I am in the process of upgrading an old HP switch to 2530 or 5130 to connecting two buildings. Because the buildings are located more than 300 m utp will not be an option. Therefore we opted for fiber SFP. I saw that the switches have 2 SFP+ ready ports available. But when I saw on the HP website
https://www.hpe.com/h20195/v2/default.a ... id=3897977, they say the very similar description on SFP+ SR transceiver, and we find a lower price on
J9150A,
JD092B,
455883-B21. which one should I buy?
