Ways of connecting CRS326-24G-2S with RB4011iGS at 10G speeds?

What are ways of connecting CRS326-24G-2S switch with RB4011iGS router to achieve 10G speeds? RB4011iGS does not support Passive DAC modules and SFP GPON modules so I am a bit confused as what to buy.

I was thinking of buying S+AO0005 but the distance between the router and the switch in my rack is 3U at max 50 cm cable run, so I don’t need a 5m cable. Are there shorter ways of connecting the two devices whilst not going over S+AO0005 price?

Two 10GBASE-SR generic optics and a short fiber patch is probably the simplest option (and easy to lengthen if you ever need to). Two of these and a 50cm OM3 patchcord will set you back about €43, and I know they will work; I use them. You could also try their 1M active DAC or their 1M AOC, but I can’t vouch for those.

Thanks for the info!
