could 10G sfp+ DAC insert into sfp Solts?

[Freebsd1976]

I have a switch (convert from onu,Huawei ma5626-8) which have two 1.25G sfp slots , this solt use hpsp2120 sm sc transceiver module for onu and lot.
Since I convert the onu to switch and want use sfp slots uplink another switch, instead use transceiver i want use dac,.
now I already have some 10G sfp+ dac,could these sfp+ dac worked in sfp slots for 1G speed?

Not possible. Sfp+ slots normally accepts sfp modules but sfp slots does not support sfp+ modules.

I also think this is impossible util I saw a thread in ubnt forums ,
Ubiquiti Networks Community

In that thread serval guys said sfp+ worked in sfp slots,include dac and modules, this is confusing me,could someone explain?

The following is the content copy from ubnt forums:

Just bought 2x UDC-1 (Ubiquiti 10Gbps SFP+ 1mt cord) and tried......they works ok!



Connected a US-8-150W to a US-24 (both on 3.9.27.8537 on Controller 5.7.25) with 2x UDC-1 and aggregated to 2Gbps.

This what shows hovering over the SFP slot on the US-24

Same here. I just aquired a bulk load of SFP+ 10Gbe Active Brocade Direct Attach Cables and I can confirm that they work from my Unifi Switch 16port 150W towards a TP-Link SG3216.



I'm new to SFP / SFP+ and it's fasinating to see all the conflicting information. Hope that this helps people.



Intresting note: the link statisics aren't working. (See image).



iperf is running at 900Mbit from my MacBook Pro (low battery, migh affect performance) trough TB2 Network Adapter > RJ45 > TP-Link SG3216 > SFP > Brocade 10Gbit DAC > SFP > USW16p > RJ45 > Synology DS1513+
