 emily | infiniband seems cursed. | 14:35:55 |
 magic_rb | it is :P^ | 14:36:04 |
| magic_rb | * it is :P | 14:36:05 |
| magic_rb | i need to work on my thesis, which isnt about fiber optics, so im out | 14:37:36 |
| magic_rb | pls dont ping or ill never finish it :P | 14:37:46 |

Is the gpon i have here running some kind of linux or do they tend to run some embedded cursed thing? If it's Realtek or Lantiq, it's running Linux | 15:02:19 |
| K900 | If it's Huawei, it might be some weird RTOS or it might be Linux but they don't admit it | 15:02:36 |
| K900 | I don't think anyone but those three actually makes PON modem chips | 15:03:52 |
| K900 | Oh Broadcom is also a thing and also Linux but fuck Broadcom all my homies hate Broadcom | 15:05:52 |
| K900 | And Mediatek supposedly has one (1) SoC for baseline GPON that is complete Bigfoot status | 15:06:22 |

Oh Broadcom is also a thing and also Linux but fuck Broadcom all my homies hate Broadcom I wonder why rpi keeps using shitty broadcom chips | 16:05:59 |
| K900 | Because the RPi leadership is all ex-Broadcom | 16:09:33 |
| magic_rb | 10GBASE-LR is btw the standard of the transceiver i was looking at, what does the lr mean? Long range? | 16:10:33 |

Because the RPi leadership is all ex-Broadcom I love making engineering decisions politically, leads to great products i swear | 16:10:56 |
| magic_rb | Yeah long reach | 16:11:25 |
| K900 | L is long wavelength | 16:11:29 |
| K900 | R is modulation scheme | 16:11:33 |
| magic_rb | 10GBASE-SR wikipedia says its lower power use | 16:12:19 |
| magic_rb | Found a 14 euro 10GBASE-SR module from ampcom | 16:13:05 |
| magic_rb | 0.9 for sr, 1.0 watts for lr according to the seller | 16:13:45 |
| emily | LR goes longer than SR yes | 16:59:59 |
| emily | it's like 1 km vs. 10 km or whatever? | 17:00:02 |
| emily | uh | 17:00:42 |
| emily | oh right | 17:00:42 |
| emily | magic_rb: SR is for multimode | 17:00:46 |
| emily | LR is for single mode | 17:00:55 |
| emily | (LRM is for multimode. yes this confused me so much that I forgot about it) | 17:01:05 |
| emily | I found FiberMall sells "IR" (which I can only assume is non-standard for "intermediate reach") that works with SMF for cheaper than their LR transceivers. IIRC it was basically just the price of AliExpress LR ones though. | 17:01:46 |
|  Ando “Thor” Nando joined the room. | 22:04:21 |
 matthewcroughan | K900: do you ever see this?
