K900 | It has its own media layer that you need to shove L3 packets into | 13:55:30 |
K900 | That handles the whole broadcast down/unicast up thing | 13:55:59 |
K900 | And whatever other nonsense | 13:56:11 |
K900 | So the PON SFP "modules" aren't Ethernet media converters, they're actual modems that just have an SFP shaped Ethernet link coming out of the other side | 13:56:53 |
K900 | But inside is the exact same hardware as a modem box, just in a different form factor | 13:57:30 |
magic_rb | Right ive been told some can be flashed with owrt even | 13:57:54 |
K900 | I think the Lantiq ones can yeah | 13:58:07 |
K900 | But those don't do over 1GbE | 13:58:16 |
K900 | On the Ethernet side | 13:58:19 |
magic_rb | "I have openwrt in my openwrt man" | 13:58:33 |
magic_rb | In reply to @k900:0upti.me But those don't do over 1GbE Are they like older? | 13:58:47 |
K900 | Yes | 13:58:58 |
magic_rb | Is the gpon i have here running some kind of linux or do they tend to run some embedded cursed thing? | 14:01:24 |
magic_rb | Its some nokia box i think | 14:01:33 |
magic_rb | Yeah nokia | 14:01:48 |
emily | "the GPON" could probably use disambiguation. | 14:04:43 |
emily | do you mean the ONT? | 14:04:46 |
magic_rb | Uh | 14:05:02 |
magic_rb | I would send a picture | 14:05:15 |
magic_rb | But yeah | 14:05:18 |
magic_rb | Thingie that i plug in ethernet into on the wall | 14:05:33 |
emily | a box you have in your property that takes fibre optic in and spits out twisted pair or similar? | 14:05:41 |
emily | right. | 14:05:45 |
magic_rb | And it plugs into a fiber terminator box thingie | 14:05:47 |
emily | that's the ONT which is basically a modem. | 14:05:54 |
magic_rb | Like slides on | 14:05:52 |
emily | I think that the vast majority of their job is just done in dumb hardware? | 14:06:08 |
emily | but they might very well have some Linux thing for monitoring or whatever. | 14:06:18 |
emily | don't quote me on that though, I'm not an expert. | 14:06:23 |
emily | I guess the fact that all the SFP+ modules for it seem to run Linux implies that maybe there's actual smarts? | 14:06:39 |
