If you can't find it in your country try the full Alibaba listing here Hisource 4 Port 2.5g Without Power Supply Network Switch 2*10g Sfp For Ip Camera - Buy 4 Port Network Switch,2 Sfp+ Optical Ports,Best Network Switch Brands Product on Alibaba.com , I was able to order a "sample", it added an extra ~$7 in shipping. total with tax for me was just under $40. Wonder if I can order a second "sample" if I end up wanting another lol.
At this price point I'm going to use it partially as a glorified 10GB sfp+ to 2.5Gb ethernet for something that doesn't support 2.5 on the sfp+ natively, I already have a bunch of optics and such.
They were probably sloppy and used the terms interchangeably
