protected]> 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.
