2/2 Vaan nyt sekä #SDP, että #vihreät omaavat oivan tilaisuuden viedä #RKP:n ainoa paikka - asettaa ehdolle #ruotsinkielinen, näkyvä, Biaudetin kaltainen humaani #ehdokas viemään #SFP:n ääniä Rantalalta.

EDIT: Toki myös vasemmistolla tsäänssit, esim. #SilviaModig in ja #MiaHaglund in ehdokkuuksien myötä - kaksi näkyvää ruotsinkielistä.

1/2 No eipä yllätä sen jälkeen, kun puolue petti hänet niin pahasti kuin istuvaan hallitukseen mukaan menemisellä.

Saas nähdä, menettääkö #RKP ainokaisen Stadin paikkansa, vai onnistuuko puolue nostamaan sen vaalipiirin gagosehdokkaansa, hyvin talousoikeistolaisen Marcus Rantalan eduskuntaan asti. Puolueen kannatus kuitenkin on laskussa.

Found some 1000BASE-T #SFP <-> #RJ45 modules which work with the #uboot #tftpboot of this #Xikestor #Realtek #rtl93xx switch chip. And managed to figure out how to select a port other than the first one for tftpboot (just use the same weird, non-linear port numbers as the #DTS in #OpenWrt uses.) This now simplified my test setup quite a bit.

Here I am spending 4h of my personal FTE over a Saturday lunchtime, on qualifying an aftermarket Dell VEP 1400 white box edge router from a Scottish IT recycler for #FreeBSD use. It has 6x1000BASE-T and USB 3 for 5G/4G radio. #OPNsense 26.2 serial boots just fine, but does not support the RJ45 ports or the #Qualcomm #ath10k Wi-Fi. The two #SFP ports seem to work just fine with #Cisco compat 1000BASE-T SFP modules. These are not combos (shared), I am pleased to report so far.

I've stumbled on the SFPTotal Whistle, and I've got some questions:

- Would it be possible to program fs.com #SFP optics with that? Or do they really require the FSBox?
- Assuming that the SFPTotal Whistle is essentialy just a USB to I²C adapter with an SFP-shaped hole, are there any OSHW/FLOSS projects out there I should now about instead? I don't mind tinkering. Can't I just slap an I²C interface IC on an SFP frame?

Что под капотом у DWDM

Возвращаясь к теме DWDM ( https://habr.com/ru/articles/1008314/ ) решил написать небольшую информационную статью про саму технологию. Оптическое волокно — это среда, по которой свет распространяется с минимальными потерями в определённом диапазоне длин волн. Идея спектрального уплотнения (WDM) проста: вместо одного луча света запускаем много лучей (каналов) с разными длинами волн. Обычно для длины волны используют термин лямбда. Они не мешают друг другу, как радиостанции на разных частотах. DWDM (Dense Wavelength Division Multiplexing) — это «плотное» уплотнение, когда расстояние между соседними каналами минимально, чтобы уместить как можно большее количество лямбд в «окно прозрачности» волокна.

Как построить DWDM-сеть в России
