BPI-R4 SFP+ - DAC recommendations

Banana Pi Router design BPI-R4(MT7988)

I’m interested in buying a 2ft passive dac for a R4 in the future. Any recommendations for connecting to a cheap switch? Or anything I should watch out for?

I think in Serve the Home’s video they mention that there can be issues. I bought a switch similar to QNAP QSW-2104-2T-A

I have the QNAP QSW-2104-2S not cheap but works well (uses a Broadcom chip). Since I brought it Realtek has released its own chip and you can now find copy of that switch for about 30-35€ on Aliexpress (link) and they should works as well.

I’m using this https://www.aliexpress.com/item/1005005780965130.html with my R4 connecting it to my Zyxel xgs1930-28 and it works flawlessly.

I am using AOC cable https://www.aliexpress.com/item/1005004075266892.html without any trouble.

I also tested some SM and MM modules with LC cables, always connected to the https://www.aliexpress.com/item/1005005503868174.html directly, and everything worked as expected.

In fact, there is hw compatibility list with some sfp already tested, take a look and feel free to add what you tested: BPI‐Router‐Linux Wiki · frank-w/BPI-Router-Linux Wiki · GitHub :wink:
